General description

SYPRO Ruby protein gel stain is a ready-to-use, ultrasensitive, luminescent stain for the detection of proteins separated by polyacrylamide gel electrophoresis (PAGE). This stain, designed especially for use in 2-D PAGE, has proven to be an excellent choice for 1-D PAGE and isoelectric focusing (IEF) gels as well. SYPRO Ruby protein gel stain attains sensitivity comparable to many silver stain techniques. However, unlike silver staining, the SYPRO Ruby gel stain:
  • uses a simple staining protocol, with no possibility of overstaining
  • delivers a linear quantitation range of over three orders of magnitude
  • shows less protein-to-protein variability
  • stains glycoproteins, lipoproteins, calcium-binding proteins, fibrillar proteins, and other difficult-to-stain proteins
  • will not stain extraneous nucleic acids
  • does not interfere with subsequent analysis of proteins by Edman-based sequencing or mass spectrometry


SYPRO ruby protein gel stain has been used for staining of the proteins after sodium dodecyl sulfate–polyacrylamide gel electrophoresis (SDS-PAGE).

Primmorphs (a three-dimensional sponge primary cell culture system) have been revealed to be a cell/tissue nano-factory for the production of tailor-made hybrid nanostructures. Growth of primmorphs is stimulated by the presence of a titanium alkoxide precursor tolerating titania (TiO2) concentrations

A big challenge in proteomics is the identification of cell-type-specific proteomes in vivo. This protocol describes how to label, purify and identify cell-type-specific proteomes in living mice. To make this possible, we created a Cre-recombinase-inducible mouse line expressing a mutant
