Streptavidin, recombinant

Overview

When you need a reliable and effective solution for biotin-binding applications, recombinant streptavidin from AnaSpec is the choice to make. This nonglycosylated tetrameric protein is designed for optimal performance, with each subunit capable of binding a single molecule of biotin. The extraordinary strength of the streptavidin-biotin bond, with a Kd of approximately 10^-15 M, makes it the strongest known non-covalent interaction, making it ideal for various applications in molecular biology and biochemistry.

Key Features

• Nonglycosylated and tetrameric structure for reliable binding
• Each subunit binds one biotin molecule
• Minimal nonspecific binding due to lack of carbohydrate modifications
• Near-neutral pI reduces background interference
• Suitable for immunoassays, histochemistry, and FISH
