General Description：
Tumor necrosis factor alpha (TNF-α),also called cachectin,is the best-know member of the TNF-family,which can cause cell death.This protein is produced by neutrophils,activated lymphocytes,macrophages,NK cells,LAK cells,astrocytes endothelial cells,smooth muscle cells and some transformed cells.TNF-α occurs as a secreted,soluble form and as a membrane-anchored form,both of which are biologically active.The naturally-occurring form of TNF-α is glycosylated,but non-glycosylated recombinant TNF-α has comparable biological activity.The biologically active native form of TNF-αis reportedly a trimer.Human and murine TNF-α show approximately 79% homology at the amino acid level and cross-reactivity between the two species.Two types of receptors for TNF-α have been described and virtually all cell types studied show the presence of one or both of these receptor types.
Storage：
This lyophilized preparation is stable at 2～8℃,but should be kept at -20℃ for long term storage,preferably desiccated.Upon reconstitution,the preparation is stable for up to one week at 2～8℃.For maximal stability,apportion the reconstituted preparation into working aliquots and store at -20℃ to -70℃.Avoid repeated freeze/thaw cycles.
Usage：
This material is offered by Biorab Biotech for research,laboratory or further evaluation purposes.
NOT FOR HUMAN USE.
Molecular Weight：
Approximately 17.4kDa.The recombinant murine TNF-α is a soluble 157 amino acid protein which corresponds to C-terminal extracellular domain of the full length transmembrane protein.
Purity：
> 98% by SDS-PAGE and HPLC analyses.
Source：
Escherichia coli.
Biological Activity：
Fully biologically active when compared to standard.The ED50 as determined by a cytotoxicity assay using murine L929 cells is less than 0.1ng/mL,corresponding to a specific activity of> 1.0×107 IU/mg in the presence of actinomycin D.
Physical Appearance：
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation：
Lyophilized from a 0.2μm filtered solution in PBS,pH7.2.
Endotoxin：
Less than 1 EU/μg of rMuTNF-α 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.
