Pep-20

Catalog No.: A64204
CD47/SIRPα blocking peptide
Pep-20 is a CD47/SIRPα blocking peptide that inhibits the interaction between CD47 and SIRPα, demonstrating KD values of 2.91 μM for human CD47 and 3.63 μM for mouse CD47. With IC50 values of 24.56 μM and 12.03 μM, respectively, for blocking these interactions, Pep-20 exhibits significant anti-tumor activity. This peptide is useful in research applications focused on immune evasion in cancer therapies and interactions within the tumor microenvironment.
