PNA ELISA kit is a competitive enzyme immunoassay for the quantitative analysis of PNA in peanut,soybean samples.
The coupling antigens are coated on the micro-well stripes. The PNA in the sample and the coupling antigens coated on the micro-well stripes compete for the anti-PNA antibodies. After the addition of the enzyme conjugate, the TMB substrate is added for coloration.
The optical density (OD) value of the sample has a negative correlation with the PNA in it. The measurement is made photometrically at 450 nm. The absorption is inversely proportional to the PNA concentration in the sample.
Detect Limit: 0.50 ppb
Specification: 96 tests/kit
