About this Protein
Name
Recombinant Canine IFN-γ (Recombinant Canine Interferon-γ; rCaIFN-γ)；重組狗干擾素γ
Synonyms
IFNG; IFG; IFI; IFN-gamma; Immune interferon; interferon gamma; interferon, gamma
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 A-72 canine fibroma cells infected with vesicular stomatitis virus (VSV) is less than 2.0ng/ml, corresponding to a specific activity of >5.0×105IU/mg.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μm filtered concentrated solution in 25mM Sodium Succinate, pH5.0, 60mM NaCl, with 0.1% Tween-80.
Endotoxin
Less than 0.1EU/μg of rCaIFN-γ 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-gamma (IFN-γ), also known as Type II interferon or immune interferon, is a cytokine produced primarily by Tlymphocytes and natural killer cells. The protein shares no significant homology with IFN-β or the various IFN-α family proteins. Mature IFN-γ exists as noncovalently-linked homodimers. IFN-γ was originally characterized based on its antiviral activities. The protein also exerts antiproliferative, immunoregulatory and proinflammatory activities and is thus important in host defense mechanisms. IFN-γ induces the production of cytokines, upregulates the expression of class I and II MHC antigens, Fc receptor and leukocyte adhesion molecules. It modulates macrophage effector functions, influences isotype switching and potentiates the secretion of immunoglobulins by B cells. Additionally, IFN-γ augments TH1 cell expansion and may be required for TH1 cell differentiation. Canine IFN-γ shares 79%~88% amino acid sequence identity with bovine, equine and feline IFN-γ, 62%~73% with human, porcine and rhesus macaque IFN-γ, and 40%~47% with cotton rat, murine and rat IFN-γ.

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(yīng)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(fù)凍融。 注意事項: 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，使細(xì)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(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，請穿實驗服并戴一次性手套操作。
