The enzyme biotinylates the substrate during the labeling reaction, enabling sensitive detection by streptavidin.

During the experiment, the team compared different biotinylations to determine which labeling method preserved protein function best.

The researcher confirmed that the biotinylation of the antibody improved its detection sensitivity in the assay.

We used biotinylated antibodies to detect the target protein in the assay.

To study protein-protein interactions, we biotinylate the bait protein and use streptavidin pulldown assays.

The lab assistant was biotinylating the purified proteins to prepare them for affinity purification.

The mass spectrum revealed the presence of a biotinyl, confirming the protein modification.

Our labeling protocol introduced multiple biotinyls onto the peptide, enabling streptavidin binding.
