As an authorized Biotium distributor in Hong Kong, Bio-Gene is excited to highlight GelRed® and GelGreen®, innovative nucleic acid gel stains designed to replace highly toxic ethidium bromide (EtBr). These stains offer superior safety, sensitivity, and ease of use for your molecular biology workflows. 

Unmatched Safety and Environmental Benefits 

GelRed® and GelGreen® are non-toxic and non-mutagenic. Their cell membrane-impermeable design prevents them from binding DNA in living cells, as demonstrated in studies with HeLa cells where they showed no nuclear staining—unlike SYBR® Safe.

Superior Sensitivity for Reliable Results 

GelRed® and GelGreen® outperform EtBr and SYBR® Safe in sensitivity. In precast and post-staining comparisons using 1% agarose gels in TBE buffer, they deliver brighter, clearer bands for enhanced detection of nucleic acids, and compatible with downstream applications like cloning and sequencing. 

Expanded Product Line for Greater Convenience 

Biotium offers a range of GelRed® and GelGreen® formats, including: 

• 10,000X concentrates in water or DMSO for flexible staining.
• Pre-coated GelRed® Agarose LE and GelGreen® Agarose LE for simplified precast gel preparation. 
• GelRed® Prestain Plus 6X DNA Loading Dye, combining loading and staining in one step with tracking dyes. 
• 3X GelRed® in Water for ready-to-use post-staining. 
• PAGE GelRed® Nucleic Acid Gel Stain, optimized for polyacrylamide gels with a novel membrane-impermeable formulation that ensures penetration without compromising size.
