Revvity Health Sciences Inc Membrane Target Systems: Somatostatin sst5 (human) membrane preparation, in CHO-K1 cells. 400 Units.
Membrane Target Systems are quality assured frozen membranes from cells that express recombinant or endogenous receptors. We submit every batch of receptor to stringent quality control testing that includes saturation radioligand binding assay to determine receptor concentration (Bmax) and affinity (Kd). Competition binding assays are performed determine affinity (Ki) against known reference agonists and antagonists. GTPgS data is also provided for some of our Gi coupled receptors. Membranes are carefully prepared and ready for a variety of HTS applications, including radioligand binding (using either proximity methods, such as FlashPlate, or classical filtration methods). Products are packaged as frozen crude membrane preparations. One assay unit is defined as micrograms of protein, defined by competition binding assay (filtration). A complete product description and recommended protocol are included on the Certificate of Analysis. Some of our receptors may be restricted for sale in

STEMCELL Technologies Human Recombinant TGF-beta 1 (Cell Culture Ready), Size: 1 mL
Conveniently and consistently add transforming growth factor beta 1 (TGF-ꞵ1) to your cultures with this cell culture-ready formulation. TGF-β1 binds to serine-threonine kinase type I and II receptors and regulates diverse cellular phenotypes through the SMAD2/3 signal transduction pathway. Use TGF-β1 in combination with basic fibroblast growth factor (bFGF) to support the maintenance of human pluripotent stem cell (hPSC) cultures (Amit et al. Biol Reprod, 2004). TGF-β1 has been used to regulate exogenous cell signaling (Massagué Nat Rev Mol Cell Biol, 2000) and modulate immune cells (Letterio & Roberts Annu Rev Immunol, 1998). Human recombinant TGF-ꞵ1 from STEMCELL is precisely reconstituted to 0.1 mg/ml in 100 mM acetic acid; EC50 is ≤ 1 ng/mL; endotoxin levels verified using the LAL method to ensure consistency for use across multiple applications. Alternative names: Cartilage-inducing factor, Differentiation inhibiting factor, TGF-ꞵ1, TGF-beta-1, Transforming growth factor beta 1.

Proteintech Group Inc Recomb. Human IFN 2B 1000ug
Animal-free Recombinant Human IFN alpha 2B is expressed in human 293 cells as a monomeric glycoprotein with an apparent molecular mass of 16 kDa. This cytokine is produced in a serum-free, chemically defined media. Production in human 293 cells offers authentic glycosylation which contributes to stability in cell growth media and other applications. The purity is greater than 95%.
Proteintech Group Inc Recomb. Hmn Thrombo. 10ug
Animal-free Recombinant Human TPO is expressed from human 293 cells as a monomeric glycoprotein with an apparent molecular mass of 80 to 85 kDa. This cytokine is produced in a serum-free, chemically defined media. Production in human 293 cells offers authentic glycosylation, contributing to stability in cell growth media and other applications. C- terminal domain glycosylation is thought to be important for the secretion of TPO from cells and for survival of TPO in the circulation.
