產(chǎn)品詳情
簡單介紹:
重組人巨噬細胞炎癥蛋白-5 / CCL15蛋白與其它公司提供的重組蛋白不同,rHuMIP-5/CCL15蛋白產(chǎn)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(shù)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.重組人巨噬細胞炎癥蛋白-5 / CCL15蛋白(全長序列)產(chǎn)品可用于Western Blot驗證、抗體制備、蛋白檢測、ELISA等試驗中.

Formulation | Lyophilized from a 0.2 μm filtered concentrated solution in 20 mM PB, pH 7.4, 100 mM NaCl. |
Endotoxin | Less than 1 EU/μg of rHuMIP-5/CCL15 as determined by LAL method. |
Reconstitution | 重組人巨噬細胞炎癥蛋白-5 / CCL15蛋白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 | 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 | Human CCL15 is belonging to the CC chemokine family and shares 35 % amino acid homology with human HCC1 (CCL14). CCL15 is most abundant in heart, skeletal muscle and adrenal gland, and low expressed in liver, small intestine, colon, and in certain leukocytes and macrophages of the lung. It is chemotactic for neutrophils, monocytes, and lymphocytes and elicits its effects by binding to cell surface chemokine receptors like CCR1 and CCR3. CCL15 has several cleaved chains. All of them are more potent chemoattractants than CCL15. |
