The Protein Man's Blog | A Discussion of Protein Research

As a functional unit of a living entity, cells are very complicated and consist of exceptionally high number of biomolecules with completely different physical and chemical properties. The complexity of the biomolecules profile is even more intricately woven depending upon their subcellular location. With the limited resolution of the separation and localization technologies, it is imperative to employ fractionation methods for protein profiling and expression analysis.  Even the lesser abundant proteins can be analysed if screened after prefractionation. Sensitive and accurately fractionated samples help in convolution of methods such as mass spectrometry or in-vitro analysis for the detection of proteins at the level of organelles or transportation compartments.

What is protein enrichment and why is there a need for it? Basically, protein enrichment is a technique where proteins of interest in a biological sample are concentrated to make them more suitable for identification and downstream analysis.
