簡單介紹
Recombinant Human IFN-α2b, Ecoli.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(yù)先封閉塑料管壁上的蛋白結(jié)???位點，使細(xì)胞因子或重組蛋白不會粘附于管壁。Recombinant Human IFN-α2b, Ecoli.所以一定要使用產(chǎn)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
|
IFN-αs are proteins secreted by leukocyte. They are mainly involved in
innate immune response against viral infection. The IFN-α family has 13 subtypes and 23 different variants. The individual
proteins have molecular masses between 19-26kDa and consist of proteins with
lengths of 156-166 and 172 amino acids. All IFN-α subtypes possess a common conserved sequence region between amino acid
positions 115-151 while the amino-terminal ends are variable. Many IFN-alpha
subtypes differ in their sequences at only one or two positions. Naturally
occurring variants also include proteins truncated by 10 amino acids at the
carboxy-terminal end.

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(yīng)濃度的儲存液后(請根據(jù)產(chǎn)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(fù)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(yù)先封閉塑料管壁上的蛋白結(jié)合位點，使細(xì)胞因子或重組蛋白不會粘附于管壁。所以一定要使用產(chǎn)品簡介中Reconstitution一欄的信息配制儲存液。
本產(chǎn)品**于專業(yè)人員的科學(xué)研究用，不得用于臨床診斷或**，不得用于食品或藥品，不得存放于普通住宅內(nèi)。
為了您的**和健康，請穿實驗服并戴一次性手套操作。
- 溫馨提示：為規(guī)避購買風(fēng)險，建議您在購買前務(wù)必確認(rèn)供應(yīng)商資質(zhì)與產(chǎn)品質(zhì)量。
