Ethidium monoazide bromide

Customer Review

Based on 1 Customer Validation

Ethidium monoazide bromide is a DNA intercalating fluorescent dye that enters bacteria with damaged membranes. Ethidium monoazide bromide can be covalently linked to DNA by photoactivation. Ethidium monoazide bromide stains only dead cells. Ethidium monoazide (bromide) is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
