Product Overview
Clone 25C36 is a rabbit monoclonal antibody that recognizes charged multivesicular body protein 2b (gene CHMP2B) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, immunoprecipitation and flow cytometry. The predicted molecular weight is 23.9 kDa, and the supplier reports an observed band at about 28 kDa.
CHMP2B is a core subunit of ESCRT-III, the protein machinery that bends and cuts membranes. It helps form intraluminal vesicles in multivesicular bodies for cargo degradation and also supports processes such as membrane repair, and mutations in CHMP2B are linked to frontotemporal dementia and ALS.

Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Synthetic peptide based on the sequence of human CHMP2B.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places charged multivesicular body protein 2b in the cytoplasm and late endosome membrane. Tissue expression noted by UniProt (human): Widely expressed. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
