About this Antibody
Name
Recombinant Murine IFN-λ2/IL-28A (Recombinant Murine Interferon-λ2/Interleukin-28A; rMuIFN-λ2/IL-28A)；Recombinant Mouse IFN-λ2/IL-28A ; 重組小鼠干擾素λ2/白細(xì)胞介素28A
Synonyms
IFN-lambda 2; interleukin-28A; IL28A; IL-28A; interferon, lambda 2
Purity
>95% 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 3ng/ml, corresponding to a specific activity of >3.3×105IU/mg.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH7.4, with 5% trehalose.
Endotoxin
Less than 0.1EU/μg of rMuIFN-λ2/IL-28A 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 lambda-2, as known as IL-28A, belongs to the lambda interferon family. IL-28A (IFN-λ2), IL-28B (IFN-λ3) and IL-29 (IFN-λ1) are type III interferons that are class II cytokine receptor ligands. These IFNs signal through a receptor complex consisting of IL10R2 (also called CRF2-4) and IFNLR1 (also called CRF2-12). Interferon lambda-2 displays potent antiviral activity and antitumor activity, so it plays a significant role in the antiviral immune defense in the intestinal epithelium. It also upregulate MHC class I antigen expression. Recombinant murine interferon lambda-2 contains 174 amino acids and it shares 81% and 66%a.a. sequence identity with rat and human IFN-λ2, respectively, and functions across species.

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(huì)引起部分失活，所以**配制成相應(yīng)濃度的儲(chǔ)存液后(請根據(jù)產(chǎn)品簡介中Reconstitution一欄的信息配制儲(chǔ)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(xiàng): 由于有些塑料管壁對某些蛋白有較強(qiáng)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(diǎn)，使細(xì)胞因子或重組蛋白不會(huì)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(chǔ)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(shí)驗(yàn)服并戴一次性手套操作。
