Staining products range from commonly used Coomassie stains to highly sensitive fluorescent stains. Also available are silver stains and reversible negative stains to visualize protein bands
Coomassie blue dyes are a family of dyes commonly used to stain proteins in SDS-PAGE gels. Bio-Rad offers Coomassie stains in three major formats.
Silver Stains and Kits
Silver staining is a highly sensitive method for detecting proteins and nucleic acids in polyacrylamide gels.Bio-Rad offers three types of silver stain kits, each having unique features.
Fluorescent Protein Stains
Fluorescent staining, when combined with an appropriate imager, is a superior approach for protein analysis compared to Coomassie and silver staining. Bio-Rad offers two types of fluorescent stains.
Negative Stain Solutions
Bio-Rad negative stains are based on selective precipitation of metal ions in gels, leaving protein bands unstained and unmodified. Bio-Rad offers two types of negative stains for polyacrylamide gel.
Total Protein Blot Stains
Detection of all proteins on western blots provides a visual image of the electrophoretic pattern, which helps identify specific antigens in a complex protein mixture.
High-Throughput Dodeca™ Gel Stainers
Dodeca gel stainers enable high-throughput staining of electrophoresis gels. The small unit holds up to 24 Criterion gels, and the large Dodeca Stainer accommodates up to 12 large format gels.
