For flow cytometry and Western blotting dilutions to be used depend on detection system applied. It is recommended that users test the reagent and determine their own optimal dilutions. The typical starting working dilution is 1:10. For neutralization of biological activity dilutions have to be made according to the amounts TNF-alpha to be inactivated. Before use in biological assays, the product must be filter sterilized and depending on the concentration to be used dialyzed against culture medium to remove the sodium azide added. Please inquire for availability of azide free solutions.
The antibody reacts with human natural and recombinant TNF-alpha as assessed by ELISA. The antibody inhibits the biological activity of human natural and recombinant TNF-alpha as determined with L929 and WEHI cells in a cytotoxicity assay. The antibody cross reacts with rhesus and cynomolgus natural TNF- alpha and lacks cross reactivity with human lymphotoxin.
