The Rat GZMK (Granzyme K) ELISA immunoassay kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Rat GZMK. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rat GZMK and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Rat GZMK, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Rat GZMK. You can calculate the concentration of Rat GZMK in the samples by comparing the OD of the samples to the standard curve.

my Holy Grail Brow product thank you Katie Jane Hughes
Color: Medium Brown
This is my 3rd or 4th? re-order. I don't know what I will do if it gets discontinued for any reason:( I have very sparse , light brows. This is the only thing in the world that has ever let me make realistic brow hairs, with a small learning curve that don't look drawn on, or fade during the day. The pen will dry out if not left stored upside down. It lasts me at least a few months. I'm always ordering another one before it runs out just so that I'll have a back up. Thank you allure! Glossier has a version of this, but it's less product for more money and the tip isn't a thin as this one. I have even ordered this for friends, it's that good.

Too bad product totally dried up within a few days
Color: Taupe
I really wished this had worked: the color was perfect. At first use the ink was dry but noticeable. Second use, totally dried up. I wanted to return it and try again, but Amazon required the original packaging. Who keeps the original packaging on a $6 item?

Love these!
Color: Dark Brown
I use these everyday. They're the best pen I have found for brows. They have a thin tip perfect for hair like strokes. Hate the Ulta stopped carrying them.

Maybe a fluke?
Color: Medium Brown
I'm truly bummed because I loved this product and was so excited to find such an accurate brow pen that was a good price. I thought the search was over.. I literally got two good applications from it which were to test it out and get the feel of this pen. I did not leave the cap open and when not in use, stored vertically so the tip is pointing down (good habits for such products). Two uses and it was like it was empty. I could get a stroke here and there, but it just kept giving less and less. Maybe I did something wrong, but I've been on the hunt for a good brow pen and have tried many - I know the do's and dont's. I'm so so soo bummed because it was amazing and so relieving for the brief moment I was able to use it. I thought my search was over. I may try it again - maybe it was a fluke.. but this is a great pen if it can actually provide more than a couple uses.

The product and colors are absolutely fabulous!
Color: Medium Brown
The only disappointment I have is that the product runs out quickly. The product design, color, and mechanism is first class. Perhaps the 3 times that I’ve purchased had been sitting on the shelf for a while. Since this is similar to a paint brush, I wish the package would include a date of manufacturing so that the consumer knows what they are buying. I love the application tip. It lays down a moderate, hair-like stroke of realistic color. The time it takes to dry allows you to finish application of one whole brown, and time to blur it for a more natural look. Fantastic product.
