Anti-Ms CD44, IM7, PE, 25tests

Engineered for multicolor flow cytometry on murine samples, this PE-conjugated monoclonal antibody from STEMCELL Technologies targets the CD44 surface glycoprotein (Pgp-1/Hermes), recognized by the widely cited clone IM7 in a rat IgG2a, κ format. CD44 is broadly expressed across hematopoietic lineages, including naïve and activated T cells, B lymphocytes, monocytes, macrophages, granulocytes, and a fraction of thymic epithelial cells, making this reagent a standard building block for mouse immunophenotyping panels used to resolve activated and memory subsets, myeloid maturation states, and lymphocyte trafficking markers.

Supplied as a single-use vial sized for 25 tests, the R-Phycoerythrin label delivers a bright, narrow emission near 578 nm with excitation around 496 nm on the blue laser line, pairing cleanly with FITC, APC, PerCP, and Pacific Blue partners in common four- to eight-color mouse flow cytometry cocktails. Recommended usage is 5 µL per test per the manufacturer's titration guidance, with sample volumes of 100 µL typical for splenocyte or bone marrow suspensions blocked with anti-FcγR.

Handling requirements reflect the light-sensitive phycoerythrin conjugate: store refrigerated, protect from light, and never freeze the vial, because freeze-thaw cycles accelerate PE fluorescence loss. The reagent is intended for research use only and is not approved for diagnostic or clinical applications.
