Standardization of steroid receptor assays in human breast cancer--II. Samples with low receptor content.

Abstract

Four different lyophilized cytosols with low receptor content were assayed for estrogen and progesterone receptors by 13 laboratories in 7 countries. Each sample was analyzed on three different working days. Three laboratories reported unsatisfactory ER results, whereas the other 10 participants were in good agreement. Employing a cut-off limit of 10 fmol… (More)
