Human recombinant IFN-alpha 2b (from E. coli)

Supplier: GENSCRIPT

Interferon-Alpha 2b (IFN-Alpha 2b) produced by leukocytes is a member of interferon family. IFN-alpha is mainly involved in innate immune response against a broad range of viral infections. IFN-alpha 2 has three acid stable forms (a,b,c) signaling through IFNAR2. IFN-alpha contains four highly conserved cysteine residues which form two disulfide bonds, one of which is necessary for biological activity.

Mouse T Regulatory Cell Polarizing Recombinant Protein Bundle (rm IL-2, rh TGF-β 1) (from E. coli)

Supplier: SHENANDOAH BIOTECHNOLOGY

Cytokines for polarizing T cells into T regulatory cells. T regulatory cells (Tregs) are a subset of T cells that suppress immune function. They are characterized by the expression of CD4, CD25 and Foxp3 and are known to produce immunosuppressive cytokines TGF-β 1 and IL-10. Tregs can be cultured from naive CD4+ T cells by culturing them in the presence of IL-2 and TGF-β 1 with CD3 and CD28 stimulation. In some cases cells are also cultured with neutralizing antibodies to IL-4, IFNγ and IL-12 and/or retinoic acid.
