Recombinant Rabbit Monoclonal Anti‑CD19 Antibody targets human CD19 (B‑lymphocyte antigen), a key membrane marker expressed on B cells from early development to plasma cell stage. This antibody is produced by recombinant technology in HEK293 cells, featuring high specificity, high affinity (pM level), low background, and excellent lot‑to‑lot consistency.
