Application
Recommended Usage
Flow Cytometry
1-2 ug/million cells
Immunocytochemistry/ Immunofluorescence
1-2 ug/ml
Immunohistochemistry-Paraffin
1-2 ug/ml
Western Blot
1-2 ug/ml
Application Notes
Immunohistochemistry (Formalin-fixed): 1-2ug/ml for 30 min at RT. Staining of formalin-fixed tissues requires heating tissue sections in 10mM Tris with 1mM EDTA, pH 9.0, for 45 min at 95C followed by cooling at RT for 20 minutes.
Optimal dilution for a specific application should be determined.
