KB03-SLF

KB03-SLF is a bifunctional PROTAC, formed by conjugating the cysteine-targeting KB03 exploratory fragment with SLF (HY-114872), an FKBP12 ligand that does not support the degradation of FKBP12^NLS. KB03-SLF fails to degrade nuclear-localized FKBP12^NLS in cells, nor can it mediate the interaction between DCAF16 and FKBP12^NLS in a manner similar to KB02-SLF (HY-129610).
(Pink: FKBP51 and FKBP12 ligand (HY-114872); Blue: Cereblon ligand (HY-169968); Black: linker (HY-W040168)).

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.
