SLF

SLF is a synthetic ligand for FK506-binding protein (FKBP) with an affinity of 3.1 μM for FKBP51 and an IC50 of 2.6 μM for FKBP12. SLF can be used in the synthesis of PROTAC.

How to use

In Vitro:

Three scout fragments-KB02, KB03, and KB05 are fused, which cover two different electrophile groups (chloroacetamide and acrylamide) and display broad cysteine reactivity in the human proteome-to the SLF ligand that binds tightly and selectively to FKBP12, a cytosolic prolyl isomerase that has been frequently used to study ligand-induced protein degradation.
