bufferQuality Control Testing Immunoblot Analysis A 1:1000 of this lot detected phospho-IRS1 (Tyr941) in RIPA lysates from -/+ TPA treated CHO cells transfected with IRS1. Immunoblot Analysis Untreated (Lane 1) or TPA treated (Lanes 2 and 3) lysates from CHO cells transfected with IRS1 were resolved by electrophoresis, transferred to nitrocellulose, and probed with anti-phospho-IRS1 (Tyr941) for 2 hours at room temperature. Lane 3 was preincubated with the blocking peptide immunogen corresponding to phospho-IRS1 (Tyr941). Proteins were visualized via HRP and chemiluminescent detection. Arrow indicates phospho-IRS1.
