Biological Activity

제품 설명

Teplizumab (MGA-031) is a Fc receptor non-binding anti-human CD3 monoclonal antibody. Teplizumab reduces the loss of beta-cell function. Teplizumab can be used in the research of type 1 diabetes^[1]^[2].

Isotype

Human IgG1 (L234A/L235A) kappa

Recommend Isotype Controls

Human IgG1 (L234A/L235A) kappa, Isotype Control

Species Reactivity

Human

IC₅₀ & Target

CD3E

In Vitro

Teplizumab (10 ng/mL-10 μg/mL, 5 days) induces human CD8+ T-cell proliferation^[3].
Teplizumab (6 days) increases the expression of CD25 and intracellular CTLA4 on CD8+ cells (freshly isolated PBMCs)^[3].

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

Cell Proliferation Assay^[1]

Cell Line:

Human PBMCs
Concentration:

10 ng/mL, 100 ng/mL, 1 μg/mL, 10 μg/mL.
Incubation Time:

5 days
Result:

Induced cell proliferation (measured by incorporation of [³H]thymidine in a 5-day assay.

In Vivo

Teplizumab (0.24 mg/kg, i.p.) induces migration of human CD4 T cells to the lamina propria and ablated the treatment effects of the drug on graft survival in NSG mice^[2].

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

Animal Model:

NOD/SCID IL2γc^-/- (NSG) mice (a tolergenic humanized mouse model)^[1]
Dosage:

0.24 mg/kg, 5 μg
Administration:

Intraperitoneal injection (i.p.)
Result:

Decreased CD4:CD8 ratio in the peripheral blood from 2.03 to 1.01, p < 0.05.
Decreased circulating hCD4 cells in the peripheral blood.
Decreased in the proportion of T cells in the bone marrow and lung.
Increased in the total number of human CD45+ cells infiltrating the lamina propria of the small intestine.

Immobilized Human CD3D&CD3E can bind Teplizumab. The EC₅₀ for this effect is 102.5 ng/mL.
Flow cytometric analysis of 10⁶ Jurkat cells with Teplizumab (HY-P99222, 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-Human IgG H&L (HY-P83776) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Human IgG1 kappa (HY-P99001, blue) was used as the isotype control.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
