1 To quantify the expression of the gene encoding P-gp (multidrug resistance 1; MDR1) and assess P-gp function, we developed competitive reverse transcription-polymerase chain reaction (RT-PCR) assay using heterologous competitor RNA and flow cytometric analysis using rhodamine 123 (Rh123; an artificial substrate for P-gp), respectively. Rhodamine 123 ATP binding cassette subfamily B member 1 Homo sapiens

4 The MDR1 expression in leukemia sublines quantified by competitive RT-PCR assay showed linearity over a wide range, and the results were parallel with those of MDR1 expression measured by Northern blot analysis, the P-gp antigen expression measured by flow cytometric analysis using MRK16, P-gp function analysis by Rh123 dye-efflux assay, and MDR phenotype. Rhodamine 123 ATP binding cassette subfamily B member 1 Homo sapiens
