Anti-JNK1 (1A4) Antibody

JNK1, also known as c-Jun N-terminal kinase 1, functions as a stress-responsive serine/threonine kinase within the MAPK signaling cascade, transducing cytokine, UV, and oxidative cues into phosphorylation of c-Jun and other transcription factors. Antibodies.com offers this mouse monoclonal antibody, raised against the JNK1 isoform and identified by clone 1A4, as an unconjugated, purified reagent for detecting endogenous target protein in Western blot and immunofluorescence workflows. Cross-reactivity extends across human, mouse, and rat samples, supporting comparative pathway studies in relevant cell culture models and tissue lysates. Each vial contains 100 µl of immunoglobulin in 0.1 M Tris-Glycine buffer (pH 7.4) supplemented with 150 mM NaCl, 0.2% sodium azide, and 50% glycerol as a cryoprotectant. To preserve binding activity over time, store refrigerated, protect from light, and aliquot upon arrival to limit freeze-thaw cycles across downstream experiments.
