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.

Furin convertase inhibitor (chloromethylketone)

Supplier: Enzo Life Sciences

Highly specific, potent, irreversible, and cell-permeable competitive inhibitor of proprotein convertases: furin/SPC1 (Ki~1 nM), SPC2/PC2 (Ki=0.36nM), SPC3/PC1/PC3(Ki= 2,0nM), SPC4/PACE4 (Ki=3,6 nM), SPC6/PC5/PC6, and SPC7/LPC/PC7/PC8 (Ki=0,12 nM). Because furin activates viral glycoproteins, this inhibitor is a useful antiviral agent. In addition, it inhibits furin-dependent pro-MMP-2 activation in various cell lines, including U87 and HT1080 cells. Typical concentration range used in tissue culture is 25 to100 µm.

Mouse Recombinant Mouse Th17 Cell Polarizing Plus PB (from E. coli)

Supplier: Shenandoah Biotechnology

Cytokines for polarising mouse T cells into Th17 cells. T helper 17 cells (Th17) are a distinct type of T cell subset that are thought to be important in immunity against microbes at the epitilial and mucosal interfaces of the body. Disruption of the regular function or balance of Th17 cells is thought to be involved in several autoimmune diseases and/or opportunistic infections. Th17 cells are characterised by their ability to produce IL-17, IL-22 and IL-21. Th17 cells can be cultured from naive CD4+ T cells by culturing them in the presence of anti-CD3 and anti-CD28 stimulation with recombinant IL-6 and recombinant TGF-β 1. In some cases neutralising antibodies against IL-12, IL-4 and IFNγ are used along with recombinat cytokines IL-1 β, IL-21 and/or IL-23.

Mouse Recombinant Mouse Hpc Expansion PB (from E. coli)

Supplier: Shenandoah Biotechnology

Cytokines for expansion and cell culture of mouse hematopoietic stem cells to progenitor cells. Hematopoietic stem cells are self renewing pluripotent cells often characterized by the expression of CD34. Studies have shown that decreased expression of CD34 tends to correlate with the decreased self renewal properties and pluripotent potential. Culturing CD34+ cells in a cytokine mixture of SCF, FLT-3 Ligand, IL-6 and IL-3 for short time periods allows rapid expansion of immature and more mature hematopoietic progenitor cells in cord blood or bone marrow preparations. If the goal is to only expand the most immature progenitor and stem cells, it is recommended that a combination of TPO, SCF and FLT-3 Ligand are used (Catalog: PB-500-04). Either cytokine combination can also be supplemented with other cytokines to promote specific lineages.
