Fig. 2From: Identification of potential serum biomarkers for breast cancer using a functional proteomics technologyDirect measurement of hexokinase activity from normal and breast cancer serum after PEP protein separation and elution (120 min). The conditions were the same as in Fig. 1, the OD readings were taken at 0 and 120 min. the OD340 nm increase from 120 min. was calculated by subtracting the value from the 0 min. reading. Boxed fractions indicated samples of interestBack to article page
