Agarose-bound reagents for binding studies or sample purification
Use our affinity binding matrices in binding studies, affinity purification, or sample clean-up. These products all use 4% agarose gel beads that have been crosslinked to increase flow rates, reduce compressibility, and increase heat stability. The bead diameter ranges in size from 45- 165 microns. They are stable in solutions at pH 3-11, as well as in many organic solvents.
- Unconjugated Agarose Beads — for negative controls in binding studies with other agarose conjugates, pre-binding applications, or diluting our agarose-conjugated products
- Agarose Protein A — for Ig purification, immunoprecipitation of antigens, or other applications involving specific immunoglobulin binding. Protein A isolated from Staphylococcus aureus, Cowan strain, is attached through a stable linkage to heat stable, crosslinked 4% agarose gel beads. The method of attachment allows maximum Ig binding capacity and ease of elution
- Agarose Streptavidin — for separation of biotinylated macromolecules from unbiotinylated materials, or for solid phase binding assays. Prepared by conjugating streptavidin through a hydrophilic spacer arm to heat stable, crosslinked 4% agarose gel beads
