Proteomic Analysis of Human Neutrophils
Part of the
Methods in Molecular Biology™
book series (MIMB, volume 332)
Proteomics is the study of the set of proteins, or proteome, expressed by a cell under specific conditions. Proteomics methodology consists of protein extraction, protein separation, and protein identification. Currently, two-dimensional gel electrophoresis (2DE) and matrix-assisted laser-desorption ionization time of flight mass spectrometry are the most widespread methods for proteomic studies. The recent introduction of precast immobilized pH gradient gel strips, precast gradient sodium dodecyl sulfate-polyacrylamide gel electrophoresis gels, and well-designed electrophoresis equipment has made 2DE a highly reproducible and relatively simple method for protein separation. Inherent limitations of the procedure, however, require approaches in sample preparation that may be cell- or tissue-dependent. This chapter describes a methodology for proteomic analysis of human neutrophils and discusses its applications.
