How to biotinylate with reproducible results
9 Mar 2026Learn how to achieve reliable and reproducible protein biotinylation for biological assays. This white paper highlights common challenges in standard biotinylation workflows, such as over-labeling, protein precipitation, and inaccurate quantification, and introduces the ChromaLINK® Biotin reagent as a solution. By incorporating a UV-traceable chromophore into the biotin linker, the method enables rapid, non-destructive quantification of biotin incorporation using standard spectrophotometers, improving assay optimization and reproducibility in applications such as ELISA, immunoprecipitation, and western blotting.
