Customer Review

Based on 1 Customer Validation

KB02 is a DCAF16-recruiting ligand that covalently binds to a ligandable cysteine on DCAF16, recruiting the E3 ligase to mediate target protein degradation. KB02 serves as a DCAF16-binding fragment for the synthesis of SHP2 PROTACs.

DCAF16

All Ligands for E3 Ligase Isoforms :

In Vitro

KB02 (7.5 μM; 24 h) alone does not induce SHP2 degradation in HeLa cells but competes with SK8 for DCAF16 binding, thereby inhibiting SK8-induced SHP2 degradation^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
