產(chǎn)品詳情
簡單介紹：
重組人嗜酸性粒細(xì)胞趨化因子-2 / CCL24蛋白與其它公司提供的重組蛋白不同，rHuEotaxin-2/CCL24蛋白產(chǎn)品為采用CFS的無細(xì)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(xì)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.重組人嗜酸性粒細(xì)胞趨化因子-2 / CCL24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.

| Biological Activity | 重組人嗜酸性粒細(xì)胞趨化因子-2 / CCL24蛋白Fully biologically active when compared to standard. The biological activity determined by a chemotaxis bioassay using human peripheral blood eosinophils is in a concentration of 50-100 ng/ml. |
| Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation | 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 rHuEotaxin-2/CCL24 as determined by LAL method. |
| Reconstitution | 重組人嗜酸性粒細(xì)胞趨化因子-2 / CCL24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 | CCL24 is a secreted protein, encoded by CCL24 gene in humans located on Chr.7, and produced by activated monocytes and T lymphocytes. CCL24 has functions of chemotactic activity for resting T-lymphocytes and eosinophils, but none for monocytes and activated lymphocytes. The plasma levels of CCL24 and the aspirin-exacerbated respiratory disease (such as asthma) morbidity rate have positive correlation. |
