簡單介紹
Recombinant Human TNF-α/TNFSF2, Variant由于有些塑料管壁對某些蛋白有較強的吸附作用，溶液中的蛋白很容易粘附在管壁上，并且粘附后的蛋白很難與管壁分離。而載體蛋白(Carrier protein，如0.1% BSA???)的主要作用是預先封閉塑料管壁上的蛋白結合位點，使細胞因子或重組蛋白不會粘附于管壁。Recombinant Human TNF-α/TNFSF2, Variant所以一定要使用產品簡介中Reconstitution一欄的信息配制儲存液。

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 0.1-1.0mg/ml. Stock solutions should
be apportioned into working aliquots and stored at ≤-20℃. Further dilutions should be made in
appropriate buffered solutions.

Background
|
The clinical
use of the potent antitumor activity of TNF-α has been limited by
the proinflammatory side effects including fever, dose-limiting hypotension,
hepatotoxicity, intravascular thrombosis, and hemorrhage. Designing
clinically applicable TNF-αmutants with low systemic
toxicity has been an intense pharmacological interest. Human TNF-α, which binds to the murine TNF-R55 but not to the murine TNF-R75,
exhibits retained antitumor activity and reduced systemic toxicity in mice
compared with murine TNF-α, which binds to both
murine TNF receptors. Based on these results, many TNF-α mutants that selectively bind to TNF-R55 have been designed.
These mutants displayed cytotoxic activities on tumor cell lines in vitro,
and exhibited lower systemic toxicity in vivo.

保存條件:
-20℃或更低溫度保存，至少一年有效。由于蛋白的每次凍融均會引起部分失活，所以**配制成相應濃度的儲存液后(請根據產品簡介中Reconstitution一欄的信息配制儲存液)，須分裝后-20℃或更低溫度凍存，以避免反復凍融。
注意事項:
由于有些塑料管壁對某些蛋白有較強的吸附作用，溶液中的蛋白很容易粘附在管壁上，并且粘附后的蛋白很難與管壁分離。而載體蛋白(Carrier protein，如0.1% BSA等)的主要作用是預先封閉塑料管壁上的蛋白結合位點，使細胞因子或重組蛋白不會粘附于管壁。所以一定要使用產品簡介中Reconstitution一欄的信息配制儲存液。
