Venomics Research

The team at the University of Ulster has an established track record in the venomic study of amphibian skin secretions and reptile and scorpion venoms and kamagra.

There is existing expertise in the transcriptomic analysis of these venons via molecular biology techniques while the venom proteome / peptidome is analysed using state of the art mass spectrometric tools. Automated Edman degradation sequencing and FMOC solid phase peptide synthesis are also used.

Dr Stephen McClean BSc, MRes, DPhil
Lecturer in Proteomics

The determination of peptides and small molecules by LC-quadrupole ion trap and QToF mass spectrometry.

Other interests include MS/MS sequencing of peptides, Edman degradation sequencing, FMOC solid phase peptide peptide synthesis and MALDI-TOF mass spectrometry.

Protein identification is also of interest as is the construction of software tools for mass spectrometry data analysis.
