Capillary isoelectric focusing with whole-column imaging detection (icIEF) technology is now
the mainstream technology to perform analytical isoelectric focusing analysis in …

This review is in support of the development of selective, precise, fast, and validated
capillary electrophoresis (CE) methods. It follows up a similar article from 1998, Wätzig H …

We report a new online capillary isoelectric focusing-mass spectrometry (CIEF-MS) method
for monoclonal antibody (mAb) charge variant analysis using an electrokinetically pumped …

A new highly sensitive microscaleanalytical procedure called affinity probe capillary
electrophoresis (APCE) ispresented. One of the two species, which can form a biospecific …

Capillary isoelectric focusing (CIEF) provides excellent resolution of proteins with the
advantage that separations are carried out in a capillary format with on‐tube detection and …

In order to contribute to the scientific research on the severe acute respiratory syndrome
coronavirus 2 (SARS‐CoV‐2), we have investigated the isoelectric points (pI) of several …

The feasibility of isoelectric focusing (IEF) performed on-chip was demonstrated for the first
time via absorption imaging detection. Microchannels on a quartz chip were fabricated using …

Biopharmaceuticals are increasingly present in pharmaceutical therapy. These highly
complex molecules are still challenging for development and quality control. Charge …

Whole column imaging detection has been developed for capillary isoelectric focusing
(CIEF) of proteins and peptides. In this imaged CIEF technique, a solution of sample and …

The methodological advancements in CIEF in tubes and microchips during the period
between 2002 and early 2008 are reviewed as a continuation of previous review by the …
