- 应用备注
- ELISA Standard: Recombinant human TNF is useful as a quantitative standard for measuring human TNF protein levels in a TNF specific sandwich ELISA with the purified MAb1 antibody (Cat. No. 551220) as a capture antibody and the biotinylated MAb11 antibody (Cat. No. 554511) as the detection antibody. To obtain linear standard curves, doubling dilutions of this human TNF standard from 2000-15 pg/ml should be included in each ELISA plate. These ELISA reagents are not recommended for assay of serum samples. For testing TNF in serum or plasma, the human TNF BD OptEIA™ Set (Cat. No. 555212) and the human TNF BD OptEIA Kit (Cat. No. 550610) are specially formulated and recommended.
