Product Specification
| Usage | Required experimental equipment: 1. Microplate reader (450nm) 2. High-precision pipettes and pipette tips: 0.5-10uL, 5-50uL, 20-200uL, 200-1000uL 3. 37°C incubator 4. Distilled or deionized water Sample preparation and requirements: Tissue homogenization: Rinse the tissue with pre-chilled PBS (0.01M, pH 7.4) to remove residual blood (lysed red blood cells in the homogenate will affect the measurement results). Weigh and mince the tissue. Add the minced tissue to the appropriate volume of PBS (generally a 1:9 weight-to-volume ratio, e.g., 1g of tissue sample to 9mL of PBS. The specific volume can be adjusted according to experimental needs and recorded. It is recommended to add protease inhibitors to the PBS) in a glass homogenizer and grind thoroughly on ice. To further lyse tissue cells, the homogenate can be sonicated or repeatedly freeze-thawed. Finally, centrifuge the homogenate at 5000×g for 5-10 minutes and remove the supernatant for analysis. Cell culture supernatant: Centrifuge at 1000×g for 20 minutes. Remove the supernatant for analysis or store at -20°C or -80°C, but avoid repeated freeze-thaw cycles. Pre-Assay Preparation: 1. Remove the reagent kit from the refrigerator 10 minutes in advance and equilibrate to room temperature. 2. Prepare the standard gradient working solution: Add 1 mL of universal diluent to the lyophilized standard, let stand for 15 minutes to completely dissolve, then gently mix (concentration 20 ng/mL). Then dilute to the following concentrations: 20 ng/mL, 10 ng/mL, 5 ng/mL, 2.5 ng/mL, 1.25 ng/mL, 0.625 ng/mL, 0.3125 ng/mL, and 0 ng/mL. Serial dilution method: Take seven EP tubes and add 500uL of universal diluent to each tube. Pipette 500uL of the 20ng/mL standard working solution into the first EP tube and mix thoroughly to make a 10ng/mL standard working solution. Repeat this procedure for subsequent tubes. The last tube is used as a blank well; there is no need to pipette liquid from the penultimate tube. See the figure below for details. 3. Preparation of biotinylated detection antibody working solution: Centrifuge the concentrated biotinylated antibody at 1000×g for 1 minute 15 minutes before use. Dilute the 100× concentrated biotinylated antibody to a 1× working concentration with universal diluent (e.g., 10uL concentrate + 990uL universal diluent). Prepare and use immediately. 4. Prepare the enzyme conjugate working solution: 15 minutes before use, centrifuge the 100× concentrated enzyme conjugate at 1000×g for 1 minute. Dilute the 100× concentrated HRP enzyme conjugate to a 1× working concentration with universal diluent (e.g., 10 μL of concentrate + 990 μL of universal diluent). Prepare immediately. 5. Prepare the 1× wash solution: Dispense 10 mL of 20× wash solution into 190 mL of distilled water (concentrated wash solution removed from the refrigerator may crystallize; this is normal. Allow to stand at room temperature until the crystals have completely dissolved before preparing). Procedure: 1. Remove the desired strips from the aluminum foil bag after equilibration at room temperature for 10 minutes. Seal the remaining strips in a ziplock bag and return to 4°C. 2. Sample addition: Add 100 μL of sample or standard of varying concentrations to the corresponding wells. Add 100 μL of universal diluent to the blank wells. Cover with a film and incubate at 37°C for 60 minutes. (Recommendation: Dilute the sample to be tested at least 1-fold with universal diluent before adding it to the ELISA plate. This will reduce the impact of matrix effects on the test results. The sample concentration should be multiplied by the corresponding dilution factor when calculating the final sample concentration. It is recommended to run replicates for all test samples and standards.) 3. Add Biotinylated Antibody: Remove the ELISA plate and discard the liquid without washing. Add 100 μL of Biotinylated Antibody Working Solution directly to each well. Cover with a film and incubate at 37°C for 60 minutes. 4. Wash: Discard the liquid and add 300 μL of 1x Wash Solution to each well. Let stand for 1 minute, shake off the wash solution, and pat dry on absorbent paper. Repeat this process three times (a plate washer can also be used). 5. Add Enzyme Conjugate Working Solution: Add 100 μL of Enzyme Conjugate Working Solution to each well. Cover with a film and incubate at 37°C for 30 minutes. 6. Washing: Discard the liquid and wash the plate five times as in step 4. 7. Adding substrate: Add 90 μL of substrate (TMB) to each well, cover with a sealing film, and incubate at 37°C in the dark for 15 minutes. 8. Adding stop solution: Remove the ELISA plate and add 50 μL of stop solution directly to each well. Immediately measure the OD value of each well at a wavelength of 450 nm. Calculating experimental results: 1. Calculate the average OD value of the standard and sample replicates and subtract the OD value of the blank well as a correction factor. Plot the standard curve of the four-parameter logistic function on double-logarithmic graph paper, with concentration as the horizontal axis and OD value as the vertical axis. 2. If the sample OD value is higher than the upper limit of the standard curve, dilute the sample appropriately and retest. Multiply the sample concentration by the corresponding dilution factor. |

