標(biāo)簽(Tag)

None

外觀(Physical Appearance)

Sterile Filtered White lyophilized (freeze-dried) powder.

純度(Purity)

> 98% by SDS-PAGE and HPLC analyses.

生物活性(Biological Activity)

Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using serum free human MCF-7 cells is less than 2 ng/mL, corresponding to a specific activity of > 5.0 × 105 IU/mg.

內(nèi)毒素(Endotoxin)

< 1.0 EU per 1μg of the protein by the LAL method.

制劑(Formulation)

Lyophilized from a 0.2 μm filtered concentrated solution in 20 mM Tris-HCl, pH 8.0, 150 mM NaCl, with 0.02 % Tween-20.

復(fù)溶(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.

 

儲(chǔ)存條件

產(chǎn)品用冰袋裝運(yùn),可在-20℃至-80℃下保存1年。

建議第一次使用時(shí)將蛋白質(zhì)分成較小的量,并避免反復(fù)凍融循環(huán)。

 

注意事項(xiàng)

1.避免反復(fù)凍融循環(huán)。

2.為了您的安全和健康,請(qǐng)穿實(shí)驗(yàn)服,戴一次性手套進(jìn)行操作。
