Anti ha agarose beads a2095

Cells were rinsed with ice-cold phosphate-buffered saline (PBS) and lysed in EBC buffer [50 mM tris (pH 7.5), 120 mM NaCl, and 0.5% NP-40] or Triton buffer [40 mM Hepes (pH 7.4), 150 mM NaCl, 2.5 mM MgCl₂, 1 mM EDTA, and 1% Triton X-100] supplemented with protease inhibitor (Thermo Fisher Scientific, A32953) and phosphatase inhibitors (phosphatase inhibitor cocktail set I and II, Calbiochem). The cell lysates were centrifuged at 13,200 rpm at 4°C for 10 min. The protein concentration of lysates was determined using NanoDrop by Bio-Rad protein assay reagent. Equal amounts of whole-cell lysates were resolved by SDS–polyacrylamide gel electrophoresis (SDS-PAGE) and immunoblotted with indicated antibodies. For immunoprecipitation (IP), 2000 to 5000 μg of lysates were incubated with agarose-conjugated antibodies for 3 to 5 hours at 4°C. Immunoprecipitants were washed three times with NETN buffer [20 mM tris (pH 8.0), 150 mM NaCl, 1 mM EDTA, and 0.5% NP-40] or Triton buffer before being resolved by SDS-PAGE.
