Western blot analysis of human iPSC-derived cortical neurons showing detection of Tau protein using Anti-Tau (phospho Ser202 + Thr205) Antibody [AH36] (A304919) at 1:500 for Overnight. Lane 1: MW ladder. Lane 2: Control (non-disease) line. Lane 2: Ex10+16 tau mutant sample. Lane 3: P301L tau mutant sample. Load: 50ug. pSer202/pThr205 was detected using A304919. Total tau was detected using mouse anti-tau antibody (clone HT7). The bar graph on the right shows quantification of pSer202/pThr205 compared to total tau in each sample.
