Western blot - Anti-htrA1 antibody [EPR23240-64] (AB274322)

ab274322 was shown to react with HTRA1 in wild-type HAP1 cells in Western blot with loss of signal observed in a HTRA1 knockout cell line. Wild-type HAP1 and HTRA1 knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 5% milk in TBST for 1 hr before incubation with ab274322 overnight at 4 °C at a 1/1000 dilution. Blots were incubated with secondary antibodies at 0.2ug/mL before imaging.

These data were provided by YCharOS Inc., an open science company with the mission of characterizing commercially available antibody reagents for all human proteins. Abcam and YCharOS are working together to help address the reproducibility crisis by enabling the life science community to better evaluate commercially available antibodies.

Immunoprecipitation - Anti-htrA1 antibody [EPR23240-64] (AB274322)

htrA1 was immunoprecipitated from 0.35 mg Human placenta lysate with ab274322 at 1/30 dilution (2ug in 0.35mg lysates). Western blot was performed on the immunoprecipitate using ab274322 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP)(ab131366) was used at 1/5000 dilution.
