Inter-laboratory optimization of protein extraction method for the assessment of rice endogenous allergens
In rice, several allergens have been identified such as the non-specific lipid transfer protein-1, the ?-amylase/trypsin-inhibitors, the ?-globulin, the 33 kDa glyoxalase I (Gly I), the 52–63 kDa globulin, and the granule-bound starch synthetase. The goal of the present study was to define optimal rice extraction and detection methods that would allow a sensitive and reproducible measure of several classes of known rice allergens. In a three-laboratory ring-trial experiment, several protein extraction methods were first compared and analyzed by 1D multiplexed SDS-PAGE. In a second phase, an inter-laboratory validation of 2D-DIGE analysis was conducted in five independent laboratories, focusing on three rice allergens (52 kDa globulin, 33 kDa glyoxalase I, and 14–16 kDa ?-amylase/trypsin inhibitor family members). The results of the present study indicate that a combination of 1D multiplexed SDS-PAGE and 2D-DIGE methods would be recommended to quantify the various rice allergens.
