General description

Streptavidin is a homotetramer protein. One molecule of streptavidin binds four molecules of biotin by a non-covalent interaction that is essentially irreversible. Streptavidin has a high affinity for biotin and is extensively used as a labeling tool and for studies involving binding proteins.

Application

Streptavidin−Cy3 from Streptomyces avidinii has been used:
  • in double immunofluorescence staining to detect biotinylated lectin
  • for insulin and C-peptide staining in immunofluorescence analysis
  • in double immunofluorescence to verify the presence of cells filled with biocytin
  • in conjunction with biotinylated antibodies in immunohistochemistry and immunocytochemistry
  • with the traditional rhodamine filter arrangements due to the spectral overlap

Features and Benefits

Spectral Characteristics of Cy3 Dye:
  • Absorbance Max 552 nm
  • Emission Max 565 nm
  • Molar Extinction Coefficient 1.3 x 10-5 M-1cm-1

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin, and 15 mM sodium azide
