Overview

Animal data on chicken tropomyosin subunits should not change practice; leaves open relevance to human cardiac isoforms.

Structured PICO

P
Population
Chicken cardiac, skeletal, and gizzard muscles
E
Exposure
Polyacrylamide gel electrophoresis (SDS, urea, sodium borate) and immunological analysis
O
Outcome
Resolution of tropomyosins into subunits, molecular weights, and immunological propertiessurrogate

This basic science study demonstrates the heterogeneity and organ specificity of tropomyosin subunits in chicken muscles.

Cite This Study

Hayashi et al. (1977) studied this question. Polyacrylamide gel electrophoresis was evaluated on Tropomyosin subunit molecular weights and mobility. Polyacrylamide gel electrophoresis of chicken muscle tropomyosins revealed distinct subunits with apparent molecular weights ranging from 36,000 to 40,000 and specific antigenic sites.
