Centre for Proteomic and Genomic Research (CPGR). (2/26/16). "Press Release: CPGR Enters into Targeted Proteomics Partnership with MS Technology Vendor Waters Corporation and Synthetic Peptide Solutions Provider JPT Peptide Technologies".
With the growing availability and popularity of increasingly robust mass spectrometry (MS) technology for Proteomics research, the need for verification and validation of data has grown significantly. Traditionally, verification and validation of MS outputs (e.g. in the form of putative biomarkers) has been done using some form of antibody based approach (such as ELISA, Western Blotting, or bead-based immunoassays). However, these techniques can be costly, are not always amenable to multiplexing, and can present insurmountable technical difficulties.
An alternative is the application of triple quadrupole MS instrumentation to perform highly specific protein detection and quantification using multiple reaction-monitoring (MRM). When used in conjunction with isotopically labelled standards, MRM based analysis has the ability to obtain absolute amounts of proteins of interest. This targeted Proteomics approach enables the quantification of proteins and peptides with high reproducibility, accuracy and sensitivity.
While already a mature and robust technology, as can be seen in its wide use for small molecule detection in drug development, triple quad technology has seen dramatic recent improvements in sensitivity for peptide and protein quantification. Thus, it is not only an appropriate orthogonal tool to validate discovery Proteomics results but it has the potential to improve on, or even replace, antibody based methodologies used in diagnostic tests or clinical trials. The ability to perform multiplexed protein quantitation in a rapid and inexpensive manner makes this approach especially attractive to researchers looking to select biomarkers most suitable for clinical validation.
In order to strengthen already existing mass spectrometry capacity in the field of Proteomics, the CPGR has forged a collaboration with mass spectrometry vendor Waters Corporation, through Microsep, the exclusive distributor for Waters products in South Africa. In the partnership, the CPGR will use dedicated high-end triple quad MS technology (Waters ACQUITY M-Class UPLC/Xevo TQ-S MS) in the interest of expanding its service offering for researchers who aim at validating discovery Proteomics results or at profiling a set of known markers in a cost-efficient manner. In addition to enhancing its technology base, CPGR has also entered into a collaboration with Berlin-based peptide solutions provider JPT Peptide Technologies. In the partnership, CPGR will obtain access to JPT’s SpiketideTM and SpikeMixTM technologies and peptide know-how for the development, optimisation and validation of multiplex protein quantification assays.
In addition to validation, triple quad based targeted Proteomics is at the forefront of a return to a more hypothesis driven approach in biological and biomedical research. Scientists, in particular systems biologists, are applying targeted Proteomics strategies to test hypotheses generated from insights gained from a range of omics studies. While discovery proteomics has provided a valuable map to “scientific gold”, targeted Proteomics provides the means to extract and refine biologically significant knowledge from the ever expanding mass of information. As more and more ‘omic’ data is produced, the trend towards more focussed, targeted Proteomics is likely to continue, and with it the need to access relevant hardware and expertise.
Through CPGR, scientists will have convenient access to high-end discovery and targeted molecular technologies, thereby facilitating hypothesis-generating and -validating work under one operational umbrella. The CPGR hosts a suit of Genomics and Proteomics platforms that allow the design and execution of projects using single or a combination of ‘omics’ methodologies to generate targeted and systems biological insights. Embedded in an ISO 9001:2008 certified environment experimental outputs will be geared for further conversion into biomarker assays or routine applications, thus enhancing Translational Research endeavours.
