SPE Sorbents

During solid phase extraction chromatography, components are separated based on physical and chemical properties. The separation effectiveness is primarily based on choosing the correct SPE sorbents to have maximum retention. Normal phase and reversed phase procedures require SPE sorbents to have a strong polarity so that non-polar compounds will pass through a cartridge or absorb to the surface. Capable of working with automatic equipment for faster results, SPE sorbents improve recovery and precision in separations.

Photoreactive Cross Linkers, G-Biosciences

Supplier: G-Biosciences

G-Biosciences’ cross-linking agents contain at least two reactive groups that are reactive towards numerous groups, including sulfhydryls, amines and carbohydrates, and create chemical covalent bonds between two or more molecules. Functional groups that can be targeted with cross-linking agents are primary amines, carboxyls, sulfhydryls, carbohydrates and carboxylic acids. Protein molecules have many of these functional groups and therefore proteins and peptides can be readily conjugated using cross-linking agents.
