Application
This kit is for general cell membrane labeling. It has been characterized in a number of model systems and has been found to be useful for in vitro cell labeling, in vitro proliferation studies and short term, in vivo cell tracking. The half-life for elution of PKH2 from labeled rabbit red blood cells is 10-11 days. This slow elution may complicate interpretation of experiments assessing in vivo proliferation.
