Immunogen |
Antipeptide antibodies were generated in chickens against two sequences shared between the Mouse (P10637.3) and Human (P10636.5) gene products. Neither of these sequences contain phosphorylated serine or threonine residues, so these tau antibodies recognize both the euphosphorylated and hyperphosphorylated forms of Tau. Production: After repeated injections, immune eggs were collected, and the IgY fractions were purified from the yolks. These IgY fractions were then affinity-purified using a peptide column, and the concentrations of the eluates adjusted to 0.2 mg/ml. Finally, equal volumes of both of these affinity-purified anti-peptide antibodies were mixed, and the preparation was filter-sterilized. |
