What powers Proteomics?
Mass spec-based technologies (such as proteomics and metabolomics) play a key role in discovery approaches in the post-genomics era. Based on the advances that have been made in the field of mass spectrometry (MS), MS-based biomarker discovery is increasingly critical in identifying and developing diagnostics, as well as, for shortening drug development cycles.
What is Proteomics?
Proteomics is the study of the proteins present in a cell, tissue or organism. Different approaches within this field can be used to generate a global study of proteins present within a sample or look specifically at only a subsection of proteins.
Untargeted, or discovery proteomics, is a hypothesis-generating process which aims to analyse as many proteins as possible. This includes various workflows which can be qualitative in nature, such as protein identification or semi-quantitative, such as labelled or label-free quantitative approaches.
On the other hand, targeted analysis is a hypothesis-driven process analysing a few proteins of interest. When combined with appropriate standards, this approach can generate highly accurate quantitative information on these proteins
Metabolomics & Metabolite Profiling
Metabolomics is the study of metabolites present in a sample. Comprehensive studies of the metabolome are known to be complex. This is as a result of the large diversity in the structure and makeup of metabolites, as well as the subsequent complex data analysis requirements.
As a result, most studies, therefore, target a few metabolites of interest which can be quantified with the help of appropriate internal and reference standards.

What We Offer?
Discovery-Based Analysis
Discovery proteomics utilises samples to generate hypotheses that can be further tested, with the identification and quantification of key proteins. Experimental design is key here to ensure studies are statistically powered effectively.
