CAS 679818-59-8 分子量 149000.00 靶点: CD20; Ofatumumab is a fully human monoclonal antibody to CD20 which appears to inhibit early-stage B lymphocyte activation
Ofatumumab is a humanised anti-CD20 monoclonal antibody whose epitope is distinct from that of rituximab. The CD20 antigen is expressed on solely B cell lymphocytes. Compared with rituximab, ofatumumab binds more tightly to CD20 with a slower off-rate. Ofatumumab causes cytotoxicity in the cells that express CD20 by means of complement-dependent cytotoxicity (CDC) and antibody-dependent cellular cytotoxicity (ADCC).

例如,依据体表面积折算法,将白藜芦醇用于小鼠的剂量22.4 mg/kg 换算成大鼠的剂量,需要将22.4 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到白藜芦醇用于大鼠的等效剂量为11.2 mg/kg。
