Background

This kit uses HomogeneousTime-Resolved Fluorescence (TR-FRET) technology to measure the molecular glueBCL-XL DEGRADER-2 and test compound-mediated interaction between VHL andBCL-XL. This method enables a simple and rapid high-throughput format for screeningsmall molecules that can mediate the interaction between VHL and BCL-XL.

As shown, the interaction betweenVHL and BCL-XL is detected using an Eu-labeled anti-Tag1 antibody (TR-FRETdonor) and an Acceptor-labeled anti-Tag2 antibody (TR-FRET acceptor). Since themolecular glue BCL-XL DEGRADER-2 mediates the interaction between VHL andBCL-XL, the donor and acceptor antibodies are brought into proximity.Excitation of the donor antibody triggers Fluorescence Resonance EnergyTransfer (FRET) to the acceptor antibody, resulting in a specific emissionsignal at 665 nm from the acceptor. This specific signal is proportional to thedegree of interaction mediated by BCL-XL DEGRADER-2 between VHL and BCL-XL.This homogeneous assay is simple to perform and requires no washing steps.

Comfortable, Easy to Clean, and Held Up at Coachella
Size: 12, Color: White, Size: 12, Color: White
I’m really happy with this purchase. The shoes are very comfortable, and the product description is accurate. I followed the sizing recommendation based on my foot type and went one size up—they fit perfectly. I bought these for Coachella, and they definitely held up. I was on my feet all day, and they stayed comfortable the entire time. What impressed me most is how easy they were to keep clean. At the end of each day, I was able to wipe them down and maintain their whiteness without much effort. Once I got home, I gave them a deeper clean, and they honestly looked as good as new. Even the laces cleaned up easily. Now I’ve transitioned them into my regular work shoes, and they still look great. Overall, I’m very satisfied with this purchase and would definitely recommend them.

Great shoes that are well made, lite weight, and comfortable.
Size: 12, Color: Brown
Just received my 2nd pair of shoes from Bruno Marc in a size 12. These are really lite and comfortable. It can be dressed down to be a casual shoe or dressed up with a nice suit. These run true to size so I ordered my usual size 12 and the fit was perfect. Being my 2nd pair of Bruno Marc's, I like the quality of their shoes and each shoe is described appropriately on fit and comfort. Insole of these shoes were awesome and provided soft comfort on the feet along with a slight arch support too. Will definitely consider ordering more Bruno Marc shoes in the future.

Cushioned, comfortable, stylish and a rubber sole!
Size: 10, Color: Brown
These shoes check multiple boxes for me, comfortable, cushioned, rubber sole and stylish. As my feet grow old and worn out, I'm on a constant search for comfortable, cushioned shoes that are suitable for work and dressier occasions. I have tried many expensive shoes that look great but either lack cushioning, arch support and or comfort. One of the nice things is these shoes have a rubber sole, where most cushioned shoes have the foam soles which are great, but they tend to lack grip particularly when its damp/wet. They have average arch support, but the insole is removable and I put my own cushioned arch support. Love these!

OG Style
I am a big fan of Bruno Marc shoes. Over the years they have provided comfortable and affordable boots and shoes. These blue, tan and white soled dress sneakers are no exception. They have a nice finished look that makes them both causal and dressy. The lightweight style is still warm enough for colder mid-west winters. The box of the toes is wide and comfortable. The insole is well padded and a pleasure to wear. This is another fine pair of shoes to add to my collection and yours.

Must buy: Comfort + Casual + Well Made / Ventilated
Size: 8, Color: Brown
Just buy it! I have put in roughly 15,000 steps in this shoes in 10 days and I can't believe how comfortable they are after this much rough use in short amount of time. I highly recommend this shoes to anyone looking for comfort in casual style.
