简单介绍
Recombinant Human IFN-λ1/IL-29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-λ1/IL-29所以一定要使用产品简介中Reconstitution一栏的信息配制储存液。

About this Antibody

Name

Recombinant Human IFN-λ1/IL-29 (Recombinant Human Interferonλ1/Interleukin-29; rHuIFN-λ1/IL-29);重组人干扰素1/白细胞介素29

Synonyms

IFN-lambda 1; cytokine Zcyto21; IFNL1; IFN-lambda-1; IL-29; interferon lambda-1; interferon, lambda 1; interleukin 29 (interferon, lambda 1); interleukin-29; ZCYTO21

Purity

>97% by SDS-PAGE and HPLC analyses.

Biological Activity

Fully biologically active when compared to standard. The ED50 as determined by an anti-viral assay using human HepG2 cells infected with encephalomyocarditis is less than 5ng/ml, corresponding to a specific activity of >2.0×105IU/mg.

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Formulation

Lyophilized from a 0.2μM filtered concentrated solution in PBS, pH7.4.

Endotoxin

Less than 1EU/μg of rHuIFN-λ1/IL-29 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.

Cytokine

Background

IL-28A, IL-28B, and IL-29, also named interferon-λ2 (IFN-λ2), IFN-λ3, and IFN-λ1, respectively, are newly identified class II cytokine receptor ligands that are distantly related to members of the IL-10 family (11-13%a.a. sequence identity) and the type I IFN family (15-19%a.a. sequence identity). The expression of IL-28A, B, and IL-29 is induced by virus infection or doublestranded RNA. All three cytokines exert bioactivities that overlap those of type I IFNs, including antiviral activity and upregulation of MHC class I antigen expression. The three proteins signal through the same heterodimeric receptor complex that is composed of the IL-10 receptor β (IL-10 Rβ) and a novel IL-28 receptor α (IL-28 Rα, also known as IFN-λR1). Ligand binding to the receptor complex induces Jak kinase activation and STAT1 and STAT2 tyrosine phosphorylation.

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)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。
