Estrogen and Progestin Receptor Analysis in Human Breast Cancer by Isoelectric Focusing in Slabs of Polyacrylamide Gel
The use of estrogen- and progestin receptor-quantitation as prognostic indicators and for predicting response to endocrine treatment in individual cases of human breast cancer has created a need for convenient methods of receptor analysis. In our experience isoelectric focusing is an efficient method for routine analysis of estrogen receptors [8, 9] and progestin receptors  in surgical biopsies of human breast cancer.
