IHC: Prolonged fixation in buffered formalin can destroy the epitope. The antibody may be used at a dilution of 1:50 to 1:150 with AutoProbe III (GTX28620). Dilute according to the particular application being used. In general, the 0.05M Borate pH 8.0 containing 0.15M Sodium Chloride, 0.05% Sodium Azide, is a good diluent to use with most antibodies.
Symmetry arguments suggest that most ligands engage metals via multiple bonds. The term 'metal ligand multiple bond is often reserved for ligands of the type CR n and NR n (n = 0, 1, 2) and OR n (n = 0, 1) where R is H or an organic substituent, or pseudohalide.s a cautionary note, the classification of a metal ligand bond as being multiple bond order is ambiguous and even arbitrary because bond order is a formalism.
1 The electron pair is equally shared, but controlled by the ligand. 2  The ligand is a lewis base, and acts as an electron pair donor. The metal is the electron acceptor and a lewis acid.  Most metals form cationic ions in solutions (electron acceptors), and participate in coordination complexes.
