Bulk anti-Human CD19 antibody (SJ25-C1) [ICH1011]

ichorbio’s bulk anti-human CD19 antibody (SJ25-C1) is manufactured in a cGMP compliant, ISO Quality Standard 9001:2015 facility. ichorbio’s low endotoxin antibodies have half the endotoxin of comparable antibodies from our competitors at less than 1.0 EU/mg. If ichorbio’s low endotoxin antibodies are not low enough we also offer ultra low endotoxin antibodies which have even less endotoxin (<0.75EU/mg) at an even higher purity (98% versus 95%). ichorbio: the best antibodies for in vivo research.

Bulk anti-human CD19 antibody (SJ25-C1) recognizes an epitope on Human CD19

This monoclonal antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype.

Anti-Human CD19 recognizes a (Mr 90 kDa) B-cell surface glycoprotein which is present at all stages of maturation. Anti-CD19 does not react with T-cells, granulocytes, monocytes, erythrocytes or platelets. The CD19 antigen is expressed on approximately 5-25% of human peripheral blood lymphocytes and approximately 60% of splenic lymphocytes.
