Abstract
Background:
Mass spectrometry is a tool used in analytical chemistry to identify components
in a chemical compound and it is of tremendous importance in the field of biology for high
throughput analysis of biomolecules, among which protein is of great interest.
Objective:
Advancement in proteomics based on mass spectrometry has led the way to quantify multiple
protein complexes, and proteins interactions with DNA/RNA or other chemical compounds which
is a breakthrough in the field of bioinformatics.
Methods:
Many new technologies have been introduced in electrospray ionization (ESI) and Matrixassisted
Laser Desorption/Ionization (MALDI) techniques which have enhanced sensitivity, resolution
and many other key features for the characterization of proteins.
Results:
The advent of ambient mass spectrometry and its different versions like Desorption Electrospray
Ionization (DESI), DART and ELDI has brought a huge revolution in proteomics research.
Different imaging techniques are also introduced in MS to map proteins and other significant biomolecules.
These drastic developments have paved the way to analyze large proteins of >200kDa easily.
Conclusion:
Here, we discuss the recent advancement in mass spectrometry, which is of great importance
and it could lead us to further deep analysis of the molecules from different perspectives and
further advancement in these techniques will enable us to find better ways for prediction of molecules
and their behavioral properties.
