About this Antibody
Name
Recombinant Human IFN-λ1/IL-29 (Recombinant Human Interferonλ1/Interleukin-29; rHuIFN-λ1/IL-29)；重組人干擾素1/白細胞介素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(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(jié)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(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。
