Anwendungen

Applikationshinweise: Example of Immunocytochemistry protocol Detection of conjugated L-Glutamate in rat brain 1- Perfusion: The rat is anesthetized with sodium Pentobarbital or Nembutal and perfused intracardially through the aorta using a pump with the following solutions: Solution A: cacodylate 0.1M, sodium metabisulfite 10g/l, pH = 6.2 Solution B: cacodylate 0.1M, sodium metabisulfite 10g/l and glutaraldehyde 3-5%, pH = 7 2- Post fixation: 15 to 30 min in solution B, then 4 soft washes in Tris 0.05M with sodium metabisulfite 8.5g/l, pH 7.5 (solution C). 3- Tissue sectioning: Cryostat or vibratome sections can be used. 4- Reduction step: Sections are reduced with the solution C containing sodium borohydride (0.1M) for 10 min. Then, the sections are washed 4 times with solution C without sodium borohydride. 5- Application of anti-conjugated L-Glutamate antibody: The final dilution is 1/1,000 to 1/5,000 in solution C containing 0,1% triton X100, plus 2% of non-specific serum. A dozen of sections can be incubated with 2ml of monoclonal antibody solution overnight at 4°C. Then, after this period, the sections are washed 3 times (10 min) with solution C. N.B.: The antibody may be used at a higher dilution. The customer should explore the further antibody dilution to reduce the possibility of high background. Note that a substitution in the buffer system as used in our protocol may change the background and the antibody recognition. 6- PAP procedure: Second antibody: Sections are incubated with 1/200 dilution of goat anti-mouse in solution C for 3 hours at 20°C or 1 hour at 37°C. Then, they are washed 3 times (10 min) with solution C PAP: Sections are incubated with 1/1,000 dilution of mouse peroxidase/anti-peroxidase complex in solution C for 1 hour at 37°C. Then, they are washed 3 times (10 min) with solution C Revelation: Antibody-antigen complexes are revealed using diaminobenzidine (25mg/100ml) (or other chromogen) dissolved in Tris 0.05M and filtrated 0.05% of H 2 O 2 is added. The sections are incubated for 10 min at 20°C. Reaction is stopped by transfering sections in 5ml of Tris 0.05M. Gemacbio sells other anti-catecholamine antibodies raised in rabbit: used together, these tools could be helpful for immunocytochemistry double labelling. Recommended dilutions for Immunocytochemistry (1/1,000-1/5,000) Recommended dilutions for Western Blot (1/1,000-1/2,000)

Reinheit: The ascitic fluid was purified by ammonium sulfate precipitation
