A method of characterizing a polypeptide comprising providing a first , capillary channel (104) having a separation buffer disposed within wherein , the separation buffer comprises a non-crosslinked polymer solution a , buffering agent, a detergent, and a lipophilic dye. The separation buffer is provided such that, at the time of detection the detergent concentration in , the buffer is not above the critical micelle concentration. The polypeptide is introduced into one end of the capillary channel. An electric field is applied across the polymer solution at different rates. The polypeptide is then detected as it passes a point (176) along the length of the capillary channel.

Why it's free to use
- Filed February 2, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 2, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 2, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
