Protein fingerprinting of Staphylococcus aureus by capillary electrophoresis with on-capillary derivatization and laser-induced fluorescence detection.

Cristina Pelaez-Lorenzo et al.

Methods in molecular biology (Clifton, N.J.), 984, 237-251 (2013-02-07)

This chapter describes a complete procedure for obtaining protein fingerprints of microorganisms using capillary electrophoresis (CE) with laser-induced fluorescence detection (LIF). Staphylococcus aureus, a human pathogen responsible of frequent and resistant infections, is used as model microorganism to show the

Protein fingerprinting of Staphylococcus species by capillary electrophoresis with on-capillary derivatization and laser-induced fluorescence detection.

Maria Teresa Veledo et al.

Analytica chimica acta, 658(1), 81-86 (2010-01-20)

Capillary electrophoresis (CE) coupled with laser-induced fluorescence detection (LIF) has allowed to obtain protein fingerprints, which have demonstrated to be useful in microorganisms characterization. In this work, protein fingerprints of two species of Staphylococcus grown in different culture media and

Solid-phase fluorescent labeling reaction of picomole amounts of insulin in very dilute solutions and their analysis by capillary electrophoresis.

D M Pinto et al.

Electrophoresis, 16(4), 534-540 (1995-04-01)

The fluorescent labeling of peptides at concentrations as low as 10(-8) M can be achieved by using a solid-phase reactor. Using oxidized insulin chain B as a test peptide, we demonstrate the use of an Immobilon CD membrane to capture

Instrumentation for medium-throughput two-dimensional capillary electrophoresis with laser-induced fluorescence detection.

Cuiru Zhu et al.

Analytical chemistry, 79(2), 765-768 (2007-01-16)

In two-dimensional capillary electrophoresis, a sample undergoes separation in the first dimension capillary by sieving electrophoresis. Fractions are periodically transferred across an interface into a second dimension capillary, where components are further resolved by micellar electrokinetic capillary electrophoresis. Previous instruments

Sodium dodecyl sulfate-capillary electrophoresis of proteins in a sieving matrix utilizing two-spectral channel laser-induced fluorescence detection.

D B Craig et al.

Electrophoresis, 19(12), 2175-2178 (1998-10-07)

We report a method for protein labeling, separation by capillary electrophoresis in a polymer sieving matrix, and detection by laser-induced fluorescence. Different dyes are used to label standard and sample proteins. A two-spectral channel detector resolves fluorescence from the sample
