Determination of proenkephalin products in brain tissue by high-performance liquid chromatography and a modified
Journal of Pharmacological Methods
|June 1, 1985
Abstract:
A method is described for the separation of proenkephalin products using gradient high-performance liquid chromatography preceded by Sep-Pak chromatography. Samples can be assayed simply by use of a modified mouse vas deferens bioassay which is sufficiently sensitive for most applications. The preliminary Sep-Pak chromatography method excludes alpha-neoendorphin and the dynorphins and thus provides a suitable procedure for separation of prodynorphin and proenkephalin products.
