Proteomics is the largescale study of proteins, their structures, functions, and interactions.
Protein extraction, purification, separation, identification, quantification, and bioinformatics are some of the methods used in proteomics.
Proteomics has made significant contributions to unraveling the complexity of biological systems, drug discovery, precision medicine, and personalized nutrition.
Proteomics has led to the identification of new biomarkers for cancer diagnosis, prognosis, and drug development.
Proteomics can be used to improve crop yield, quality, and resistance to environmental stresses.
Proteomics has provided insights into the underlying mechanisms of Alzheimer's, Parkinson's, and other neurodegenerative diseases.
Proteomics allows the analysis of thousands of proteins at once, which is not possible with traditional methods.
Proteomics can identify modifications that occur after proteins are synthesized, such as phosphorylation, acetylation, and glycosylation.
Proteomics can measure the relative abundance of proteins under different conditions, which is essential for understanding biological processes.
Mass Spectrometry
2D Gel Electrophoresis
Protein Microarrays
Mass spectrometry is the most widely used technique in proteomics and can identify and quantify proteins in complex mixtures.
2D gel electrophoresis separates proteins based on their isoelectric point and molecular weight.
Protein microarrays allow the screening of thousands of proteins for interactions with other molecules.
1 Target Identification
Proteomics can be used to screen large libraries of compounds for their ability to bind to proteins of interest.
Proteomics can identify potential drug targets based on their expression and activity levels in disease compared to normal tissue.
3 Pharmacodynamic Biomarkers
Proteomics can identify biomarkers that indicate dosing, efficacy, and toxicity of drugs in clinical trials.
Dynamic Range
The concentration of proteins in biological samples spans many orders of magnitude, which can make it difficult to detect lowabundance proteins.
Post-translational modifications can affect protein function and localization and can be difficult to detect and quantify.
Proteomics experiments can be highly variable due to differences in sample preparation, instrumentation, and data analysis.
Artificial Intelligence
Spatial Mapping
AI algorithms are being developed to help analyze large proteomics datasets and predict protein structure and function.
New techniques are being developed to map the location of proteins within cells and tissues to better understand their function.
New technologies are emerging to analyze the proteome of individual cells, which can provide insights into cell development and disease.
