About this Antibody
Name
Recombinant Rat TNF-α/TNFSF2 (Recombinant Rat Tumor Necrosis Factor-α; rRtTNF-α)；重組大鼠腫瘤壞死因子α
Synonyms
Cachetin; DIF; TNF; tnfa; tnf-a; TNFSF1A; TNFSF2; APC1 protein; Cachectin; DIF; TNF, monocyte-derived; TNF-a; TNF-alphacachectin; TNFATNF, macrophage-derived; TNFSF2TNF superfamily, member 2; tumor necrosis factor; tumor necrosis factor (TNF superfamily, member 2); tumor necrosis factor alpha; Tumor necrosis factor ligand superfamily member 2; tumor necrosis factor-alpha
Purity
>98% by SDS-PAGE and HPLC analyses.
Biological Activity
Fully biologically active when compared to standard. The ED50 as determined by a cytotoxicity assay using murine L929 cells is less than 0.05ng/ml, corresponding to a specific activity of >2.0×107IU/mg in the presence of actinomycin D.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μm filtered concentrated solution in 20mM PB, pH7.2, 150mM NaCl.
Endotoxin
Less than 1EU/μg of rRtTNF-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.

Background
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-glycosylatedrecombinant TNF-α has comparable biological activity. 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.

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**配制成相應濃度的儲存液后(請根據產品簡介中Reconstitution一欄的信息配制儲存液)，須分裝后-20℃或更低溫度凍存，以避免反復凍融。 注意事項: 由于有些塑料管壁對某些蛋白有較強的吸附作用，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)的主要作用是預先封閉塑料管壁上的蛋白結合位點，使細胞因子或重組蛋白不會粘附于管壁。所以一定要使用產品簡介中Reconstitution一欄的信息配制儲存液。 本產品**于專業(yè)人員的科學研究用，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。 為了您的**和健康，請穿實驗服并戴一次性手套操作。
