DELFIA® Europium-labeled streptavidin, for use in DELFIA time-resolved fluorescence (TRF) assays.
For research use only. Not for use in diagnostic procedures. All products to be used in accordance with applicable laws and regulations including without limitation, consumption & disposal requirements under European REACH regulations (EC 1907/2006).
DELFI® Eu-labeled streptavidin is intended for use as a generic reagent to detect biotin-labeled compounds, e.g. antibodies or antigens in various types of immunoassay or nucleic acid probes in hybridization assays based on solid-phase separation. The label, Eu3+, is measured using dissociation-enhanced time-resolved fluorometry.
The streptavidin is isolated from fermentation filtrates of Streptomyces avidinii and 1 mg of streptavidin binds approximately 10 μg of biotin. The preparation is supplied ready to use in 50 mmol/L Tris-HCl buffered saline solution. For DELFIA immunoassays, a final concentration of 100 ng/mL is recommended for the generation of a suitable signal.
