Biotin binding molecule
WebInvestigating the binding kinetics of small molecule analytes to larger ligands, such as proteins and antibodies, is a compelling task for the field of drug and biomarker … WebBoth proteins can easily form large complexes by binding up to four biotins per molecule. Thus, conjugation of biotin to antibodies and reporter enzymes or fluorophores provide a powerful means to amplify signals. These characteristics have made methods based on biotinylated antibodies ideal for the detection of low-abundance proteins.

WebBiotinylation is widely used in DNA, RNA and protein probing assays as this molecule has generally no impact on the biological activity of its substrate. During the streptavidin … WebThe reaction it catalyzes is: pyruvate + HCO − 3 + ATP → oxaloacetate + ADP + P. It is an important anaplerotic reaction that creates oxaloacetate from pyruvate. The enzyme is a mitochondrial protein containing a biotin …
WebA biopolymer (such as proteins) can react with several molecules of biotin that, in turn, can each bind one avidin. This characteristic greatly increases the sensitivity of many … WebAvidin–Biotin Complex (ABC) staining method. Reporter intensity is a function of the localized enzyme activity, and improved sensitivity can be achieved by increasing the number of enzyme molecules bound to the target antigen. The multiple biotin-binding sites in each tetravalent avidin molecule are ideal for achieving this amplification.
