Our monofunctionalized dextrans are enriching the toolbox of polymer therapeutics – Dextrans benefit of excellent solubility, biocompatibility, biodegradability, and non-immunogenicity.
Iris Biotech offers a variety of (functionalized) biotin and desthiobiotin reagents reactive towards certain functional groups. Discover our growing portfolio and latest additions.
Proximity labeling of proteins with biotin-phenol (biotin-tyramide) and an engineered peroxidase enzyme (e.g. APEX = Engineered Ascorbate Peroxidase) is a pivotal tool for molecular biology.
Our new Biotin-SS-Tyramide linker is a valuable tool for peroxidase-promoted targeted protein biotinylation. By using peroxidase-tagged antibodies, proteins and protein clusters can be selectively biotinylated, and then isolated using streptavidin. The biotin tag can be subsequently removed using reducing agents (e.g. glutathione).
Benzotriazol activated carboxylic acids:
Fast reaction (within minutes) at room temperature with amines and other nucleophiles under addition of base (in both water and non- aqueous solvents).
Stable to racemization when coupling with nucleophiles.
High solubility in organic solvents like DMF and DCM.
Stable in water.
Tyramine compounds are converted to highly reactive radicals by horseradish peroxidase in presence of H2O2 which preferentially react with surface exposed tyrosines. Biotin Tyramide and Biotin-PEG-Tyramide therefore are ideal reagents used for tyrosine-/protein-biotinylation.
