CD28 molecule exists on the surface of most T cells and is considered to be a specific surface molecule of T cells. The responsiveness of T cells to antigens is mainly mediated by the CD3/TCR complex, but it also depends on the cooperation of other molecules on the surface of T cells. T cells can be effectively activated through a variety of ways such as CD3/TCR, CD2 and CD28. Mononuclear cells isolated from peripheral blood, bone marrow or cord blood can be cultured for a certain period of time in the presence of CD3, CD28 monoclonal antibodies and various cytokines to obtain CIK (Cytokine-induced Killer) with tumor cell killing activity cell.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.

Recombinant Human USP14 (E.coli, N-6His)
USP14 belongs to the ubiquitin-specific processing (USP) family which is a deubiquitinating enzyme (DUB) with His and Cys domains. USP14 acts also as a physiological inhibitor of endoplasmic reticulum-associated degradation (ERAD) under the non-stressed condition by inhibiting the degradation of unfolded endoplasmic reticulum proteins via interaction with ERN1. |
Recombinant Human EpCAM/Trop-1 (Mammalian, C-Fc)
Epithelial Cell Adhesion Molecule (EpCAM) is a signal type I transmembrane glycoprotein. EpCAM plays a role in embryonic stem cells proliferation and differentiation; it up-regulates the expression of FABP5, MYC and Cyclin A and Cyclin E. It is highly and selectively expressed by undifferentiated embryonic stem cells. |
