Product Image-97064-716

Phenol ≥99.0% saturated with buffer pH 4.5

Catalog Number: (97064-716)
Supplier: VWR
Description: For RNA purification, it is best to use a phenol or phenol:chloroform mixture with a pH of 4.5 to 5.5. Although phenol alone will purify RNA in these extractions, messenger RNA can collect with the DNA at the inter-phase in the complete absence of chloroform. The ratio of phenol to chloroform can vary from no chloroform to a 1:1 mixture, depending on the individual tissue and the character of the RNA being purified. For many applications, a 5:1 ratio of phenol:chloroform is a recommended starting point. The phenol used for extraction protocols must be highly purified and essentially free of contamination by phenolic acid, a product of phenol oxidation. VWR’s phenol products are manufactured from the purest crystalline phenol to ensure optimal results.

Human Recombinant IGF-I (from E. coli)

Supplier: VWR International
Description: Insulin-like growth factor I (IGF-I) is a growth factor that is produced by the liver. IGF-1 production is stimulated by growth hormone (GH). IGF-I binds the insulin-like growth factor 1 receptor (IGF1R) and the insulin receptor to stimulate systemic body growth. IGF-I is one of the most potent activators of the AKT signaling pathway, which stimulates cell proliferation and inhibits programmed cell death. Mature human IGF-I is 100% homologous to bovine and porcine IGF-1 proteins.

Human Recombinant TGF-A (from E. coli)

Supplier: VWR International
Description: Tumor growth factor alpha (TGF-α) is a member of the epidermal growth factor (EGF) family. TGF-α function is mediated through binding the EGF receptor (EGFR) to activate receptor tyrosine kinase signaling. TGF-α functions as a mitogen to activate epithelial cell proliferation, growth, and differentiation. In the gastric mucosa, TGF-α production inhibits gastric acid secretion and therefore plays a central role in the pathogenesis of the stomach syndrome Ménétrier's disease. TGF-α is also produced in adult macrophages, brain cells, keratinocytes, and is widely expressed in cancer cells.

Human Recombinant IL-17F (from E. coli)

Supplier: VWR International
Description: Interleukin 17F (IL-17F), a member of the IL-17 cytokine family, is secreted by activated CD4+ T cells and monocytes.  IL-17F binds the IL-17 receptor related molecule, IL17RC, to promote the production of the interleukin 6 (IL-6), interleukin 8 (IL-8), and granulocyte macrophage colony-stimulating factor (GM-CSF) cytokines.  IL-17F also functions to regulate matrix turnover rates, inhibit endothelial cell angiogenesis, and induce the endothelial cell expression of interleukin 2 (IL-2), monocyte chemoattractant protein-1 (MCP-1), and transforming growth factor beta 1 (TGF-b1).
