    • A method of mass spectrometry is disclosed for determining if a mutated variant of a target protein is present in a sample. The method comprises subjecting the sample to fragmentation so as to cause said target protein to fragment to form second generation fragment ions, and then mass analysing these fragment ions to obtain spectral data. The method determines if a mutated variant is present in the sample by determining that an ion in the spectral data has a mass to charge ratio that differs from the mass to charge ratio of an ion that would be observed if said target protein was a normal unmutated version of said target protein, and by an amount that corresponds to a mass difference that would be caused by the target protein being a mutated variant of said target protein. This method of analysing second generation fragment ions if a rapid and efficiency method of analysing a sample.
    • 公开了一种用于确定样品中是否存在靶蛋白的突变变体的质谱方法。 该方法包括对样品进行碎裂以使所述目标蛋白质片段化以形成第二代碎片离子,然后对这些碎片离子进行质量分析以获得光谱数据。 该方法通过确定谱数据中的离子具有与如果所述靶蛋白是正常未突变的情况下将观察到的离子的质荷比不同的质荷比的比例来确定突变变体是否存在于样品中 所述目标蛋白质的版本和对应于作为所述目标蛋白质的突变变体的靶蛋白质可能引起的质量差异的量。 还公开了应用于血红蛋白样品的电子捕获解离或电子转移解离电离技术,其中分析初级或次级离子以鉴定血红蛋白突变。

    • A roller skate having enhanced steerability and stability is disclosed The skate includes a platform for supporting a skater's foot and front and rear wheel trucks secured to the underside of the platform. A pair of front wheels is rotatably mounted in transverse axial alignment on the front wheel truck and a pair of rear wheels is rotatably mounted in transverse axial alignment on said rear wheel truck. The pairs of front and rear wheels are also in parallel axial alignment with each other and mounted on their respective wheel trucks for resiliently controlled, tilting movement about downwardly inclined longitudinal axis. In addition, a fifth wheel is rotatably mounted on the front wheel truck between the pairs of front and rear wheels and in parallel axial alignment with the wheel pairs. An additional preferred roller skate includes a single wheel rotatably mounted to the front toe plate.
