Abstract
A device for separating one or more components in a sample is disclosed, the device including: (a) a first planar member (1) having a channel (2) along which a sample may be loaded and component(s) thereof focussed isoelectrically; and (b) means for exposing the channel (2) along at least a portion of its length and thereby exposing the sample or component(s) therewithin. The means for exposing the channel (2) may include a cover plate (7). A method of analysing a molecule is also provided, the method including: (a) providing an elongate open channel (2); (b) introducing a plurality of molecules into the elongate open channel (2); (c) separating molecules along the elongate open channel (2) according to their isoelectric points; (d) accessing a molecule in the elongate open channel (2) and analysing it. A use of the device in combination with a mass spectrometer, preferably a MALDI-TOF unit, for analysis of a protein is also disclosed.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
