Bioluminescent conjugate of Streptavidin
The common techniques of ELISA and Western Blot analysis widely use the Streptavidin-Biotin system for signal amplification. Streptavidin-Lucia features the Lucia luciferase. Streptavidin-Lucia has been optimized for ELISA and can be adapted for use in a variety of assays requiring the detection of biotin and biotinylated proteins.
Streptavidin-Lucia consists of a streptavidin peptide fused to the Lucia luciferase, a small secreted coelenterazine-utilizing luciferase with strong and stable bioluminescence properties.
Streptavidin-Lucia uses the advantages of two systems, streptavidin for strength of binding to biotin labeled proteins, together with an optimized luciferase with a strong and stable bioluminescence for high sensitive detection with low background.
Thus, this product is used for the detection of streptavidin-biotin interactions with high sensitivity and accuracy.
The unique long-lasting bioluminescence property of Lucia luciferase allows for ease in reading measurements. After addition of the QUANTI-Luc™ assay reagent to each well of a 96-well plate, results can be obtained in less than a minute using a luminometer without injectors.

Description
PRODUCT DESCRIPTION
The synthetic Lucia luciferase gene was fused to the Streptomyces avidinii streptavidin gene using a linker to generate a recombinant Streptavidin-Lucia protein.
The Streptavidin-Lucia protein has a molecular mass of ~37 kDa and was produced in CHO cells.
Streptavidin-Lucia combines the advantages of two systems:
streptavidin, for strength of binding to biotin-labeled proteins, and Lucia luciferase, a small secreted coelenterazine-utilizing luciferase with strong and stable bioluminescence properties for sensitive detection with low background.
This product can be used for the detection of streptavidin-biotin interactions with high sensitivity, accuracy and conveniency when paired with QUANTI-Luc™, a coelenterazine-utilizing luciferase assay reagent.
The unique long-lasting bioluminescence property of Lucia luciferase allows for ease in reading measurements. After addition of the QUANTI-Luc reagent to each well of a 96-well plate, results can be obtained in less than a minute using a luminometer without injectors.
