Cell staining system for flow cytometry

摘要

A pipetting system is provided which includes 1) a microtiter plate, 2) a multichannel pipette, and 3) a rack for recieving the microtiter plate and the multichannel pipette. The rack includes multiple rows corresponding to the rows of the microtiter plate. The rack and the multichannel pipette are constructed so that for each row, the pipette can be inserted in the rack in only one left/right orientation. In this way, errors due to misorientations of the pipette with the wells of the microtiter plate are eliminated. Methods for staining cells for flow cytometry using the pipetting system are also disclosed.
