Anti-p38 beta Antibody [P12-E]

This rabbit monoclonal antibody, clone P12-E, is raised against p38 beta (MAPK11), a stress-activated serine/threonine kinase that participates in MAPK signaling cascades alongside the related p38 alpha isoform. Conjugated to FITC, the reagent enables direct fluorescent detection without a secondary antibody step, and is supplied as a liquid formulation sized at 100T (100 tests). It is validated for flow cytometry (FC) on human samples, where it can be used to assess p38 beta expression in immune subsets, peripheral blood mononuclear cells, or cultured cell lines.

From Antibodies.com, the antibody is provided as a monoclonal of rabbit origin with an IgG isotype, offering batch-to-batch consistency and a defined epitope recognized by clone P12-E. The FITC label emits in the green channel (excitation near 488 nm), making it compatible with standard flow cytometry laser configurations. Researchers studying inflammatory signaling, cellular stress responses, or isoform-specific MAPK pathway activation can use this reagent to discriminate p38 beta from other family members in single-cell analyses. The product is intended for research use only and should be stored protected from light to preserve fluorophore activity.
