Sequencing of Proteins from the C-Terminusdetect that residue when it is present in one nanomole of a protein sample. On average, it is possible to sequence 5 cycles on one nanomole of protein applied to polyvinylidene difluoride (PVDF) membrane if the amino acid sequence contains those residues listed in the “reliably called” column of Tab

Tandem Mass Spectrometric Characterization of Modified Peptides and Proteinsdem MS of peptides using four-sector mass spectrometers generally involves high energy collisional activation of precursor ions (usually [M+H].) to promote fragmentations indicative of sequence and permitting the differentiation of isomeric/isobaric amino acid residues [1].

Direct Mass Spectrometric Analyses for Protein Chemistry StudiesMass spectrometry is a sensitive bioanalytical method (McCloskey, 1990), but it is often difficult for the method to selectively discriminate against . species found in a sample, in search of the few components the scientist is truly interested. MS analysis of a sample containing a small amount of p

Peptide-Mass Fingerprinting as a Tool for the Rapid Identification and Mapping of Cellular Proteinsificant analytical challenges. The recent introduction of matrix-assisted laser-desorption (MALD) time-of-flight mass spectrometers (Karas and Hillenkamp, 1988) has led to the rapid analysis (at high sensitivity) of peptide mixtures. New strategies have been developed using a combination of protease

Characterization of Proteins Separated by Gel Electrophoresis at the Primary Structure Leveln the focus on complex, highly regulated systems consisting of numerous interacting elements. A complete understanding of such processes can only be achieved if the problem is approached globally, considering the temporal and spatial interactions of all the elements involved. This task is supported

New Strategies in High Sensitivity Characterization of Proteins Separated from 1-D or 2-D Gelsom very complex mixtures (O’Farrell, 1975; Celis & Bravo, 1984). For structural analysis, proteins are electrotransferred from the gels onto immobilizing membranes for subsequent NH.-terminal sequence analysis (Vandekerckhove .., 1985; Aebersold .., 1986; Matsudaira, 1987). Alternatively, proteins c

Pre-Electrophoretic Labelling of Proteins with a Coloured Water Soluble Edman Reagentof proteins. However, it is generally used as an analytical rather than a preparative tool. With the advent of PVDF membranes which are stable under the conditions employed by the Edman degradation, it has become common to try and obtain N-terminal sequence data from proteins separated by SDS PAGE f
