Kirrel3 protein detection in adult human skeletal muscle. A – Western Blot results obtained with anti-human Kirrel3 antibody directed toward intracellular region of Kirrel3 on skeletal muscle lysates obtained from adult human males at baseline, days one and two after completion of a DHR exercise protocol. S = subject B – Western blot results from blocking peptide experiment. The antibody in A was incubated with blocking peptide before being added to membrane containing skeletal muscle lysates obtained from adult human males at baseline and one and two days post completion of a DHR exercise protocol. C – A second commercial antibody directed towards the extracellular domain of Kirrel3 was used on a selection of lysates obtained from adult human male skeletal muscle day1 or 2 post completion of the downhill running exercise bout. Ponceau staining was performed on membranes to demonstrate transfer and equal protein loading.
