Human IFNA7 HEK293 Overexpression Lysate: 产品信息

产品描述
This Human IFNA7 overexpression lysate was created in HEK293 Cells and intented for use as a Western blot (WB) positive control. Purification of IFNA7 protein (Cat: 10341-H01H) from the overexpression lysate was verified.
表达宿主

Human
蛋白构建信息
A DNA sequence encoding the human IFNA7 (P01567) (Cys 24-Asp 189) was fused with the Fc region of human IgG1 at the N-terminus.
分子量
The recombinant human IFNA7/Fc chimera is a disulfide-linked homodimer. The reduced monomer comprises 427 amino acids with a predicted molecular mass of 48 kDa. rh IFNA7/Fc monomer migrates as an approximately 50 kDa band in SDS-PAGE under reducing conditions.

Human IFNA7 HEK293 Overexpression Lysate: 使用指南

制备方法
Cell lysate was prepared by homogenization of the over-expressed cells in ice-cold modified RIPA Lysis Buffer with cocktail of protease inhibitors (Sigma). Cell debris was removed by centrifugation. Protein concentration was determined by Bradford assay (Bio-Rad protein assay, Microplate Standard assay). The cell lysate was boiled for 5 min in 1 x SDS loading buffer (50 mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.
裂解缓冲液
Modified RIPA Lysis Buffer: 50 mM Tris-HCl pH 7.4, 150 mM NaCl, 1mM EDTA, 1% Triton X-100, 0.1% SDS, 1% Sodium deoxycholate, 1mM PMSF.
使用建议
1.  Centrifuge the tube for a few seconds and ensure the pellet at the bottom of the tube. 2.  Re-dissolve the pellet using 200μL pure water and boil for 2-5 min.
缓冲液
1 X Sample Buffer (1 X modified RIPA buffer+1 X SDS loading buffer).
稳定性 & 储存条件
Store at 4℃ for up to twelve months from date of receipt. After re-dissolution, aliquot and store at -80℃ for up to twelve months. Avoid repeated freeze-thaw cycles.
应用
Western Blot (WB)
Optimal dilutions/concentrations should be determined by the end user.

IFNA7 背景信息

Interferon alpha-7(IFNA7) is a member of the interferon family. Interferons belong to the group of the regulatory glycoproteins, of low molecular mass. They are the products of infected cell-genome, but not virus, as a consequence of the cause answer by different inductors. Interferon stimulates the production of two enzymes: a protein kinase and an oligoadenylate synthetase. They allow communication between cells to trigger the protective defenses of the immune system that eradicate pathogens or tumors. IFNs have other functions: they activate immune cells, such as natural killer cells and macrophages; they increase recognition of infection or tumor cells by up-regulating antigen presentation to T lymphocytes, and they increase the ability of uninfected host cells to resist new infection by the virus. Certain host symptoms, such as aching muscles and fever, are related to the production of IFNs during infection. Human IFN is divided on the sequence of amino-acids into three groups: Alpha, Beta, and Gamma interferons.
