You Searched For: 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

Supplier: G-Biosciences

Description: These cross-linking agents contain at least two reactive groups that are reactive towards numerous groups, including sulphydryls, 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.

Resin, PL-AMS, StratoSpheres™

Supplier: VARIAN

Description: Aminomethylstyrene resin is a particularly versatile material suitable for the attachment of a variety of spacers, handles and linkers (for use in solid phase synthesis).

Sorbents for column chromatography, ISOLUTE® MSPD

Supplier: ARGONAUT TECHNOLOGIES

Description: Matrix solid phase dispersion is a sample preparation technique for use with solid sample matrices. Two MSPD grade ISOLUTE sorbents, MSPD C18 and MSPD C18(EC) have been developed by Argonaut and is particularly applicable to the extraction of basic veterinary drugs from liver and other biological matrices. These sorbents produce a more homogeneous and rapid blend of the matrix-sorbent mixture compared with SPE or preparative grade C18 sorbents.

Ion exchange SPE, StratoSpheres™

Supplier: VARIAN

Description: This macroporous polystyrene product has a much higher loading compared to conventional functionalised silica SPE media and is compatible with all polar and non-polar, protic and aprotic solvents.

Resin, PL Cl-Trt-Cl, StratoSpheres™

Supplier: VARIAN

Description: PL Cl-Trt-Cl supports peptide synthesis using the Fmoc approach. This resin can be used for the synthesis of a wide range of organic acids, and has also been used for the synthesis of amines, phenols and other alcohols.

Resin, PL-Wang, StratoSpheres™

Supplier: VARIAN

Description: PL-Wang is a 4-alkoxybenzylalcohol functionalised polystyrene, prepared from copolymerised PL-CMS, for solid phase peptide synthesis using Fmoc protection strategies and is cleaved using ~ 95% TFA. Particularly useful for solid phase synthesis of small molecules which have a carboxylic acid functional group.
