Beschreibung
Zusammenfassung:	The present inventions relate to micro-fluidic devices and related methods of fractionating samples of analytes, such as peptides or proteins, according to their isoelectric points. The disclosed micro-fluidic devices and related methods provide a fractionation sufficient to enhance the performance of immunochemistry and/or tandem liquid chromatography-mass spectrometry workflows. Such methods and devices are capable of fractionating complex samples in a short time, using a small amount of sample, do not require high voltages and are further characterized by their high degree of reproducibility and ease of use.
