Abstract:
cDNA fragment encoding neuron-specific enolase was amplified from the cDNA library of human brain. Then the fragment was cloned for expression in E. coli using the vector pET28-a. High level of neuron-specific enolase expression was confirmed by SDS-PAAG electrophoresis and immunochemical identity by immunoblot analysis. The constructed producer strain is the cheapest source of neuron-specific enolase suitable for the use in diagnostic applications.
