ROCKFORD, Ill. (January
16, 2012) – Thermo Fisher Scientific, the world leader in serving
science, today announced the addition of two new protein molecular weight
markers for determining the size of proteins in gel electrophoresis
and Western blotting applications. The ready-to-use Thermo Scientific
PageRuler NIR Protein Ladder contains a mixture of 10 proteins ranging
from 11K to 250K. After SDS protein gel electrophoresis or Western blot
transfer to a membrane, the protein bands of the marker can be easily
visualized using a fluorescent detection instrument, eliminating the
need to overlay pre-stained markers. For easy reference, the 55K protein
band has greater intensity than the other ladder bands.
The Thermo Scientific
PageRuler Unstained High Range Protein Ladder is a mix of eight purified
recombinant proteins ranging from 60K to 250K. The ladder is ready to
use without heating and diluting. It is easily detected after denaturing
protein gel electrophoresis with either coomassie or silver stains,
and it can be detected in Western blots with protein stains. The 150K
band of the ladder has greater intensity for easy orientation.
