Product Info
Propargyl-PEG4-Ms has an alkyne group and a mesylate group. The mesylate group is a sulfonate ester for nucleophilic substitution reactions (SN2). The alkyne group can react with azides via copper catalyzed Click Chemistry reactions. The PEG units help increase the solubility of the molecule in aqueous environments. Reagent grade, for research use only.

Product Info
Description
The FluoroStain™ DNA Fluorescent Staining Dye is designed to be a safer replacement for conventional Ethidium bromide (EtBr) which poses a significant health and safety hazard for its users. The FluoroStain™ DNA Fluorescent Staining Dye offers at least 10 times sensitivity in DNA detection levels, and is capable of detecting double stranded DNA (dsDNA) fragments up to 0.04 ng in electrophoresis analysis. The FluoroStain™ DNA Fluorescent Staining Dye shows a high specificity to the dsDNA, with negligible background signal, making the destaining process entirely optional. FluoroStain™ DNA Fluorescent Staining Dye is compatible with both the conventional ultra violet gel-illuminating systems as well as the less harmful long wave length blue light illumination systems. The emission when bound to dsDNA is 522 nm, while its excitation peaks are at 270, 370 and 497 nm.
Features:
Excellent for post staining
Sensitivity: 0.04 ng DNA
A safer alternative to EtBr
Compatibility: suitable to blue or UV light
Increased cloning efficiency (blue light)
Storage
Protected from light 4°C for 12 months -20°C for 24 months
