PAI1 was immunoprecipitated from 0.35 mg HUVEC (human umbilical vein endothelial cell) whole cell lysate with ab317604 at 1/30 dilution (2ug in 0.35mg lysates). Western blot was performed on the immunoprecipitate using ab317604 at 1/1000 dilution. VeriBlot for IP secondary antibody(HRP)(ab131366) was used at 1/5000 dilution.

Lane 1 : HUVEC (human umbilical vein endothelial cell) whole cell lysate
Lane 2 : ab317604 IP in HUVEC (human umbilical vein endothelial cell) whole cell lysate
