Human/Mouse/Rat TC-PTP Antibody

Detection of Human/Mouse/Rat TC‑PTP by Western Blot. Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line and TS1 mouse helper T cell line. PVDF membrane was probed with 0.5 µg/mL Mouse Anti-Human/Mouse/Rat TC-PTP Monoclonal Antibody (Catalog # MAB1930) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). For additional reference, Recombinant Human PTP1B (Catalog # 1366-PT) and Recombinant Human TC-PTP aa 2-314 (Catalog # 1930-PT) (1 ng/lane) were included. A specific band for TC-PTP was detected at approximately 45 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Detection of Mouse TC-PTP/PTPN2 by Western Blot Effects of TC-PTP deficiency on STAT3 dephosphorylation in keratinocytes following TPA treatment.Total cell lysates were resolved by SDS-PAGE and immunoblotted with antibodies specific for STAT3 and phosphorylated STAT3 (p-STAT3). (A) 3PC keratinocytes were treated with 10, 20, 50 and 100 nM of TPA for 1 h. (B) 3PC keratinocytes were cultured in the presence of 5, 10, 20 and 50 μM Na3VO4 for 6 h. (C) 3PC keratinocyte were cultured with 50 μM of Na3VO4 for 2 h before treatment with 100 nM TPA. Cells were collected 6 h after TPA treatment. (D) 3PC keratinocytes were transfected with siRNA specific for Ptpn2. Cells were collected 1 h after TPA (100 nM) treatment. (E) 3PC keratinocytes were treated with 20, 50 and 100 nM of TPA for 1 h. Cells were collected at the indicated time after TPA treatment. (F–G) Control (scrambled) and TC-PTP-knockdown keratinocytes were treated with TPA (20 nM) for 1 h. Following TPA treatment, cells were collected at the indicated time. (G) *At 3 h of incubation, control and TC-PTP-knockdown keratinocytes were re-treated with TPA for 1 h. Cells were then collected 4 h after second TPA treatment.
