Anti-Ms CD19, 6D5, PB, 100µg

This Pacific Blue-conjugated rat monoclonal antibody targets the murine CD19 antigen and is supplied by STEMCELL Technologies as a 100 µg vial sized for dozens of flow cytometry staining panels. Clone 6D5 binds an extracellular epitope on the B-lymphocyte lineage marker CD19, enabling clear resolution of pro-B, pre-B, immature, and mature B cells from splenocyte, bone marrow, or lymph node suspensions during multicolor fluorescence-activated cell sorting. The Pacific Blue fluorophore is excited efficiently by the 405 nm violet laser and emits near 455 nm, making it a dependable option for high-parameter immunophenotyping panels in which B cell populations must be distinguished alongside T cell, myeloid, and progenitor markers.

The purified immunoglobulin is provided in a single-use vial and pairs naturally with dump-channel strategies for excluding non-B lineages. Researchers commonly titrate the reagent on a small aliquot of cells before committing larger staining volumes, particularly when working with limited primary samples. Each lot is validated for specificity against the murine B cell compartment, helping reduce background binding during in vivo adoptive-transfer tracking or ex vivo depletion experiments, and the conjugate is formulated for direct staining of cell suspensions without secondary antibody amplification.
