Mouse Anti-CD22 Recombinant Antibody (clone m5/44) (CAT#: FAMAB-0046YC)

Murine mAb m5/44 was selected based on its subnanomolar affinity for CD22 and ability to be internalized into B cells. CalichDM conjugated to m5/44 caused potent growth inhibition of CD22+ human B-cell lymphomas (BCLs) in vitro.

Host: Mouse

Isotype: Mouse IgG1

Applications: ELISA, Cyt

Figure 1 Mouse Anti-CD22 Antibody (clone m5/44) in Neut.

Competitive inhibition of the binding of murine antiCD22 mAb, m5/44, to Ramos BCL by its humanized versions assembled by combinations of four distinct grafts of heavy chain (gHa-d) and two distinct grafts of light chain (gLa, gLb). Increasing concentrations of the humanized mAb were mixed with the fixed concentration of m5/44 and then allowed to bind to Ramos BCL. Binding of the murine mAb, m5/44, was monitored by indirect immunofluorescence analysis using flow cytometry. The chimeric version of m5/44 (cL cH) was also used in this evaluation as a positive control
