3-(2-Furoyl)quinoline-2-carboxaldehyde is a neutral fluorogenic probe for amines for the picomolar assay of proteins by capillary electrophoresis (CE).[1][2]
A fast and improved sample preparation scheme was developed for protein analysis using capillary electrophoresis-sodium dodecyl sulfate (CE-SDS) with laser-induced fluorescence detection. This CE-SDS method was developed as a purity assay for recombinant monoclonal antibodies (rMAbs). In this assay, rMAbs
Carbonyl-modified proteins are markers of oxidative damage. Here, we report a new method for detecting and quantifying carbonylated proteins by capillary sieving electrophoresis (CSE) with LIF detection (CSE-LIF). Alexa 488 hydrazide is used for the specific labeling of carbonyls while

Fluorogenic reagents are used for protein labeling when high-sensitivity fluorescence detection is required. Similar to traditional labeling with activated fluorescent dyes, such as fluorescein isothiocyanate, a fluorogenic reaction is expected to change the physical-chemical properties of proteins. Knowledge of these
A quantitative method was developed for the direct identity confirmation and quantification of alendronate using CE-MS combined with a pH-assisted focusing technique, dynamic pH barrage junction focusing. A pH-induced variation in electrophoretic mobility led to online focusing of alendronate at
The composition of single MCF-7 breast cancer cells is characterized using 2-D CE. Individual MCF-7 cells were aspirated into a 30 mum inner diameter fused-silica capillary and lysed by contact with an SDS-containing buffer. Proteins and other primary amines were
