Key result
Multiple immunofluorescence labeling rapidly identifies 3 mature equine muscle fiber types in a single cryosection.
Why the study?
Traditional fibre typing techniques in equine skeletal muscle are time consuming, prone to inaccuracy, and lack specificity for identifying all mature fibre types in a single sample.
A novel multiple immunofluorescence labelling technique allows for the rapid and specific identification of all three mature equine muscle fibre types in a single cryosection, improving upon traditional serial sectioning methods.
New single-section immunofluorescence method streamlines equine fibre typing; leaves open routine adoption pending validation in physiology and pathology studies.
Skeletal muscle is composed of a heterogeneous mixture of several fibre types, each with specific physiological properties. In equine muscle, identification of these individual fibres (fibre typing) is important for both exercise physiology and pathological studies. Traditionally, fibre typing has been achieved by adenosine triphosphatase (ATPase) histochemistry or by immunoperoxidase labelling with antibodies directed at myosin heavy chain isoforms. ATPase histochemistry can be temperamental and lacks specificity, and both techniques require staining of serial cryosections to reveal the entire fibre type compliment of a single sample, which is time consuming and prone to inaccuracy. Here we describe an immunofluorescence labelling technique that enables rapid, accurate and specific identification of the 3 mature equine muscle fibre types in a single cryosection.

Tulloch et al. (2011) studied Equine skeletal muscle fibre typing. Multiple immunofluorescence labelling technique vs. Adenosine triphosphatase (ATPase) histochemistry or immunoperoxidase labelling was evaluated on Identification of the 3 mature equine muscle fibre types in a single cryosection. A multiple immunofluorescence labelling technique enables rapid, accurate, and specific identification of the three mature equine muscle fibre types in a single cryosection.
