Description

Ocrelizumab (Ocrevus) is a humanized anti-CD20 monoclonal antibody. Ocrelizumab can induce B cell depletion and inhibit multiple sclerosis lesions in mice through antibody dependent cytotoxicity (ADCC)[1][2].

In Vivo

Ocrelizumab (7.5 mg/kg; once daily; 18 days; s.c. or i.v.) inhibits lesions in multiple sclerosis mice by inducing B cell exhaustion through antibody dependent cytotoxicity (ADCC)[1].
Ocrelizumab (50 μg; repeat administration on days 7, 14, and 21; i.v.) can reduce B and T cells in the blood, lymph nodes, and spleen of C57BL/6 mice[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: HuCD20 mice with chronic DTH-TLS lesions[1].
Dosage: 7.5 mg/kg
Administration: Subcutaneous injection (s.c.) or intravenous injection (i.v.); once daily; 18 days; initiated on Days 63, 70 and 75 post lesion induction
Result: Reduced the number of CD19+ cells and MS like lesions in the spleen and lymph nodes of mice.
Animal Model: C57BL/6 mice [2].
Dosage: 50 μg
Administration: Intravenous injection (i.v.); repeat administration on days 7, 14, and 21
Result: Reduced the total CD19+ B cells and CD4, CD8 T cells in the blood, spleen, and LN.

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.
