Figure 4From: Liver-derived endocrine IGF-I is not critical for activation of skeletal muscle protein synthesis following oral feedingRadioligand blot which demonstrates similar levels of IGF binding proteins in skeletal muscle tissue among groups in relationship to molecular weights (24–76 kD) . Approximate mobility of IGF-I binding proteins 1–6 is indicated to the left. The same amount of proteins (±3%) was loaded in all tracks determined by spectrophotometry.Back to article page
