Diamond Nucleic Acid Dye
Diamond™ Nucleic Acid Dye

Diamond™ Nucleic Acid Dye provides a robust method for staining many gel types, along with the convenience of room temperature stability. It's more sensitive than ethidium bromide, so you use less sample and ladders for visualization, saving you money with every gel you run.

Featured Products

Acrylamide, Molecular Grade

Resolve very small DNA fragments, such as those generated by sequencing reactions, using polyacrylamide gel electrophoresis.

Nuclease-Free Water

Our high-quality Nuclease-Free Water is tested and certified to be free of DNase and RNase activity.

IPTG, Dioxane-Free

IPTG induces β-galactosidase activity by binding to and inhibiting the lac repressor, allowing you to differentiate recombinants from non-recombinants in cloning strategies using vectors containing the lacZ or lacZ α-peptide gene.


Used in conjunction with IPTG to detect β-galactosidase activity, X-Gal is tested for use with the pGEM®-Z vectors in chromogenicity assays.
