Immunohistochemical demonstration of beta-enolase in human skeletal muscle

We have localized beta-enolase activity in human skeletal muscle fiber using the immunohistochemical method (two-step method). The first immunoreagent was rabbit anti-human beta-enolase serum raised in New Zealand white rabbit, and the second was peroxidase conjugated staphylococcal protein A. The immunohistochemical reaction for beta-enolase was noted higher in type 2 fiber, which demonstrates the low oxidative and high glycolytic enzyme activity, than in type 1 fiber.
