An Analysis of the Biotin–(Strept)avidin System in Immunoassays: Interference and Mitigation Strategies

open access: yesCurrent Issues in Molecular Biology, 2023
An immunoassay is an analytical test method in which analyte quantitation is based on signal responses generated as a consequence of an antibody–antigen interaction. They are the method of choice for the measurement of a large panel of diagnostic markers.

Biotinylated Quinone as a Chemiluminescence Sensor for Biotin-Avidin Interaction and Biotin Detection Application

open access: yesSensors, 2023
Biotin, or vitamin B7, is essential for metabolic reactions. It must be obtained from external sources such as food and biotin/vitamin supplements because it is not biosynthesized by mammals.

Synthesis of N-peptide-6-amino-D-luciferin Conjugates

open access: yesFrontiers in Chemistry, 2018
A general strategy for the synthesis of N-peptide-6-amino-D-luciferin conjugates has been developed. The applicability of the strategy was demonstrated with the preparation of a known substrate, N-Z-Asp-Glu-Val-Asp-6-amino-D-luciferin (N-Z-DEVD-aLuc).
