    • The invention provides a high-throughput method for quantitating plant seed proteins, e.g. seed allergens. Such method involves obtaining a protein sample from the seed; analyzing the sample using mass spectrometry with a set of pre-designed internal standard peptides that are specific to the plant allergens; and monitoring frequencies and intensities of resulting spectra to obtain relative and absolute allergen contents in the seed. The invention also provides a system for high-throughput profiling of plant seed allergens. Such system comprises a set of pre-designed internal standard peptides that are specific to the plant seed allergens and one or more mass spectrometers.
    • 本发明提供了用于定量植物种子蛋白质的高通量方法,例如, 种子过敏原。 这种方法包括从种子获得蛋白质样品; 使用一组预先设计的对植物变应原特异的内标肽进行质谱分析样品; 并监测所得光谱的频率和强度,以获得种子中相对和绝对的变应原含量。 本发明还提供了用于植物种子过敏原的高通量分析的系统。 这种系统包括一组预先设计的对植物种子过敏原和一种或多种质谱仪特异的内标肽。
