Figure 7From: An ELISA-based procedure for assaying proteins in digests of human leukocytes and cell lines, using specifically selected peptides and appropriate antibodiesDetection of the proteins MRP 1 and MXR. Panel A and B show an experiment detecting the protein MRP1 in wild type and transformed MCF7 cells, using the MRP P1 peptide and one of the specific antisera. Again a calibration curve and a calculated peptide amount vs. cell amount are shown. In panel C an experiment detecting the MXR protein in wild type and transformed MCF7 cells is shown. Similarly to Figure 3A we have marked the readings of wt and resistant cell digests with a solid and an empty triangle respectively.Back to article page
