Method Principle
Albumin gradient more active Y cells readily migrate into viscous solutions Sephadex filtration heavier X cells are eluted from the column first Electrophoresis negatively-charged X cells migrate rapidly toward the anode Flow cytometry fluorescent sorting of fluorochrome-labeled DNA (eg., Y chromatin-quinacrine) Immunoaffinity chromatography selectively bind cells to antibody attached to a solid support, then elute
