SIRPα1 is expressed in human platelets. (A) SIRPα1 expression was demonstrated in purified human platelets by flow cytometry using anti-human SIRPα1 antibody (SE7C2). (B) Representative immunoblots from purified platelet lysates for SIRPα confirmed SIRPα1 (C-20) expression in purified human platelets. (C) Semi-quantitative real-time PCR of reverse transcribed RNA isolated from purified human platelets. N = 3 separate experiments with different donors.
