The presence of several putative precursors for Met-enkephalin (ME) and Leu-enkephalin (LE) has been demonstrated in guinea pig striatal extracts. The major high molecular weight (Mr) species (31000) contained 9% of the total ME-immunoreactivity (IR) after digest. This species has been partially purified and characterized using sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) and nitrocellulose blotting techniques as well as highly specific radioimmunoassay (RIA) for ME, LE and ME-Arg6-Phe7.
在豚鼠纹状体提取物中已证实存在几种甲硫氨酸脑啡肽（ME）和亮氨酸脑啡肽（LE）的假定前体。主要的高分子量（Mr）物种（31000）在消化后含有总ME免疫反应性（IR）的9%。已使用十二烷基硫酸钠聚丙烯酰胺凝胶电泳（SDS-PAGE）、硝酸纤维素印迹技术以及针对ME、LE和ME-Arg6-Phe7的高度特异性放射免疫测定（RIA）对该物种进行了部分纯化和表征。
