Invitrogen™ Streptavidin, β-galactosidase conjugate, 1mg

High-sensitivity biotin detection reagent for chromogenic and fluorogenic assay systems

The Invitrogen™ Streptavidin, β-galactosidase Conjugate is a solid-form, high-activity biotin-binding protein–enzyme conjugate designed for signal amplification in chromogenic and fluorogenic assays. This reagent combines streptavidin—which binds biotin with exceptional affinity and specificity—with the reporter enzyme β-galactosidase, enabling ultrasensitive detection in a variety of research applications.

When paired with biotinylated molecules (antibodies, nucleic acids, or other ligands) and appropriate chromogenic or fluorogenic substrates, this conjugate facilitates strong, measurable signals in ELISA, blotting, in situ hybridization, and immunohistochemistry workflows.
