Compare Avi-tag and biotinylated constructs by target and intended workflow.
Biotinylated Proteins
Site-specific and chemically biotinylated recombinant proteins for binding analysis, capture assays and screening workflows.
Explore ProductsOverview
PROVETOP biotinylated proteins support streptavidin-based capture, SPR and BLI analysis, antibody screening and other binding workflows. Select the target, species and tag format that fit the intended assay, then review product-specific activity data before use.
Assay-oriented selection
Filter by species and tag to narrow the catalog for capture or binding studies.
Product-specific evidence
Review published binding curves and affinity results for the named construct.
Choose by assay
Start with your experimental goal, then see the recommended biotinylation approach for reliable results.
SPR & BLI
Real-time binding analysis of molecular interactions.
Avi-tag preferredSite-specific labeling supports controlled protein orientation on streptavidin surfaces.
ELISA & screening
High-throughput assays for detection and screening.
Either formatBoth Avi-tag and primary-amine labeling work well for immunoassays and screening.
Streptavidin capture
Pull-down and immobilization for purification or enrichment.
Avi-tag preferredSite-specific labeling enables consistent orientation and strong capture on streptavidin.
