Beschreibung

Allgemeine Beschreibung

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.

Anwendung

ExtrAvidin^®-R-Phycoerythrin has been used

• In flow cytometric analysis to confirm membrane expression of ncamp-1 (cationic oligodeoxynucleotide binding protein).[1]
• In indirect immunofluorescence.[2]
• In Western blotting.[3]

The ExtrAvidin-R-Phycoerythrin (PE) conjugate may be used in conjunction with biotinylated reagents in the avidin/biotin labeling system in flow cytometry.

Physikalische Form
