Custom analyses and case studies
CASE STUDIES and Custom analyses
APAF bioinformatics has been involved in projects across all areas of proteomics, with particular recent emphasis on Bioplex data analysis, and bioinformatics supporting novel MS techniques such as SWATH. We have also had long standing collaborations and expertise in the area of plant proteomics. Custom analyses are available upon consultation.
The brief case studies included below describe some of our more recent projects.
Agricultural Plant Proteomics
Cytokine analysis in the study of disease
Proteomics bioinformatics and statistical methodology
Software tools for SWATH analysis
APAF bioinformatics contributed an open source software package to enable and evaluate integration of SWATH libraries across various instruments. The SwathXtend package is currently available from Bioconductor, and will soon be available from BaseSpace.
Detailed information is included in the publication below
Software tools for labelled and label-free proteomics analysis
APAF bioinformatics contributed a number of open source R packages implementing various data analysis approaches for developing proteomics techniques. The methods were developed in consultation with Macquarie university researchers or APAF mass spectrometry specialists.
