The bridge length effect on sensitivity in steroid enzyme immunoassay.

The effect of the bridge heterologous combination between antiserum and enzyme-labeled antigen on sensitivity in 11-deoxycortisol enzyme immunoassay has been investigated. The sensitivity of an assay system using a β-galactosidase-labeled antigen prepared from an 11-deoxycortisol derivative having a carboxymethylthio moiety as a bridge at C-4 was compared with one with an N-(carboxymethyl) carbamoylmethylthio moiety at C-4. The former assay proved to be more sensitive than the latter. This indicates that the bridge length is an important factor influencing the sensitivity of hapten enzyme immunoassay.
