Rat IgG2a kappa, Isotype Control is a monoclonal antibody derived from rats, representing the immunoglobulin G2a (IgG2a) subclass with a kappa light chain. Rat IgG2a kappa, Isotype Control exhibits high efficiency in inducing K cell mediated cytotoxicity. Rat IgG2a kappa, Isotype Control is utilized in research investigating the roles of different immunoglobulin subclasses in tumor immunology. Rat IgG2a kappa, an isotype control, can be used as an isotype control for Anti-Mouse PD-1 Antibody (RMP1-14) (HY-P99144), Anti-Mouse CD11a/LFA-1α Antibody (M17/4) (HY-P990801), and Anti-Mouse IL-2 Antibody (S4B6-1) (HY-P990796).

: Rat IgG2a kappa, Isotype Control purchased from MedChemExpress. Usage Cited in: Small. 2025 Sep 15:e04715. [Abstract]; Mouse NSCLC cells LLC were injected into the tail vein of C57BL/6 mice, with saline/IgG (Rat IgG2a kappa, Isotype Control, 200 µg; i.p; once every 3 days for a total of 4 doses) as a control, and separate or combined injection of Anti-PD1 IgG, empty LT-LNPs, nonLT-STING-LNPs, and LT-STING mRNA-LNPs. Isolated lung phenotype showed that both separate injection of Anti-PD1 IgG or LT-STING mRNA-LNPs significantly reduce the number of lung metastases in mice, and combined injection has the most significant inhibitory effect.

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.
