產品詳情
簡單介紹:
重組大鼠催乳素蛋白與其它公司提供的重組蛋白不同,rRtProlactin蛋白產品為采用CFS的無細胞麥胚蛋白合成系統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.重組大鼠催乳素蛋白(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.

Purity | 重組大鼠催乳素蛋白> 98 % by SDS-PAGE and HPLC analyses. |
Biological Activity | Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using rat Nb2-11 cells is less than 1.0 ng/ml, corresponding to a specific activity of > 1.0 × 106 IU/mg. |
Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
Formulation | 重組大鼠催乳素蛋白Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4. |
Endotoxin | Less than 0.1 EU/μg of rRtProlactin 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 | 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. |
