Antibody-bead conjugates were prepared by adding 2 µg of TSC1 monoclonal antibody (Product # 370400) with 30 µL of protein G-Sepharose beads and rocked overnight at 4°C. 1 mg of lysate was incubated with an antibody-bead conjugate for 2 hours at 4°C. Following centrifugation and multiple washes, 10% starting material (SM), 10% unbound fraction (UB) and immunoprecipitated fraction (IP) were processed for immunoblot using a different antibody (Product # PA5-116079). Ponceau stained transfer of blot is shown. Data courtesy of YCharOS Inc., an open science company with the mission of characterizing commercially available antibodies using knockout validation.
