Abstract: A novel technique was developed, that was high throughput simultaneousscreening of multiple resistance protein expression based on a protein array system. Themethod combined the advantage of the specificity of enzyme-linked immunosorbentassays with the sensitivity and high throughput of microspot. In this system, the multipleresistance protein arrays were created by spotting the captured antibodies onto the glassslide. The arrays were then incubated with cell samples of leukemia patients. The boundproteins were recognized by biotin-conjugated antibodies and detected by CCD.Experiments demonstrated that three multiple resistance proteins, including Pgp, MRPand BCRP which are members of the ATP-binding-cassette (ABC) superfamily ofmembrane transporters could be simultaneously detected using this new approach.Research work shows the result is coincident with flow cytometry (FCM) (P>0.01). Itprovided a methodology to develop many high-density protein array systems to detect avariety of proteins. The protein arrays will provide a powerful tool to identify theleukemia cell protein expression and rapidly validate their MDR determination.
