Proteins are used in routine laboratory procedures such as binding enzymes or coupling peptides to carrier proteins. These kits, mixture solutions, and collagen matrices fulfill a myriad of essential laboratory functions for developing relationships between proteins and other cellular components. The stimulating proteins offered have various amino acid arrangements and functions to fulfill any sample manipulation for testing purposes in any field.

Human Recombinant IL-1alpha (Animal Free) (from E. coli)

Supplier: Shenandoah Biotechnology

Interleukin 1 alpha (IL-1α) is expressed by epithelial cells, activated macrophages, neutrophils, and endothelial cells to regulate immune responses. IL-1α signals through the IL-1 receptor, type 1 (IL-1R1) to activate the myeloid differentiation primary response 88 (MYD88) signaling pathway, which contains the cytoplasmic Toll/IL-1 receptor (TIR) domain adapter. IL-1α and the independently regulated IL-1β protein have overlapping proinflammatory activities to induce adhesion molecule expression on epithelial cells, control fever induction, initiate rheumatoid arthritis, and promote septic shock.

Mouse Th9 Cell Polarizing Recombinant Protein Bundle (rm IL-4, rh TGF-β 1) (from E. coli)

Supplier: Shenandoah Biotechnology

Cytokines for polarizing mouse T cells into Th9 cells. Th9 cells are a unique subset of T helper cells that produce IL-9. Although the exact function of IL-9 producing T cells is yet to be completely clear it is proposed that these cells could be important in inflammation and helminth infections. Th9 cells can be generated from naive CD4+ T cells in culture by culturing them in the presence of IL-4 and TGF-β 1. It also appears that IFNγ and IL-27 can inhibit the generation of Th9 cells.
