Human STAT2 Antibody

Detection of Human STAT2 by Western Blot. Western blot shows lysates of K562 human chronic myelogenous leukemia cell line, HeLa human cervical epithelial carcinoma cell line, and Daudi human Burkitt's lymphoma cell line. PVDF membrane was probed with 0.2 µg/mL of Human STAT2 Monoclonal Antibody (Catalog # MAB1666) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for STAT2 at approximately 115 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Western Blot Shows Human STAT2 Specificity by Using Knockout Cell Line. Western blot shows lysates of HeLa human cervical epithelial carcinoma parental cell line and STAT2 knockout HeLa cell line (KO). PVDF membrane was probed with 0.2 µg/mL of Mouse Anti-Human STAT2 Monoclonal Antibody (Catalog # MAB1666) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for STAT2 at approximately 110 kDa (as indicated) in the parental HeLa cell line, but is not detectable in knockout HeLa cell line. GAPDH (Catalog # MAB5718) is shown as a loading control. This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Detection of Human STAT2 by Western Blot Induction of type I IFN signaling by viral and nonviral stimuli is inhibited in G2/M-arrested cells. Suit2 cells were treated for 25 h with the vehicle, paclitaxel, colchicine, or ruxolitinib at 500 nM. Cells were then treated with the vehicle (untreated), TransIT reagent (0.5%, vol/vol), poly(I:C) at 10 μg/ml plus TransIT reagent, IFN-alpha at 5,000 U/ml, or VSV at an MOI of 30 based on titration on BHK-21 cells. VSV was aspirated 1 h later, and medium was added to infected wells. Cells remained in treatment for a total of 4 h, after which total protein was isolated. Western blot results for STAT1 and -2 proteins and their phosphorylated forms are shown in addition to VSV proteins. GAPDH was used to confirm that protein loading was the same across the gel. Protein names and protein sizes in kilodaltons are indicated on the left and right, respectively.
