This invention includes the generation and use of two polyclonal antibodies that specifically recognizes the phosphorylation site pThr707 of Neuroligin 4 and pThr739 of Neuroligin 1. A peptide of the site around the phosphorylation site was generated and injected into rabbits to create an immune response. Serum was collected from the rabbits that was then affinity purified. The specificity of the resulting polyclonal antibodies was then determined using biochemical techniques.
These antibodies are specific to the sites and can be used to detect phosphorylation of the amino acid at this specific site.
