Protein Stains

Protein Stains

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 Stains

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.
