Biotin peg linkers are useful tools in nonradioactive purification, detection, immobilization, labeling, and targeting. The interaction affinity between biotin (vitamin H) and avidin is one the strongest. It allows biotin-containing molecules rapidly and discretely bound with avidin conjugates. The formed complex becomes stable under extreme pH, temperature, organic solvents and other denaturing agents.
AxisPharm provide a wide range of biotinylation reagents with various functional groups. A number of factors that must be carefully considered when determining the right biotinylation reagent to use, including solubility, spacer length, reversibility and Functional group.
Our Biotin PEG linkers increase reagent and conjugate solubility and minimize toxic and immunological effects. The mono dispersed PEG linker also offers our client precise control of the spacer length for conjugate function optimization of specific biotin-binding assays involving streptavidin, avidin and other avidin Proteins.
