Description
Abstract
Using a variety of histochemical methods
-mATPase staining after alkaline and acid
preincubations, NADH-TR and a-MGPDH- we have
investigated the fibre types in porcine skeletal muscle.
The results reveal that four major fibre types -1, IIA, IIB
and II*- can be separated histochemically in
Longissimus lumborum muscle of Landrace pigs. The
histochemical properties of the muscle fibre type 11* are
very similar to that of type IIX described in other
mammals. The existence of IIX fibres in pig muscle has
been recently demonstrated by molecular biology
techniques and our results validate the use of
histochemistry (mATPase) as an easy methodology to
differentiate the three fast myosins (type 11 fibres) in pig
muscle.
