Stem Cell Related Patent Number US6630327

Title:Methods and reagents for preparing and using immunological agents specific for P-glycoprotein
Inventors:Mechetner, Eugene; Irvine, CA, USA
Roninson, Igor B.; Wilmette, IL, USA
Summary:Described herein is an immunological reagent specific for P-glycoprotein, methods and uses thereof. The invention relates to immunological reagents and methods specific for a mammalian, transmembrane protein termed Pgp, having a non-specific efflux pump activity. Further disclosed are methods for developing and using immunological reagents specific for certain mutant forms of Pgp and for wild-type Pgp in a conformation associated with substrate binding or in the presence of ATP depleting agents. Claims of the invention include improved methods for purifying hematopoietic stems cells expressing Pgp. Therapeutic applications are included, such as in the detection of multi-drug resistant cancer, the isolation of hematopoietic cells and in therapies requiring selective cell killing.
Abstract:This invention relates to immunological reagents and methods specific for a mammalian, transmembrane protein termed Pgp, having a non-specific efflux pump activity established in the art as being a component of clinically-important multidrug resistance in cancer patients undergoing chemotherapy. The invention provides methods for developing and using immunological reagents specific for certain mutant forms of Pgp and for wild-type Pgp in a conformation associated with substrate binding or in the presence of ATP depleting agents. The invention also provides improved methods for purifying hematopoietic stems cells expressing Pgp and diagnostic and therapeutic methods for cancer cells expressing Pgp.
