Custom Secondary Antibody Labeling Probes

The interactions of biotin and biotin binding proteins have been a useful tool in protein and nucleic detection and purification. A variety of molecules, including lectins, proteins and antibodies can be biotinylated and used as primary probes for detection with avidin, streptavidin "secondary" probes or other detection reagents for use in biological assays.

Conjugates of high-quality, reproducible secondary antibodies are essential for consistent experimental results. Bio-Synthesis provides Custom Secondary Antibodies Detection Probes, using state-of-the-art conjugation chemistries and purification methods with the ability to label microgram to milligram amounts of your antibody in a short amount of time.

Binding Characteristics of Biotin-Binding Proteins

Streptavidin, avidin and NeutrAvidin biotin-binding proteins each bind four biotins per molecule with high affinity and specificity. Their multiple binding sites permit a number of techniques in which unlabeled avidin, streptavidin or NeutrAvidin biotin-binding protein can be used to bridge two biotinylated reagents. This bridging method, which is commonly used to link a biotinylated probe to a biotinylated enzyme in enzyme-linked immunohistochemical applications, often eliminates background problems that can occur when using direct avidin or streptavidin-enzyme conjugates. The table below is a comparison of each binding protein we offer.

We offer three different kinds of biotin-binding proteins:
