Down Arrow Up Arrow

The CD19 antibody, clone 4G7, is derived from hybridization of P3-X63-Ag8.653 mouse cells with spleen cells from BALB/c mice immunized with human chronic lymphocytic leukemia (CLL) cells.

The CD19 (Leu-12) antibody recognizes a human B-lymphocyte antigen, with a molecular weight of 90 kilodaltons (kDa).

Format Details
Down Arrow Up Arrow
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
