Western blot - Human STAT1 knockout HeLa cell lysate (AB263837)
Lane 1 : Wild-type HeLa cell lysate 20 μg
Lane 2 : STAT1 knockout HeLa cell lysate 20 μg
Lanes 1 - 2 : Merged signal (red and green). Green - ab92506 observed at 85 kDa. Red - loading control ab7291 (Mouse anti-Alpha Tubulin [DM1A]) observed at 55kDa.
ab92506 was shown to react with STAT1 alpha in wild-type HeLa cells in Western blot with loss of signal observed in STAT1 knockout cell line ab255346 (STAT1 knockout cell lysate ab263837). Wild-type HeLa and STAT1 knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 3 % milk in TBS-T (0.1 % Tween®) before incubation with ab92506 and ab7291 (Mouse anti-Alpha Tubulin [DM1A]) overnight at 4 °C at a 1 in 1000 dilution and a 1 in 20000 dilution respectively. Blots were incubated with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 h at room temperature before imaging.

ab109320 Recombinant Anti-STAT1 antibody [EPR4407] was shown to specifically react with STAT1 in wild-type HeLa cells in western blot. Loss of signal was observed when knockout cell line ab255346 (knockout cell lysate ab263837) was used. Wild-type and STAT1 knockout samples were subjected to SDS-PAGE. Membrane was blocked for 1 hour at room temperature in 0.1% TBST with 3% non-fat dried milk. ab109320 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 10000 dilution and 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.

Abcam has not and does not intend to apply for the REACH Authorisation of customers' uses of products that contain European Authorisation list (Annex XIV) substances.
It is the responsibility of our customers to check the necessity of application of REACH Authorisation, and any other relevant authorisations, for their intended uses.
Lysate preparation: Our lysates are made using RIPA buffer to which we add a protease inhibitor cocktail and phosphatase inhibitor cocktail (ratio: 300:100:10). This means that the protein of interest is denatured. If you require a native form of the protein please use the live cell version. Please refer to our lysis protocol for further details on how our lysates are prepared.
User storage instructions: Lyophilizate may be stored at 4°C. After reconstitution, store at -20°C for short-term storage or -80°C for long-term storage.

Biological function summary
The STAT1 protein influences cell survival and immune responses. It functions as a transcription factor and participates in the interferon signaling pathway. In this setting it forms a complex with other STAT proteins such as STAT2 and STAT3 to regulate gene expression. By binding to specific DNA sequences in the nucleus STAT1 alters transcription in response to extracellular signals. It contributes to antiviral defense mechanisms and antiproliferative activities in various cells.
Pathways
The STAT1 protein plays essential roles in the JAK-STAT signaling pathway and interferon signaling pathway. It operates closely with proteins such as JAK1 and TYK2 which are involved in the phosphorylation process activating STAT1. During this activation STAT1 helps initiate cellular responses to interferons a type of signaling protein released during viral infections. The JAK-STAT pathway facilitates various physiological processes including immune responses and cell growth regulation.
