Description
Boster’s human TFPI ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A polyclonal antibody from goat specific for TFPI has been precoated onto 96-well plates. Standards(NSO, D29-K282) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for TFPI is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human TFPI amount of sample captured in plate.

Reproducibility
To assay reproducibility, three samples with differing target protein concentrations were assayed using four different lots.
