简单介绍
Recombinant Human IFN-α1b由于有些塑料管壁对某些蛋白有较强的吸附作用，溶液中的蛋白很容易粘附在管壁上，并且粘附后的蛋白很难与管壁分离。而载体蛋白(Carrier protein，如0.1% BSA等)的主要作用是预先封闭塑料管壁上的蛋白结合位点，使细胞因子或重组蛋白不会粘附于管壁。Recombinant Human IFN-α1b所以一定要使用产品简介中Reconstitution一栏的信息配制储存液。

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
|
Interferon
alpha-1, also named interferon alpha-D, is belonging to the type I interferon
family and is encoded by the IFNA1gene in humans. Interferon alpha-1 is
expressed in peripheral blood leukocytes and lymphoblastoid cells. IFNα-1 contains four highly conserved cysteine residues which form two
disulfide bonds, one of which is necessary for biological activity. It plays
an important role in inducing non-specific resistance against a broad range
of viral infections, and also affects cell proliferation and modulates immune
responses. IFNα-1a and IFNα-1b
are two forms of interferon alpha-1 except for the substitution of alanine
for valine at position 137. Interferon-alpha represents a group of related
but distinct proteins that share over 95% amino acid sequence homology.

保存条件:
-20℃或更低温度保存，至少一年有效。由于蛋白的每次冻融均会引起部分失活，所以**配制成相应浓度的储存液后(请根据产品简介中Reconstitution一栏的信息配制储存液)，须分装后-20℃或更低温度冻存，以避免反复冻融。
注意事项:
由于有些塑料管壁对某些蛋白有较强的吸附作用，溶液中的蛋白很容易粘附在管壁上，并且粘附后的蛋白很难与管壁分离。而载体蛋白(Carrier protein，如0.1% BSA等)的主要作用是预先封闭塑料管壁上的蛋白结合位点，使细胞因子或重组蛋白不会粘附于管壁。所以一定要使用产品简介中Reconstitution一栏的信息配制储存液。
