  1. Typical protein yield (μg) obtained after sample fractionation using the indicated volume of lysis buffer for myoblasts, myotubes (both cultured in 75 cm2 flask, ≈2×106 cells) and AT muscle (all n = 5, mean ± SEM). The protein yields (determined by BCA assay as total volume of a fraction × protein concentration in the fraction) are representative and dependent upon the volume of buffer utilized to resuspend each fraction.
