Published customer image: . Mouse anti Human CD126 antibody, clone B-R6 used for the evaluation of IL6R expression on human muscle tissue by immunofluorescence. Image caption: . Circulating IL-6 and muscle IL-6 mRNA and IL-6 receptor response muscle lengthening contractions (MLC).(1a) Average serum interleukin-6 (IL-6) concentration. Time 0 hr corresponds to pre-intervention values; all other time-points correspond to post-intervention time (hr). (1b) Relative IL-6 mRNA expression, expressed as fold-change from 0 hr. (1c) Pearson correlation of serum IL-6 concentration versus muscle IL-6 mRNA (fold-change), correlation is representative of the individual data points and presented as mean values ( )±SD (error bars). (1d) Relative IL-6 receptor (IL-6R ) mRNA expression, expressed as fold-change from 0 hr. (1e) Immunofluorescent image (40×) of a muscle cross-section triple-stained for Pax7 (red), IL-6R (green) and nuclei (DAPI = blue); IL-6R staining is apparent on the sarcolemma and satellite cell membrane. White arrow denotes one of the Pax7+ nuclei which co-localized with IL-6R (scale bar = 100 um). Values are reported as mean S.E.M. Mean values represent the mean for all 8 subjects per time-point (8 samples per time-point, 40 samples total). *p 0.05 vs. 0 hr.
