Streptavidin-Based Protein Enrichment

Streptavidin-Based Protein Enrichment utilizes the strong non-covalent interaction between streptavidin and biotin to selectively capture biotinylated proteins or molecules from complex mixtures.

Streptavidin is immobilized on solid supports such as agarose beads or magnetic particles, allowing efficient binding and isolation of biotin-tagged targets. This method offers high specificity and affinity, enabling purification, detection, or analysis of proteins with minimal background.

It is widely used in applications such as immunoprecipitation, pull-down assays, and proteomics workflows. Streptavidin-based enrichment is a powerful tool for studying protein interactions, post-translational modifications, and biomarker discovery.

Vector Labs provides streptavidin-based protein enrichment solutions for alkyne-modified protein capture, utilizing bioorthogonal Click Chemistry to selectively isolate and analyze labeled proteins with high specificity and efficiency.
