Detects human JNK1 in direct ELISAs and human, mouse, and rat JNK1 expressed predominantly as p46 JNK (isoforms 2 and/or 3, both 384 aa), with lesser amounts of p54 JNK (isoforms 1 and/or 4, both 427 aa), in Western blots. In Western blots, no cross-reactivity with recombinant human (rh) JNK2 or rhJNK3 is observed.

Detection of Human, Mouse, and Rat JNK1 by Western Blot.
Western blot shows lysates of CHP-100 human neuroblastoma cell line, C6 rat glioma cell line, and C2C12 mouse myoblast cell line. PVDF membrane was probed with 1 µg/mL Mouse Anti-Human/Mouse/Rat JNK1 Monoclonal Antibody (Catalog # MAB17761) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band for JNK1 was detected at approximately 46 kDa and 54 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 4.
Western blot shows recombinant human JNK1, JNK2, and JNK3 (1 ng/lane). PVDF membrane was probed with 1 µg/mL Mouse Anti-Human/Mouse/Rat JNK1 Monoclonal Antibody (Catalog # MAB17761) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band for JNK1 was detected at approximately 46 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 4.
JNK1 in MCF‑7 Human Cell Line.
JNK1 was detected in immersion fixed MCF‑7 human breast cancer cell line using Mouse Anti-Human/Mouse/Rat JNK1 Monoclonal Antibody (Catalog # MAB17761) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cell surfaces. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

The c-Jun N-terminal kinases (JNKs) are encoded by three genes: JNK1, JNK2, and JNK3. Members of the MAPK superfamily, JNKs are activated by environmental stresses and inflammatory cytokines. JNK1, also known as SAPK1 gamma and MAPK8, is expressed as four isoforms generated by alternative splicing. JNK1 is activated by dual phosphorylation at T183 and Y185 by the MAPK kinases MKK4 and/or MKK7.
