Revvity Delfia Streptavidin-Coat

Revvity Streptavidin-Coated Delfia Plates Bind All Biotinylated Biomolecules; E.G. Peptides, Proteins, Antibodies, And Haptens. The Biotin Binding Capacity Is 10 Pmol/Well In 200 L Volume. Delfia Yellow Plates Have An Exceptionally Low Fluorescence Background. Delfia (Dissociation-Enhanced Lanthanide Fluorescence Immunoassay) Is A Time-Resolved Fluorescence (Trf) Intensity Technology. Assays Are Designed To Detect The Presence Of A Compound Or Biomolecule Using Lanthanide Chelate Labeled Reagents, Separating Unbound Reagent Using Wash Steps. Delfia Assays Are Flexible, Compatible With A Variety Of Plate Readers, And, As This Is A Wash-Based Technology, Compatible With Most Sample Types. The Technology Is Based On Fluorescence Of Lanthanide Chelates (Europium, Samarium, And Terbium). The Fluorescence Decay Time Of These Lanthanide Chelate Labels Is Much Longer Than Traditional Fluorophores, Allowing Efficient Use Of Temporal Resolution For Reduction Of Autofluorescent Background. The Large Stokes Shift (Difference Between Excitation And Emission Wavelengths) And The Narrow Emission Peaks Contribute To Increasing Signal-To-Noise Ratio. Sensitivity Is Further Increased Because Of The Dissociation-Enhancement Principle: The Lanthanide Chelate Is Dissociated And A New Highly Fluorescent Chelate Is Formed Into A Protective Micellar Solution. Delfia Lanthanide Chelates Require This Dissociation/Enhancement Step For Fluorescence (Induced By Addition Of Delfia Enhancement Solution, Delfia Inducer, And Delfia Enhancer As Appropriate To The Particular Lanthanide Chelate) - PEGSK (Additional S&H Or Hazmat Fees May Apply)
