Figure Lengend Snippet: Desmin phosphorylation in untrained condition at resting state (R1) in healthy young human skeletal muscle. Qualitative assessment. Pooled muscle samples ( n = 3) were fractionated in a detergent (Triton X-100) -soluble supernatant (S) and insoluble pellet (P). Samples were applied as duplicates (I, II) and membranes were incubated with antibodies raised against desmin phosphorylated at serine 31 (pS31) ( B ), 60 (pS60) ( C ), threonine 17 (pT17) ( D ), 76/77 (pT76/77) ( E ) as well as total desmin ( A , F ; two different antibodies; one monoclonal [mono] and one polyclonal [poly]). Ponceau S was used as loading standard. Vertical arrowheads indicate bands or fraction positive for respective antibody. Horizontal arrowheads indicate the analyzed bands. It is to note that the p Des S60 antibody recognized a single band which however appeared slightly above the other bands (see text). For p Des S76/77 , only bands at predicted height were considered.
