Scientific Data

Western Blot Detection of Human/Mouse/Rat RSK2 antibody by Western Blot. View Larger

Detection of Human/Mouse/Rat RSK2 by Western Blot. Western blot shows lysates of HEK293 human embryonic kidney cell line, PC-12 rat adrenal pheochromocytoma cell line, and NIH-3T3 mouse embryonic fibroblast cell line. PVDF membrane was probed with 0.1 µg/mL of Rabbit Anti-Human/Mouse/Rat RSK2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1518) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for RSK2 at approximately 90 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

RSK2 in Mouse Embryo. RSK2 was detected in immersion fixed frozen sections of mouse embryo using Rabbit Anti-Human/Mouse/Rat RSK2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1518) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Rabbit HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS005) and counterstained with hematoxylin (blue).

Background: RSK2

The 90 kDa ribosomal protein S6 kinases (RSK1-4) are a family of broadly expressed Ser/Thr kinases activated in response to mitogenic stimuli, including growth factors and tumor-promoting phorbol esters. RSKs are directly phosphorylated by ERK1 and ERK2, leading to RSK autophosphorylation and activation. Active RSKs appear to play a major role in transcriptional regulation by translocating to the nucleus and phosphorylating c-Fos and CREB.
