About this Protein | |
Name | Recombinant Human IFN-α1a (Recombinant Human Interferon-α1a; rHuIFN-α1a);重組人干擾素α1a |
Synonyms | IFL; IFN; IFNA; IFNA13; IFN-ALPHA; IFN-alphaD |
Purity | >97% 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 lyophilized (freeze-dried) liquid-like powder. |
Formulation | Lyophilized from a 0.2μm filtered solution in PBS, pH7.4, containing 3% Mannitol, 5% Trehalose, 0.05% Tween-80. |
Endotoxin | Less than 0.1EU/μg of rHuIFN-α1a 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,所以首次配制成相應(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)品在凍干時添加了海藻糖作為保護(hù)劑,此時凍干后本產(chǎn)品看起來仍然像是液體,屬于正?,F(xiàn)象。在凍干工藝上,海藻糖作為常用的凍干保護(hù)劑,可顯著阻止蛋白質(zhì)二級結(jié)構(gòu)的改變,防止凍干過程中的蛋白變性。
???????本產(chǎn)品僅限于專業(yè)人員的科學(xué)研究用,不得用于臨床診斷或治療,不得用于食品或藥品,不得存放于普通住宅內(nèi)。
???????為了您的安全和健康,請穿實驗服并戴一次性手套操作。
