鼠尾胶原蛋白I型 澄清牛瘤胃液 PD1/PDL1 重组人 PD-1 头孢吡普 重组人胰岛素
产品说明(Description)
Recombinant Mouse epidermal growth factor is produced by our E.coli expression system and the target gene encoding Asn977-Arg1029 is expressed with a 6His tag at the C-terminus.
Accession #: P01132
Known as: Pro-epidermal growth factor; Epidermal growth factor;EGF
制剂（Formulation）
Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.
质量控制（Quality Control）
Purity: Greater than 95% as determined by reducing SDS-PAGE.
Endotoxin: Less than 0.1 ng/ug (1 EU/ug) as determined by LAL test.
Bioactivity：Measured in a cell proliferation assay using BALB/c 3T3 cells.The ED50 for this effect is 0.15-1.5 ng/ml.
复溶（Reconstitution）
Always centrifuge tubes before opening.
Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100μg/ml.
Dissolve the lyophilized protein in distilled water.Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
保存（Storage）
Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
背景（Background）
EGF is a single-pass type I membrane protein,containing 8 LDL-receptor class B repeats and 9 EGF-like domains. EGF results in cellular proliferation, differentiation, and survival.EGF is a low-molecular-weight polypeptide first purified from the mouse submandibular gland, but since then found in many human tissues including submandibular gland, parotid gland. Salivary EGF, which seems also regulated by dietary inorganic iodine, also plays an important physiological role in the maintenance of oro-esophageal and gastric tissue integrity. The biological effects of salivary EGF include healing of oral and gastroesophageal ulcers, inhibition of gastric acid secretion, stimulation of DNA synthesis as well as mucosal protection from intraluminal injurious factors such as gastric acid, bile acids, pepsin, and trypsin and to physical, chemical and bacterial agents.
