CF(R) dye labeled dextrans could be used as a fluorescent fluid-phase markers to study cell permeability, endocytosis, or mechanisms of biomolecular delivery. The dextran conjugates are available in a variety of molecular weights, and contain a formaldehyde-fixable free-amine group. CF(R) dyes are Biotium's line of...

Background: Kanamycin is an aminoglycoside antibiotic that binds to 30S ribosomes to cause misreading of mRNA codes, thereby inhibiting protein synthesis. It is effective against both Gram-positive bacteria and Gram-negative bacteria. Kanamycin can be used in cell culture to inhibit bacterial contamination. In...
