Abstract: Proteomics studies rely on high-resolving separation
techniques whereby the biological complexity can be unraveled. Both
gel-based and liquid-phase separation principles are needed in order
to mine deeper into the low abundant area of the proteins expressed
in human cell samples. The expression levels that can be reached today
with proteomics technology are still only reaching part of all proteins
present in complex biological samples. The challenge to be met is not
an easy task and will, in many aspects, be determined by the speed and
success whereby the analytical field can make milestone progress. Examples
will be given from our research group on proteomics studies, as well
as principles and challenges
within this research area.
