This MAb is highly specific to the human neurotransmitter, GABA, with a weak interaction against the β-alanine BSA-conjugate antigen, but only at the highest concentrations. There is no interaction with any other amino acid-BSA conjugates. It can be used in fluorescence microscopy and other immunohistochemical methods, as well as on frozen sections, provided they have been perfusion fixed beforehand. Glutaraldehyde must be included in the fixative of paraffin sections, if they are used. GABA coupled to BSA with glutaraldehyde is used as an immunogen for antibody production.
