Figure Lengend Snippet: Relative HSP abundances in whole skeletal muscle homogenates from young adults and older adults pre and post HIT exercise. Representative Westen blots of (A) HSP72, HSP27, and αB-crystallin and (B) phosphorylated HSP27 Ser15 (pHSP27 Ser15) and pαB-crystallin Ser59 in whole muscle homogenates from the vastus lateralis of the same individuals. Calibration curves of mixed muscle homogenates are indicated and were used to determine the relative number of given proteins (see Methods). Stain-free gels are indicative of total protein loading, and molecular weights are indicated by markers collected under white light capture without moving the membrane between that and chemiluminescence detection.
