Measuring IgG anti-A/B titres using dithiothreitol (DTT).

Abstract

In comparing the use of the sulphydryl compounds 2-mercaptoethanol (2ME) and dithiothreitol (DTT) a rapid one-stage technique for titrating IgG anti-A and anti-B using DTT in an antiglobulin test was tried. The results correlated well with those obtained by either of the two-stage methods using 2ME or DTT.
