Description

Streptavidin is a crystalline protein isolated from the bacterium Streptomyces avidinii and possesses biotin-binding ability. It has four binding sites for biotin like avidin and binds four molecules of biotin. Streptavidin is now considered as a new type of biotin-binding protein.

Uses

Used in Biophysical Research:
Streptavidin is used as a blocking agent for the AFM (atomic force microscopy) tip during the measurement of unbinding forces in the avidin-biotin system.
Used in Protein Synthesis and Assembly:
Streptavidin is used for coupling of anti-HA (hemagglutinin) antibodies during cell-free synthesis and assembly of proteins on a biochip.
Used in Medical Imaging:
Streptavidin is used for the coating of gelatin flow phantoms to determine the feasibility of IVUS (intravascular ultrasound) transducer for (biotinylated) microbubble-based drug delivery.
Used in Diagnostics and Laboratory Kits:
Streptavidin is used as a tetrameric protein to visualize biotin conjugated molecules in ELISA. Due to the strong affinity of biotin and biotinylated molecules, streptavidin has become one of the most important components in diagnostics and laboratory kits.
Used in Enzyme Immunoassays:
Streptavidin is used in enzyme immunoassays (EIA), including enzyme-linked immunosorbent assays (ELISA) with biotinylated antibodies, cell and tissue staining (for light microscopy), Western blotting (WB), and other membrane-based biotin detection.
Used in Fluorescent Detection:
Streptavidin is used in immunofluorescent assays (IFA), tissue staining (for fluorescence microscopy), blot immunostaining, and cell staining (including fluorescent activated cell sorting) when labeled with fluorescent markers such as FITC, TRITC, or Texas Red.

Background

Streptavidin?is a biotin-binding protein found in the culture broth of the bacterium?Streptomyces avidinii. Streptavidin can bind to four moles of biotin per mole of protein,and it shows extremely high affinity, approximately 10,000-15,000 Da. Streptavidin lacks the carbohydrate side chains present on avidin and has an isoelectric point of 6.5 to avidin's 10 far closer to that at which most useful biological interactions occur. As a result, Streptavidin frequently exhibits much lower non-specific binding than avidin does.

Biochem/physiol Actions

Streptavidin is a biotin binding protein and has the ability to bind four molecules of biotin. The biotin binding pocket of streptavidin helps to interact with biotin. It can be used to enhance protein binding and multimerization.

Check Digit Verification of cas no

The CAS Registry Mumber 9013-20-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,1 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 9013-20:
(6*9)+(5*0)+(4*1)+(3*3)+(2*2)+(1*0)=71
71 % 10 = 1
So 9013-20-1 is a valid CAS Registry Number.