| Theory | This kit uses a double-antibody sandwich enzyme-linked immunosorbent assay (ELISA). Sample, standard, biotin-labeled detection antibody, and HRP conjugate are sequentially added to microwells pre-coated with a cyclin D1 capture antibody. After incubation and washing, the sample is developed using the substrate TMB. TMB is converted to blue by HRP peroxidase and to yellow by acid. The intensity of the color is positively correlated with the amount of cyclin D1 in the sample. The absorbance (OD) is measured at 450 nm using a microplate reader to calculate the sample concentration. | |||||||||||||||||||||||||||||||||

|||||||||||||||||||||||||||||||||
| Background | Cyclin D1 is a protein encoded by the CCND1 gene. The CCND1 gene encodes the cyclin D1 protein. This gene is located on the long arm of chromosome 11 (band 11q13). It is 13,388 base pairs long and translates to 295 amino acids. Cyclin D1 is expressed in all adult tissues, except cells derived from bone marrow stem cells (both lymphoid and myeloid lineages). Its overexpression has been shown to be associated with early cancer onset and tumor progression, and it can contribute to tumorigenesis by increasing anchorage-dependent growth and angiogenesis through VEGF production. | |||||||||||||||||||||||||||||||||
| General Notes | 1. Strictly adhere to the specified incubation time and temperature to ensure accurate results. All reagents must be at room temperature (20-25°C) before use. Refrigerate reagents immediately after use. 2. Improper plate washing may result in inaccurate results. Ensure that all liquid in the wells is aspirated thoroughly before adding substrate. Do not allow the wells to dry out during incubation. 3. Remove any residual liquid and fingerprints from the bottom of the plate, as this will affect the OD value. 4. The substrate developer solution should be colorless or very light in color. Do not use substrate solution that has turned blue. 5. Avoid cross-contamination of reagents and specimens to prevent erroneous results. 6. Avoid direct exposure to strong light during storage and incubation. 7. Do not expose any reagents to bleaching solvents or the strong fumes emitted by bleaching solvents. Any bleaching agent will destroy the biological activity of the reagents in the kit. 8. Do not use expired products, and do not mix components with different product numbers and batches. 9. Recombinant proteins from sources other than the kit may not be compatible with the antibodies in this kit and will not be recognized. 10. If there is a possibility of disease transmission, all samples should be managed properly and samples and testing devices should be handled according to prescribed procedures. |

Well written
Format: Paperback
Randy Clark is a pillar in healing ministry. He spent so many years studying this specific area of ministry and the way he wrote this book was backed with research, data, and knowledgeable sources. I was very impressed by the way he put together this book and shared stories and testimonies of his experience with faith and healing. Highly recommend!

Personal experience welded together with history and logic.
Format: Kindle
I heard Randy Clark's name come up on a YouTube video of Bill Johnson's teaching. When I saw that this book was available on the Christian Author's Network on Facebook, I had to have a copy. I love the way Mr. Clark boldly lays out the different beliefs among people groups concerning healing. The way that he pulls together the questions all of us think concerning why some people are healed and others are not is so enlightening. His honesty and sincerity make the reading so easy to jump into. He does not condemn anyone for their beliefs, and is quick to lay out his own questions and answers as well as his own unanswered questions about healing. And the main attraction of this book to me is that it is all scripturally-based. In my opinion, Mr. Clark welds together the logical scientific train of thought with the undeniable Word of God. This is a great book full of personal experience, history and in-depth study of the scriptures concerning healing and how to receive a personal breakthrough and to be a conduit for the Holy Spirit to flow through for the healing of others. Great, anointed book!

Clear, Readable, Informative, Biblical, and Practical
Format: Kindle
This is one of the best guides to what healing ministry is all about. Clark covers a plethora of biblical, theological, and practical aspects of healing: objections, testimonies, questions, various schools of thought, and the mystery of some being healed and others not. Clark writes well and both those with theological degrees (like myself) and those relatively new to Christianity should be able to get something out of this book. I especially appreciate his irenic tone and his stalwart rejection of the dreadful notion that God wills suffering. I can’t think of a better introduction to healing ministry than this. Equal to, yes, but not better.

This writer lives it, what others only dream about. Let it become real in your life.
Format: Kindle
Good solid teaching. He is a great expert on this kind of thing. It does get academic as he refers and quotes papers he had to do in his research. I got a lot of good teaching and insights from a man who is doing the Jesus stuff.
