Data Examples

Western Blot Detection of Human, Mouse, and Rat p38 alpha  by Western Blot. View Larger

Detection of Human, Mouse, and Rat p38 alpha by Western Blot. Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line, HeLa human cervical epithelial carcinoma cell line, NIH-3T3 mouse embryonic fibroblast cell line, and PC-12 rat adrenal pheochromocytoma cell line. PVDF membrane was probed with 0.5 µg/mL Rabbit Anti-Human/Mouse/Rat p38 alpha Antigen Affinity-purified Polyclonal Antibody (Catalog # AF8691) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band for p38 alpha was detected at approximately 40 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Orexin B, p38 alpha, & Integrin beta 1 in Mouse Brainstem. Orexin B, p38 alpha, and Integrin  beta 1 were detected in perfusion fixed frozen sections of mouse brainstem using Human Orexin B Monoclonal Antibody (red; Catalog # MAB734), Rabbit Anti-Human/Mouse/Rat p38 alpha Antigen Affinity-purified Polyclonal Antibody (green; Catalog # AF8691), and Mouse Integrin  beta 1 Antigen Affinity-purified Polyclonal Antibody (blue; Catalog # AF2405). Tissue was incubated with primary antibodies overnight at 4 °C. Tissue was stained using NorthernLights™ 493-conjugated Anti-Rabbit IgG Secondary Antibody (green; Catalog # NL006), NorthernLights 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007), and NorthernLights 637-conjugated Anti-Goat IgG Secondary Antibody (blue; Catalog # NL002). The image of Integrin beta 1 is pseudo-colored for presentation. View our protocol for Fluorescent IHC Staining of Frozen Tissue Sections.

Simple Western Detection of Human and Mouse p38 alpha  by Simple WesternTM. View Larger

Detection of Human and Mouse p38 alpha by Simple WesternTM. Simple Western lane view shows lysates of HeLa human cervical epithelial carcinoma cell line and NIH‑3T3 mouse embryonic fibroblast cell line, loaded at 0.2 mg/mL. A specific band was detected for p38 alpha at approximately 43 kDa (as indicated) using 5 µg/mL of Rabbit Anti-Human/Mouse/Rat p38 alpha Antigen Affinity-purified Polyclonal Antibody (Catalog # AF8691). This experiment was conducted under reducing conditions and using the
12-230 kDa separation system.

Western Blot Western  Blot Shows Human p38 alpha  Specificity by Using Knockout Cell Line. View Larger

Western Blot Shows Human p38 alpha Specificity by Using Knockout Cell Line. Western blot shows lysates of HEK293T human embryonic kidney parental cell line and p38 alpha knockout HEK293T cell line (KO). PVDF membrane was probed with 0.5 µg/mL of Rabbit Anti-Human/Mouse/Rat p38 alpha Antigen Affinity-purified Polyclonal Antibody (Catalog # AF8691) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for p38 alpha at approximately 38 kDa (as indicated) in the parental HEK293T cell line, but is not detectable in knockout HEK293T cell line. GAPDH (Catalog # AF5718) is shown as a loading control. This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: p38 alpha

The p38 Mitogen-activated Protein Kinases (MAPKs) are a family of four related Ser/Thr kinases activated by proinflammatory cytokines and environmental stresses, such as UV irradiation and heat shock. Stress signals are delivered to this cascade by members of small GTPases of the Rho family (Rac, Rho, Cdc42). p38 MAPK is involved in the regulation of Hsp27 and MAPKAP-2 and several transcription factors including ATF2, STAT1, and indirectly CREB via activation of MSK1. The p38 MAPK protein also plays a role in cell differentiation, autophagy and apoptosis. Mkk3 and SEK can activate p38 MAPK by phosphorylation at Thr180 and Tyr182, which in turn activates the MAPKAP kinase 2 and regulating phosphorylation of ATF2, Mac and MEF2.
