Synonyms
IFL; IFN; IFNA; IFNA13; IFN-ALPHA; IFN-alphaD
Purity
>96% by SDS-PAGE and HPLC analyses.
Biological Activity
Fully biologically active when compared to standard. The specific activity determined by an anti-viral assay is no less than 1.0×108IU/mg.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μm filtered solution in PBS, pH7.4, containing 4% mannitol and 1% HSA.
Endotoxin
Less than 1EU/μg of rHuIFN-α1b 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 0.1-1.0mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤-20℃. Further dilutions should be made in appropriate buffered solutions.
Category
Cytokine
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。 本产品**于专业人员的科学研究用，不得用于临床诊断或**，不得用于食品或药品，不得存放于普通住宅内。 为了您的**和健康，请穿实验服并戴一次性手套操作。
