簡單介紹
重組人可溶性腫瘤壞死因子受體II型/ TNFRSF1B蛋白與其它公司提供的重組蛋白不同，rHusTNF RII/TNFRSF1B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(dá)出來的重組蛋白，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)則簡便高效，將蛋白純化過程中對(duì)蛋白的損傷降低到*小程度.重組人可溶性腫瘤壞死因子受體II型/ TNFRSF1B蛋白（全長序列）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.

|
Physical Appearance
|
Sterile Filtered White lyophilized (freeze-dried) powder.
|
|
Formulation
|
Lyophilized from a 0.2 μm filtered solution in PBS, pH 7.4.
|
|
Endotoxin
|
重組人可溶性腫瘤壞死因子受體II型/ TNFRSF1B蛋白Less than 0.1 EU/μg of rHusTNF RII/TNFRSF1B 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.
