Narsoplimab (OMS 721) is a high-affinity fully human immunoglobulin gamma 4 (IgG4) monoclonal antibody that binds MASP-2 and blocks lectin pathway activation. Narsoplimab can be used in research of hematopoietic stem-cell transplantation and SARS-CoV-2[1].
in vivo
Narsoplimab (10 mg/kg; i.v.; WT and Masp2-/- (KO) mice) decreases percentage of lymphocytes (Lym%) and increases percentage of neutrophils (Neu%)[1].
Animal Model:
WT and Masp2-/- (KO) mice (C57BL/6N, female, 12-15 weeks old)[1]
Dosage:
10 mg/kg
Administration:
Intravenous injection
Result:
Decreased percentage of lymphocytes (Lym%) and an increased percentage of neutrophils (Neu%).
