Western blot - Human PTPN1 (PTP1B) knockout HeLa cell line (ab265014)All lanes : Anti-PTP1B antibody [EPR22468-6] (ab252928) at 1/1000 dilution
Lane 1 : Wild-type HeLa cell lysate
Lane 2 : PTPN1 knockout HeLa cell lysate
Lysates/proteins at 20 µg per lane.
Performed under reducing conditions.
Predicted band size: 50 kDa
Observed band size: 50 kDaLanes 1- 2: Merged signal (red and green). Green - ab252928 observed at 50 kDa. Red - Anti-GAPDH antibody [6C5] - Loading Control (ab8245) observed at 37 kDa.
ab252928 was shown to react with PTP1B in wild-type HeLa cells in western blot. The band observed in knockout cell line ab265014 (knockout cell lysate ab257617) lane below 50kDa may represent truncated forms and cleaved fragments. This has not been investigated further. Wild-type HeLa and PTPN1 knockout HeLa cell lysates were subjected to SDS-PAGE. Membrane was blocked for 1 hour at room temperature in 0.1% TBST with 3% non-fat dried milk. ab252928 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at a 1 in 1000 dilution and a 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye®800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye®680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.
