Abstract
This invention relates to devices and methods for purifying, detecting and using biological cells. A variety of cell types including viable tumor, stem, immune and sperm cells can be purified from a complex biological sample using a column, including a pipette tip column. Methods of the invention can aid research, diagnosis and treatment of cancer. Purified viable cells can be detected on the column or eluted from the column and detected. Cells on a column can be used as a stationary phase for liquid chromatography. Cells may be removed, recovered and analyzed.
