Anti-CD23 Antibody [S25-H]

Fluorescein-conjugated monoclonal antibody reagent from Antibodies.com targets the human CD23 antigen for direct immunofluorescence staining in flow cytometry workflows. The rabbit IgG clone S25-H is supplied as a liquid formulation in a 100T vial, with the FITC label enabling excitation on standard 488 nm blue laser lines and emission near 519 nm for multi-color panel design.

Reactive specifically with the human CD23 (FcεRII) low-affinity IgE receptor expressed on activated B lymphocytes, the reagent supports characterization of B-cell subsets in peripheral blood, lymphoid tissue preparations, and B-lymphoblastoid cell lines. The antibody is commonly applied to surface staining of PBMCs, lymphoma phenotyping panels, and studies of IgE-mediated immune regulation, where it pairs cleanly with PE- or APC-labelled lineage markers in multi-parameter panels.

Protect the vial from light throughout handling, refrigerate on receipt, and avoid freeze-thaw cycles to preserve fluorophore integrity and binding activity. Each vial contains 100 tests of ready-to-use liquid antibody used in direct staining protocols without the need for a secondary detection reagent, and the FcεRII specificity has been validated on human samples with no meaningful cross-reactivity reported on mouse, rat, or non-human primate lymphocytes.
