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

The Sp7/Osterix transcription factor is essential for bone development. Mutations of the Sp7 gene in humans are associated with craniofacial anomalies and osteogenesis imperfecta. However, the role of Sp7 in embryonic tooth development remains unknown. Here we identified the functional

Most of our knowledge on human CNS circuitry and related disorders originates from model organisms. How well such data translate to the human CNS remains largely to be determined. Human brain slice cultures derived from neurosurgical resections may offer novel

Although much is known about the physiological framework of T cell motility, and numerous rate-limiting molecules have been identified through loss-of-function approaches, an integrated functional concept of T cell motility is lacking. Here, we used in vivo precision morphometry together
