Product Information
Description: BMSpep-57 is a potent and competitive macrocyclic peptide inhibitor of PD-1/PD-L1 interaction with an IC50 of 7.68 nM. BMSpep-57 binds to PD-L1 with Kds of 19 nM and 19.88 nM in MST and SPR assays, respectively. BMSpep-57 facilitates T cell function by in creasing IL-2 production in PBMCs.
   
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details.
