27, WP:JW9, ABSTRACT, A method for isolating a cDNA specific for P-glycoprotein is disclosed. The P-glycoprotein is the determinant in the multidrug resistance phenotype exhibited by living cells. The nucleic acid equivalent of the cDNA may be cloned in a recombinant plasmid or phage. The cDNA may also be used as a probe in determining multidrug resistance in cells. The DNA molecules specific for the P-glycoprotein is in the form of a gene family where various members of the gene family are amplified to varying degrees in multidrug resistant cells from various sources.
