This Kit is based on competitive lateral flow immunochromatographic assay. The Natamycin-conjugate in the test zone will capture the immuno-gold (colloid gold-Natamycin antibody conjugate), when there is very little dissociative Natamycin in the samples. A visible red test line indicates a negative result when the control line (C line) shows that the card is valid. The test band (T line) will be not visible if Natamycin is present in concentration of 20 ppb and above which explains a positive result.
