Commonly used, FITC conjugates provide relatively high absorptivity, excellent fluorescence quantum yield, and good water solubility.
CD22 (BL-CAM) is a type 1 integral membrane glycoprotein with molecular weight of 130 to 140 kD. It is expressed in both the cytoplasm and cell membrane of B-lymphocytes. CD22 antigen appears early in B-cell lymphocyte differentiation at approximately the same stage as the CD19 antigen. Unlike other B-cell markers, CD22 membrane expression is limited to the late differentiation stages comprised between mature B cells (CD22+) and plasma cells (CD22-), and may thus prove useful in phenotyping mature leukemias. CD22 is also strongly expressed in hairy cell leukemia.
Analyte Specific Reagent
Phase I study of a bispecific ligand-directed toxin targeting CD22 and CD19 (DT2219) for refractory B-cell malignancies.
MHCD2201 was used in immunocytochemistry to describe a phase I dose-escalation study where DT2219 is administered to patients with relapsed/refractory B-cell lymphoma or leukemia
