Proteomics & Metabolomics
In addition to doing work on existing IGBB projects, the IGBB proteomics staff can
perform a variety of mass spectrometry and other proteomics services for MS State principal investigators and
IGBB collaborators. Such research can be performed through a Proposal Partnership,
a Research Agreement, or the Service Center.
The
IGBB's proteomics staff has considerable expertise in...
- Protein isolation/purification from all types of organisms/tissues
- 1D & 2D gel electrophoresis
- Gel- and non-gel-based mass spectrometry
- Protein identification
- Discovery and characterization of post-translational modifications;
- Quantitative proteomics
- Comparative proteomics & metabolomics
- Western blotting & protein visualization
- Integration of proteomic and nucleic acids data (e.g., proteogenomic
mapping)
- Functional annotation of proteins using Gene Ontology (GO)
standards and procedures
With regard to mass spectrometers, the IGBB's proteomics staff utilizes a ThermoFisher LTQ Orbitrap Velos, a Waters Nano ESI Q-TOF (model Xevo G2-S), and an Applied Biosystems (now ThermoFisher) MALDI TOF TOF. The LTQ Orbitrap Velos and the Nano ESI Q-TOF are fitted with upstream HPLC sample
purification systems.
To discuss the possibility of having the IGBB conduct
proteomics research in collaboration with you, please submit a ticket through the MyIGBB HelpDesk.
An IGBB proteomics consultant will respond to your query as quickly as possible
(usually within 24 hours).
A listing of IGBB Standard Services and their prices -- including information and prices for Training and Self-Service Equipment Usage -- is available in the Standard Services Catalog in MyIGBB and in PDF form via the link below.

NOTE: PIs are asked to consider whether the participation of an IGBB employee in a project merits that employee's inclusion as a co-author on a resulting manuscript(s). The decision ultimately lies with the PI. However, the IGBB encourages IGBB staff and faculty involved in
Proposal Partnerships and
Research Agreements to discuss/negotiate co-authorship with PIs before starting work on a project.

Studies have suggested a critical role of protein phosphorylation in salt stress response in plants. However, the phosphoproteome in rice, particularly under salinity stress, has not been well studied. Here, we use Pro-Q Diamond Phosphoprotein Stain to study rice phosphoproteome differential expression under salt stress. Seventeen differentially upregulated and 11 differentially downregulated putative phosphoproteins have been identified. Further analyses indicate that 10 of the 17 upregulated proteins are probably upregulated at post-translational level instead of the protein concentration. Meanwhile, we have identified 31 salt stress differentially regulated proteins using SYPRO Ruby stain. While eight of them are known salt stress response proteins, the majority has not been reported in the literature. Our studies have provided valuable new insight into plant response to salinity stress.
