| 20110210000 | Isoelectric particles and uses therefore - A plurality of particles of from about 5 nm to 100 μm possessing predetermined isoelectric points in the pH range of from about 2.5 to 11 is used in a method of detection of a plurality of analytes, wherein the isoelectric particles of each isoelectric point further contain as label and a member of a binding pair capable of interacting with a selected analyte. The particles that form specific binding pairs are recovered and separated by isoelectric focusing followed by the detection of the labels associated with the particles. A flow cytometer may be used as a detector of the isoelectric particles. | 09-01-2011 |
