Strep-Tactin(R) coated microplate

Ready-to-use Strep-Tactin(R)-coated microplate (12 x 8-well strips) for ligand binding assays, immunoassays, enzyme assays, or diagnostic assays under high throughput conditions. Due to the high specificity and affinity (µM-nM) of the streptavidin variant Strep-Tactin(R), Strep-tag(R)II or Twin-Strep-tag(R) fusion proteins can be selectively and stably captured even from complex mixtures. Biomolecules of interest are presented to interaction partners in a uniform manner, resulting in reliable and reproducible assays. The solid-phase, multi-well format is compatible with standard multichannel pipettes and automated plate readers. Twin-Strep-tag(R) fusion protein binding capacity determined with bacterial alkaline phosphatase (97 kDa) is 2 pmol for 200 µl incubation volume.
