Muromonab
Based on 1 Customer Validation
Muromonab (Muromonab-CD3; OKT3) is a mouse monoclonal antibody targeting the CD3 antigen. Muromonab specifically binds to the CD3 antigen on the surface of human and higher primate T cells. Muromonab blocks the function of T cell receptors to recognize foreign antigens and inhibits T cell-mediated immune responses, including cell-mediated lymphocyte lysis and T cell proliferation responses. Muromonab can be used to study acute kidney, liver, heart and combined kidney-pancreas transplant rejection, and can also be used to study graft-versus-host disease in bone marrow transplant patients.

In Vitro
Muromonab blocks cytotoxic T cell function and inhibits T cell proliferation[1].
Muromonab binds to the CD3 antigen on T cells, resulting in rapid clearance/depletion of CD3+ T cells in the extracorporeal circulation and reduction of CD4+ and CD8+ subsets[1].
Muromonab blocks both the induction and effector phases of cell-mediated lympholysis, inhibits T cell proliferation in response to major histocompatibility complex antigens, and modulates CD3 antigen expression on the surface of T cells.[1]
Muromonab also induces the release of cytokines such as IL-2 and IFN-γ, thereby promoting the production of early immune activation markers[1].
Curcumin (HY-N0005) and Sirolimus (HY-10219) inhibit muromonab-induced human peripheral blood mononuclear cell (PBMC) proliferation in a concentration-dependent manner (IC50=2.8 μM and 1.1 ng/mL), respectively, and their combined use at low concentrations had a synergistic effect[6].

In Vivo
The average steady-state plasma trough concentration of Muromonab (5 mg; intravenous injection; 2-3 times) is approximately 0.9 mg/L, a plasma concentration that has the function of blocking cytotoxic T cells[1].
Muromonab (0.1 mg/kg/day; intravenous; 10-14 days) causes massive lymphocyte depletion[5].

Flow cytometric analysis of 106 Jurkat cells labeling Muromonab (HY-P99152, red). Cells were fixed with 4% paraformaldehyde. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. Alexa Fluor® 488-conjugated AffiniPure Goat Anti-Mouse IgG H&L (HY-P8005) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Mouse IgG2a (HY-P99978, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).
