產(chǎn)品詳情
簡(jiǎn)單介紹:
重組犬腫瘤壞死因子-α/ TNFSF2蛋白與其它公司提供的重組蛋白不同,rCaTNF-α/TNFSF2蛋白產(chǎn)品為采用CFS的無(wú)細(xì)胞麥胚蛋白合成系統(tǒng)表達(dá)出來(lái)的重組蛋白,可表達(dá)出對(duì)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(shí)獨(dú)有的全自動(dòng)蛋白純化技術(shù)則簡(jiǎn)便高效,將蛋白純化過(guò)程中對(duì)蛋白的損傷降低到*小程度.重組犬腫瘤壞死因子-α/ TNFSF2蛋白(全長(zhǎng)序列)產(chǎn)品可用于Western Blot驗(yàn)證、抗體制備、蛋白檢測(cè)、ELISA等試驗(yàn)中.

Purity | > 95 % by SDS-PAGE and HPLC analyses. |
Biological Activity | 重組犬腫瘤壞死因子-α/ TNFSF2蛋白Fully biologically active when compared to standard. The ED50 as determined by a cytotoxicity assay using murine L929 cells is less than 1.0 ng/ml, corresponding to a specific activity of > 1.0 × 106 IU/mg in the presence of actinomycin D. |
Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
Formulation | Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4. |
Endotoxin | Less than 1 EU/μg of rCaTNF-α as determined by LAL method. |
Reconstitution | 重組犬腫瘤壞死因子-α/ TNFSF2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. |
