Anti-MS4A2 Antibody

This rabbit polyclonal IgG reagent from Antibodies.com is raised against MS4A2, the beta subunit of the high-affinity immunoglobulin E receptor (FcεRIβ) that anchors receptor assembly on mast cells and basophils. Provided as 100 µl of unconjugated antiserum, the antibody is validated for Western blot detection of MS4A2 expression in human samples and is supplied in a single-use vial suited to downstream immunoblotting workflows. Its polyclonal profile supports recognition of multiple epitopes on the FcεRIβ chain, useful for researchers investigating allergic inflammation, IgE-mediated signalling, asthma pathways, and related mast-cell biology. Cross-reactivity with non-human species has not been characterized, so the reagent is best applied to human sample work. Store the vial refrigerated in the dark, aliquot working volumes to avoid repeated freeze-thaw cycles, and handle as research use only, since the reagent has not been validated for diagnostic or therapeutic applications.
