MENDEZ C, Gina et al. PURIFICATION OF IGY AGAINST THE NR3 SUBUNIT OF THE RAT BRAIN NMDA RECEPTOR. Rev. MVZ Cordoba [online]. 2008, vol. 13, n. 1, pp. 1146-1156. ISSN 0122-0268. Objective. To obtain IgY antibodies against synthetic peptides of NR3A and NR3B subunits of the rat NMDA receptor, to recognize and follow the expression of these subunits in rat brain extract at different ages. Materials and methods. By using Entrez data base and ClustalW-PBIL program for sequence alignment two peptides against NR3A
