Protein Interaction Quantification Detection

Protein interaction quantitative detection refers to the quantification of interacting proteins. Biotech company Biotech Peptide provides protein interaction quantitative analysis services based on mass spectrometry, combining SILAC (Stable Isotope Labeling by Amino Acids in Cell Culture) with co-immunoprecipitation mass spectrometry, enabling both qualitative and quantitative analysis of interacting proteomes.

Protein Interaction Quantitative Detection

Protein-protein interactions involve highly specific physical contacts between two or more protein molecules, resulting from biochemical events controlled by electrostatic forces, hydrogen bonds, and hydrophobic effects. Nearly all cellular functions, including protein synthesis, maturation, and degradation, vesicle budding, transport, and fusion, receptor dimerization, signal cascades, gene regulation, metabolism, and catabolism, depend on and are executed by complex protein-protein interactions (PPIs). Protein interaction quantitative detection refers to the quantitative detection of interacting proteins. The process mainly includes screening, isolation, and quantitative analysis of interacting proteins. Various technical methods can be used for the quantitative analysis of interacting proteins, with SILAC and co-immunoprecipitation combined with mass spectrometry being highlighted here.

Protein Interaction Analysis Using SILAC and Co-Immunoprecipitation with Mass Spectrometry

Protein Interaction Quantitative Detection

SILAC (Stable Isotope Labeling by Amino Acids in Cell Culture) is a technique for stable isotope labeling under cell culture conditions and can be used in conjunction with mass spectrometry for quantitative proteomics analysis. Co-Immunoprecipitation (CoIP) is a classic method for studying protein interactions by using antibodies to specifically recognize particular antigens. The combination of SILAC, CoIP, and mass spectrometry can be used for high-throughput quantitative analysis of protein interaction networks under specific conditions.
