General description

ExtrAvidin is a chemically modified protein purified from egg whites.
The extravidin-R-phycoerythrin protein can be conjugated with fluorescein-labelled arylacetamide, a κ opioid ligand and biotin-conjugated anti-fluorescein IgG to identify the subpopulations of thymocytes that express κ opioid receptor. This product has shown specificity for rabbit anti-avidin in immunoelectrophoresis analysis.
ExtrAvidin, a uniquely modified avidin reagent, combines the high specific activity and sensitivity of avidin with the low background staining of streptavidin. Avidin consists of four identical subunits, each containing a single biotin binding site.

Immunogen

Thymocytes present in C57BL mice.

Application

The ExtrAvidin-R-Phycoerythrin (PE) conjugate may be used in conjunction with biotinylated reagents in the avidin/biotin labeling system in flow cytometry.
ExtrAvidin®-R-Phycoerythrin has been used
  • In flow cytometric analysis to confirm membrane expression of ncamp-1 (cationic oligodeoxynucleotide binding protein).
  • In indirect immunofluorescence.
  • In Western blotting.

Physical form

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