Cellular Localization: cytoplasmic
Presentation: 20 mM tris-borate, 150 mM Sodium Chloride, dialyzed media RPMI 1640/D-MEM containing fetal bovine serum, BMC-6 carrier polysaccharides, carrier protein, and 0.05% Sodium Azide, pH 7.5.
Aliquoting Instructions: GENERAL INSTRUCTIONS: Do not dilute the entire reconstituted solution at once. Withdraw aliquots as needed with a micropipette and keep concentrated stock at 4C. Dilute according to the particular application being used. In general, the 0.05M borate pH 8.0 containing 0.15M sodium chloride, 0.02% sodium azide, is a good dilutent to use with most antibodies. GENERAL INFO: When diluting for immunohistochemistry, ELISA or western blot, make the dilution in Antibody Diluting Buffer. Avoid diluting the entire contents of the vial at once since the diluted solution may have reduced stability.
- Protocol Information:
- Staining Procedure: This antibody can be used on formalin-fixed, paraffin-embedded tissue sections. Prolonged fixation in buffered formalin can destroy the epitope. This antibody may be used at a dilution 1:50-1:100 in IHC. When using routinely processed tissues, predigestion with trypsin @ 1 mg/ml PBS, 10 mins. at 37 C. or a high temperature antigenic unmasking technique (boiling tissue sections in 10 mM citrate, pH 6.0 for 10-20 mins., folowed by cooling to RT for 10-20 mins.)) is required. The optimal conditions should be determined by the individual laboratory.
