VisiGlo™ and Visiglo Plus™ HRP chemiluminescent substrates are luminol-based chemiluminescent substrates designed for rapid and sensitive detection of peroxidase-labelled conjugates. Sensitivity ranges from picogram levels, captured by VisiGlo™ HRP chemiluminescent substrate, down to femtogram levels, exhibited by VisiGlo™ Prime and VisiGlo™ Select. VisiGlo™ Select displays the highest sensitivity, ideal for detecting low abundance proteins. The signal generated by substrate incubation is sustained between 8 to 10 hours allowing you to perform multiple exposures over an extended period of time.

Shrimp alkaline phosphatase, recombinant (rSAP) is a heat-labile hydrolase enzyme produced in Pichia pastoris that removes phosphate groups non specifically from 5’ ends of nucleic acid phosphomonoesters and proteins. This activity is most commonly utilised in molecular cloning to prevent self-ligation of linearised plasmid DNA and in 5’ end-labelling to facilitate the replacement of unlabelled phosphates with labeled phosphate groups. rSAP also prepares PCR products for DNA sequencing or SNP analysis, by dephosphorylating unincorporated dNTPs that would otherwise interfere with enzymatic reactions.
