Human CD10 is a well known marker for common acute lymphoblastic leukemia antigen (CALLA) (4). CD10 is expressed on normal early B cells in bone marrow and is also on fetal thymocytes. CD10 expression is lost as the T and B lineage cells mature and only appears again on activated germinal center B cells. CD10 is present on neutrophils. CD10 is a neutral endopeptidase and hydrolyzes peptide bonds on the amino side of hydrophobic amino acids.

Isotype: Murine IgG1kappa

Immunogen: Membrane preparation of human B-lineage leukemia cells

Specificity: Antibody SN5c recognizes an extracellular epitope of the the human 100 kd membrane-associated peptidase CD10 (1, 2, 3).
