Proteomics Analysis Service

The term "proteomics" is the combination of "protein" and "genomics", referring to the full set of proteins expressed by a genome, which consists of all the proteins expressed by a cell or an organism. In 1995 (though there are mentions of 1994 and 1996), Marc Wilkins first proposed the concept of proteome, and in 1997, Peter James (who worked at the Swiss Federal Institute of Technology, known as the European MIT) further introduced the concept of proteomics. The concepts of genomics and proteomics have further given rise to various other omics, and their birth and development have also made systematic biology possible. MtoZ Biolabs provides integrate Proteomics Analysis Service.

Research on proteome not only provides a material basis for understanding the laws of life activities but also offers theoretical basis and solutions for elucidating numerous disease mechanisms. By comparing the proteome of normal and pathological individuals, we can identify certain disease-specific protein molecules, which may serve as molecular targets for new drug design, or may also provide molecular markers for early disease diagnosis. Indeed, some of the best-selling drugs worldwide are either proteins or target-specific protein. Thus, proteomics research is not only essential for exploring the mysteries of life but also benificial to human health. The study of proteomics is a characteristic of life sciences entering the post-genomic era.

Proteomics refers to the systematic identification and quantification of the proteome of a biological system (cell, tissue, organ, body fluid, or organism) at a specific time point. Mass spectrometry (MS) is the most commonly used technique for proteomics. MtoZ Biolabs, based on high-throughput mass spectrometry technology, has established many proteomics analysis platforms, possessing first-class MS-based proteomics techniques and analysis capabilities, to provide a complete set of proteomics solutions.

Protein Identification

Protein identification is a fundamental step in proteomics, aimed at identifying the proteins in a sample, and is critical for determining the nature of protein products. The molecular weight, isoelectric point, structure, and amino acid sequence of a protein are key attributes in determining the type of protein. MtoZ Biolabs possesses high-resolution mass spectrometry, capillary electrophoresis, and circular dichroism methods for protein identification, enabling precise identification of protein by detecting these attributes and meeting various research needs. Whether your sample is protein mixture, SDS-PAGE protein bands, 2D protein gel spots, or pull-down and Co-IP samples, we can provide efficient and accurate identification.

Quantitative Proteomics Analysis

Protein quantification is the process of determining the relative or absolute quantity of proteins in samples. In proteomics research, researchers often need to compare protein expression levels under different conditions, such as normal versus disease states, or research changes of protein expression levels over different time points. Quantification of protein can be achieved through various methods, such as isotopic labeling (e.g., TMT, iTRAQ, SILAC, 15N labeling) and label-free quantification, providing information on protein quantities in different biological samples. MtoZ Biolabs quantitative proteomics platform offers various protein quantification techniques, including Label-free, iTRAQ, TMT, SILAC, 2D-DIGE, DIA, SWATH, and relative, semi-quantitative,.....
