Effect of Ultimate pH on Postmortem Myofibrillar Protein Degradation and Meat Quality Characteristics of Chinese Yellow Crossbreed Cattle
Figure 4
Representative Western blot of troponin-T and degradation products. Each lane was loaded with 40 μg of protein. M is the molecular weight marker. Lanes 1 to 10 represent the variability in troponin-T degradation from high, intermediate, and low pHu beef aged at 4°C for 0.5 h, 3 h, 6 h, 12 h, 24 h, 2 d, 3 d, 5 d, 7 d, and 9 d postmortem. Bands 1 and 2 = 42 and 40 kDa, Bands 3 and 4 = 38 and 36 kDa, Bands 5 and 6 = 34 and 32 kDa, Band 7 = 30 kDa, and Band 8 = 28 kDa.
