Proteomic analysis refers to the large-scale analysis of proteins in a particular biological sample under specific conditions. Methods used for proteomic analysis include mass spectrometry, 2D gel electrophoresis, and protein microarrays, which help researchers identify and quantify proteins, study their post-translational modifications, and understand their functions in organisms. CD BioSciences provides C. elegans proteomic analysis services to clients worldwide, helping you to gain a comprehensive understanding of the C. elegans proteome and unravel the complex mechanisms and interactions that underlie its biology.

Introduction to Proteomics in  C. elegans

As one of the excellent animal models, C. elegans is widely used in drug development and provides important insights for studies such as neurodegenerative diseases and metabolic syndrome. Because of its suitability for high-throughput screening, RNA interference, and the availability of thousands of mutants, most of the research on C. elegans has been conducted at the genetic level. However, in the post-genomic era, determining the cellular function of each gene product remains an unfinished goal. Mass spectrometry-based proteomics focusing on the actual gene products (i.e., proteins) can help researchers solve the puzzle.

C. elegans research utilizing forward or reverse genetic screening has focused primarily on genome-based approaches, and the proteins responsible for biological actions have been largely ignored. As instrumentation and technology continue to evolve, greater advances have been made in high-throughput proteomics analysis and data collection. For example, the introduction of dual-pressure linear ion trap mass spectrometers with higher sensitivity and faster cycle times has facilitated the detection and identification of proteins and unique peptides in the C. elegans proteome. For quantitative proteomics studies in cell cultures, Mann's group introduced "stable isotope labeling with amino acids in cell culture (SILAC)" in 2002.
