Chlorophenols assay

PAbs against 2,4,5-TCP have been prepared after theoretical and molecular modeling chemical studies [226]. Competitive direct and indirect ELIS As have been developed, but as before the latter format was shown to be more robust. The indirect immunoassay has an excellent LOD near 0.05 pg L . The selectivity of the assay is high in relation to other chlorophenols frequently present in real samples, but as with the 2,4,6-TCP assay the brominated analogs may also be recognized. The 2,4,5-TCP immunoassay is stable in media with pH...

A modification of the acylneuraminate pyruvate-lyase assay using pyruvate oxidase to generate H2O2, and measurement of this with peroxidase and p-chlorophenol-4-aminoantipyrine has been described (Sugahara et al. 1980). The measurement of the chromophore is at 505 nm and a molar extinction coefficient of 1.14 X 104 was found at this wavelength. This test has been used in conjunction with sialidase for estimation of serum sialic acid (Sugahara et al. 1980), but remains less sensitive than the method coupled with lactate dehydrogenase.
