Description

Tafasitamab (XmAb5574) is an Fc-modified, humanized monoclonal antibody that binds to the human B-cell surface antigenCD19[1][2].

In Vitro

Tafasitamab (XmAb5574) induces cytotoxicity against Mino and Jeko (MCL) cell lines? in an E/T ratio-dependent manner. Tafasitamab (XmAb5574) increases ADCP and antiproliferative? activity. Tafasitamab (XmAb5574) enhances antiproliferative apoptotic activity due to caspase-induced apoptosis[1][2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
