產品詳情
簡單介紹：
重組人類生長調節(jié)蛋白α/ CXCL1蛋白與其它公司提供的重組蛋白不同，rHuGRO-α/CXCL1蛋白產品為采用CFS的無細胞麥胚蛋白合成系統(tǒng)表達出來的重組蛋白，可表達出對細胞有毒性、易被蛋白酶降解的蛋白；并獲得具有良好的可溶性，并有翻譯后修飾、從而部分具有功能的蛋白.同時獨有的全自動蛋白純化技術則簡便高效，將蛋白純化過程中對蛋白的損傷降低到*小程度.重組人類生長調節(jié)蛋白α/ CXCL1蛋白（全長序列）產品可用于Western Blot驗證、抗體制備、蛋白檢測、ELISA等試驗中.

| Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation | 重組人類生長調節(jié)蛋白α/ CXCL1蛋白Lyophilized from a 0.2 μm filtered concentrated solution in 20 mM PB, pH 7.4, 150 mM NaCl. |
| Endotoxin | Less than 1 EU/μg of rHuGRO-α/CXCL1 as determined by LAL method. |
| Reconstitution | We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions. |
| Storage | 重組人類生長調節(jié)蛋白α/ CXCL1蛋白This lyophilized preparation is stable at 2-8 °C, but should be kept at -20 °C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 °C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 °C to -70 °C. Avoid repeated freeze/thaw cycles. |

| Background | CXCL1 is belonging to the CXC chemokine family. It is encoded by the GRO gene now designated CXCL1. The gene for CXCL1 was initially discovered in hamster cells. In addition to the GRO gene, two GRO genes, GROβ and GROγ share 90 % and 86 % amino acid sequence identity with CXCL1/GROα. All three human GROs are members of the intercrine alpha (chemokine C-X-C) subfamily of chemokine. CXCL1 is secreted by human melanoma cells, and also expressed by macrophages, neutrophils and epithelial cells. The functional receptor for CXCL1 has been identified as CXCR2. CXCL1 has chemotactic activity for neutrophils, and plays a role in inflammation and wound healing. |
