Recombinant human epidermal growth factor, one of human growth factors, is a 6.2 kda protein containing 53 amino acid residues. Egf is a highly efficient cell division factor with many other biological effects, which mainly includes: 1. Stimulating the growth and proliferation of skin, cornea and racheal epithelium tissue in vivo. 2. Accelerating the healing process of epidermis damage on skin, cornea, etc. 3. Repressing the gastric acid excretion. 4. Accelerating the proliferation of epithelial cells in human and animals. 5. Facilitating the biosynthesis of protein, rna, dna as well as metabolic activity in epidermal cells. Purity by sds-page: 95% min Purity by hplc: 95% min Activity unit: 1x10e6iu/mg Ph value: 7.2 Storage:2-8 deg(in refrigerator) storage, stable within 36 months. 0.1mg, 1mg, 10mg freeze-dried powder or customer's package available
piperazine-N, N '- di (2-ethanesulfonic acid) |English name|PIPES |Chinese name|Piperazine-N, N '- bis (2-ethylsulfonic acid) / piperazine-1,4-diethylsulfonic acid |CAS#|5625-37-6 |Molecular weight|302.368 |Molecular formula|C8H18N2O6S2 |Storage condition|room temperature, away from light and moisture |Application|This product can not form stable complex with most metal ions, and can be used as buffer in solution system containing metal ions. It was applied to the purification of tubulin by using cellulose phosphate chromatography. The purified recombinant GTP binding protein ARF1 and ARF2 were purified by gel filtration and used as buffer to crystallize ketoenzyme from E. coli. In addition, PIPES is not suitable for redox system because it can form free radicals. In cation exchange chromatography, a low concentration of PIPES buffer should be used, because pipes has relatively large ionic strength and its pKa value is concentration dependent. |Product advantage|The purity is >99%, with good water solubility and stable process, which can ensure that the product appearance is pure white crystal powder. Desheng is a chemical reagent company specializing in blood test reagents with 14 years of R&D experience, especially has a deep research on chromogenic substrate and biological buffer. Enterprises or individuals in need can directly contact . We look forward to your calls, to join hands in creating a better tomorrow!
