Background

This kit utilizes Time-ResolvedFluorescence Resonance Energy Transfer (TR-FRET) technology to measure theinteraction between GSPT1 and CRBN mediated by the molecular glue CC-885 andtest compounds. This method provides a simple, rapid, and high-throughputformat for detecting small molecules capable of mediating GSPT1-CRBNinteractions.

As shown, the interaction betweenGSPT1 and CRBN is detected using an anti-Tag1 antibody labeled with Eu (TR-FRETdonor) and an anti-Tag2 antibody labeled with Ac (TR-FRET acceptor). Since themolecular glue CC-885 mediates the interaction between GSPT1 and CRBN, thedonor and acceptor antibodies are brought into proximity. Excitation of thedonor antibody triggers fluorescence resonance energy transfer (FRET) to theacceptor antibody, resulting in specific emission of a 665 nm signal. Thisspecific signal is proportional to the degree of interaction between CC-885,GSPT1, and CRBN. This homogeneous assay is simple to perform and requires nowash steps.

REALLY CUTE SHOE BUT CUT WAY TOO SMALL!
Size: 8, Color: Black Patent
I received the black patent leather shoes today and they are so cute! Sadly I need to return them because they are cut way too small. I normally wear a 7.5 or 8 on dress shoes so I ordered the 8. They are so tight across the top that it's uncomfortable as soon as I put them on. They are smaller than a normal size 8 dress shoe. The big toe area is extremely uncomfortable because it doesn't allow any room for it at all, so my big toe just presses against the side and end of the shoe without even walking in them. I have very narrow feet and these still are too small for me. So I am returning them and I already ordered a 8.5 W and hope that will fit much better. The patent leather is very cute and adds just enough dressy that I can wear them with slacks or my Capri jeans. I like the slip on and the cushion foot bed because it feels soft.

Love these flats!
Size: 9 Wide, Color: Black White Faux Snake Skin, Size: 9 Wide, Color: Black White Faux Snake Skin
One of my favorite pair of flats! I’ve had these for several years and they are still comfortable, in good shape and really add a little spice to my outfits. I can wear these all day and not have any foot pain or discomfort as a result. The quality is good, fit is perfect and I tend to have difficulty with shoes due to bunions. Love these!!
