摘要:
Methods are provided for quantifying the cyclin-dependent kinase inhibitor 2A protein (p16) p16 protein directly in biological samples that have been fixed in formalin by SRM/MRM mass spectrometry. A protein sample is prepared from the biological sample using, for example, the Liquid Tissue reagents and protocol and the p16 protein is quantitated in the resulting sample by quantitating in the protein sample at least one fragment peptide from p16. Peptides can be quantitated in modified or unmodified form. An example of a modified form of a p16 peptide is phosphorylation of a tyrosine, threonine, serine, and/or other amino acid residues within the peptide sequence.
摘要(中):
提供了用于通过SRM / MRM质谱法在福尔马林中固定的生物样品中直接定量细胞周期蛋白依赖性激酶抑制剂2A蛋白(p16)p16蛋白的方法。 使用例如液体组织试剂和方案从生物样品制备蛋白质样品,并通过在蛋白质样品中定量来自p16的至少一个片段肽来定量所得样品中的p16蛋白质。 肽可以以修饰或未修饰的形式进行定量。 p16肽的修饰形式的实例是肽序列内的酪氨酸,苏氨酸,丝氨酸和/或其他氨基酸残基的磷酸化。
