Abstract:
The electrophoresis method of the present invention employs a media which contains uniformly dispersed liposomes of phospholipid, or combinations of phospholipid and neutral lipid, which contain chromogenic materials or dye precursers. After electrophoresis of a test sample, the liposomes are lysed and the chromogen or dye material released. The chromogen or dye can be any signal producing substance including a chromogenic agent, and enzyme, a fluorogenic agent, or a chemiluminescent agent, but a detectable signal occurs only where the staining material is in close proximity to specific enzymes, effectors, analytes, or other color-inducing agents which have migrated through the gel during electrophoresis.
