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.
On the other hand, covalent compounds are non-metals which are bound together, and consist of two electrons that are shared between two atoms. The molecules of an ionic compound are bonded together by the electrical attraction of the two or more ions.
