Single-quadrupole mass spectral data of α-CEHC in mitochondria and peroxisomes in response to SQ vehicle and α-tocopherol injections. Trolox was added to subcellular fraction samples from vehicle and α-tocopherol injected rats as an internal standard (see methods). α-CEHC and trolox (internal standard) in (A) a representative mitochondrial sample from a vehicle-injected rat, (B) a representative mitochondrial sample from an α-tocopherol-injected rat, (C) a representative peroxisome sample from a vehicle-injected rat and (D) a representative peroxisome sample from an α-tocopherol-injected rat. α-CEHC and trolox were determined by a single-quadrupole LC/MS using an electrospray ionization source, as described in the methods. α-CEHC (mass-to charge ratio (m/z) 277) retention time = 15.42 - 15.46 (solid line). Trolox (m/z 249) retention time = 14.4 - 14.45 (dashed line).
