>MABSol® Biotin Labeled Proteins
>Biotinylated Human TNF-alpha Protein
This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™) The protein has a calculated MW of 19.2 kDa. The protein migrates as 21 kDa on a SDS-PAGE gel under reducing (R) condition due to glycosylation. More than 95% of Biotinylated Human TNF-alpha (TNA-H82E3) presents as active trimers with a molecular mass of 57 kDa, as determined by SEC-HPLC analysis.
>95% as determined by SDS-PAGE.
>95% as determined by SEC-HPLC.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

No activity loss is observed after storage at:
Biotinylated Human TNF-alpha (HPLC-verified) on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
Over 95% of Biotinylated Human TNF-alpha (TNA-H82E3) presents as active trimers with a molecular mass of 57 kDa, as determined by SEC-HPLC analysis.
Recombinant Human TNF-alpha (Cat.No. TNA-H82E3) induces cytotoxicity effect on the WEH1-13VAR cells in the presence of the metabolic inhibitor actinomycin D. The EC50 for this effect is 0.029-0.052ng/ml (Routinely tested).
Neutralization assay shows that the cytotoxicity effect of TNF-alpha (Cat.No. TNA-H82E3) was inhibited by increasing concentration of Adalimumab. The concentration of TNF-alpha used is 1ng/mL. The IC50 is 7ng/mL (Routinely tested).
