Chickens were immunized with two synthetic peptide KLH conjugates corresponding to different regions of the NSE-2 gene product, but are shared between the Human (NP_001966, NCBI) and Rat (AAA41119) sequences. Production: After repeated injections into the hens, 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 each of these affinity-purified anti-peptide antibodies were mixed, and the preparation was filter-sterilized.
Human NSE-2 (EC 4.2.1.11) is a 47,138 dalton protein (434 amino acids) expressed in neurons of the peripheral nervous system (PNS) and central nervous system (CNS). NSE-2 catalyzes the conversion of 2-phospho-D-glycerate into phosphoenol pyruvate, and is an essential enzyme in energy metabolism in nervous tissues.Synonyms: 2-phospho-D-glycerate hydro-lyase, ENO2, Enolase 2, Gamma-enolase, NSE, Neural enolase
