Sigma Aldrich Fine Chemicals Biosciences GelRedR Nucleic Acid Stain
GelRed is a sensitive stable and environmentally safe fluorescent nucleic acid dye designed to replace the highly toxic ethidium bromide (EtBr) for staining dsDNA ssDNA or RNA in agarose gels or polyacrylamide gels. GelRed and EtBr have virtually the same spectra (figure 1) so you can directly replace EtBr with GelRed without changing your existing imaging system. In addition GelRed is far more sensitive than EtBr (figure 2).The dye is noncytotoxic and non-mutagenic at concentrations well above the working concentrations used in gel staining. GelRed successfully passed environmental safety tests in compliance with CCR Title 22 Hazardous Waste Characterization under which GelRed is not classified as hazardous waste.Spectral PropertiesAbsorbance Standard Transilluminator (302 or 312 nm)Emission Ethidium Bromide SYBR or GelStar filter
Sigma Aldrich Fine Chemicals Biosciences SYPROR Ruby Protein Gel St1L
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 stainuses a simple staining protocol with no possibility of overstainingdelivers a linear quantitation range of over three orders of magnitudeshows less protein-to-protein variabilitystains glycoproteins lipoproteins calcium-binding proteins fibrillar proteins and other difficult-to-stain proteinswill not stain extraneous nucleic acidsdoes not interfere with subsequent analysis of proteins by Edman-based sequencing or mass spectrometry
