General description

filtered through a 0.45 μm membrane filter

Application

Suitable as IEF-Marker for HPCE and for IEF-gels

Reconstitution

For use in HPCE the marker should be diluted 1:100 in a suitable ampholyte solution (e.g. 2% ampholyte 3-10), UV-detection at 280 nm (20 °C). For use in IEF-gels the solution can be loaded directly onto the gel (max. 1μl per lane).

We report capacitively coupled contactless conductivity detection (C4D) of proteins separated by microfluidic capillary isoelectric focusing (μCIEF). To elucidate the evolution of negative conductivity peaks during focusing and seek IEF conditions for sensitive conductivity detection, numerical simulation was performed using
