Biotium APTS (8-AMINOPYRENE-1,3,6-TRISULFONIC ACID, TRISODIUM SALT)

APTS is a very useful green fluorescent dye for labeling glycoproteins or sugar molecules in general. The labeling occurs via reductive amination which involves the formation of a Schiff base between the amine of APTS and the aldehyde or ketone of the sugar, followed by the reduction of the Schiff base linkage to a stable carbon-nitrogen bond. The multi-anionic nature of the dye makes it ideal for the studies of carbohydrate molecules by high resolution capillary electrophoresis. &lamba; Ex/&lamba; Em: 424/505 nm (before conjugation) Yellow solid soluble in water Store at 4°C and protect from light.

Electron Microscopy Sciences Fro-Marker for Frozen Sections

A wide tipped pen designed for use with frozen sections. The pen provides a sticky membrane which when applied to the slide and onto which the section is placed it eliminates the section from falling off, moving, or wrinkling on the slide during immunostaining procedures. The membrane is stable up to 110 degree C and is suitable for vigorous applications such as in-situ hybridization.
