Fig. 2. Identification of parvalbumin in sheepshead muscle. Upper image is a
SyproRuby-stained SDSPAGE gel showing a pair of bands in the
1011 kDa range in red, pink and white muscle of sheepshead. The lower
image is a western blot of the same gel employing an anti-parvalbumin
antibody. All three muscle fiber types appear to express the same two
parvalbumin isoforms.
