Abstract:

The location of the enzymes neuron-specific enolase and nonneuronal enolase on two-dimensional gels generated from tissue samples obtained from fresh human and rat cortex has been identified. This identification is based upon the following criteria: comigration on polyacrylamide gels with the appropriate purified protein and staining on nitrocellulose protein blots of human and rat cortex using antibodies specific for each protein. The results show that our preparation of neuron-specific enolase from rat and human brain is highly pure, as only one spot is obtained on two-dimensional gels. Further, the antiserum to neuron-specific enolase is highly specific, as it reacts only with neuron-specific enolase on nitrocellulose blots derived from two-dimensional gels of cortical tissue. The location of these proteins is of interest because it positively identifies two major brain proteins on two-dimensional polyacrylamide gels of fresh cortical tissue. This information will be useful in a variety of future studies aimed at both identifying specific proteins on two-dimensional gels and observing the effects of experimental manipulations on brain and other neuronal proteins.
