我们已经为结构分析开发了纯化普鲁恩的条件,但这些制剂仍然含有与普恩蛋白相关的脂类。脂质POs中包括神经节苷脂和神经酰胺,最初由薄层色谱(TLC)确定;这些类别的复杂混合物现在已通过串联质谱学确定。在该资源中心,LC/MS/MS正被用来鉴定与Prion相关的类脂池的成分。这导致了100多种脂类的鉴定,并使样品之间的比较成为可能。来自不同疾病阶段的动物的进一步样本正在进行分析。
英文摘要
This subproject is one of many research subprojects utilizing the resources
provided by a Center grant funded by NIH/NCRR. Primary support for the subproject
and the subproject's principal investigator may have been provided by other sources,
including other NIH sources. The Total Cost listed for the subproject likely
represents the estimated amount of Center infrastructure utilized by the subproject,
not direct funding provided by the NCRR grant to the subproject or subproject staff.
We have developed conditions to purify prions for structural analysis, but these preparations still contain lipids that associate with the prion protein. Included in the lipid poos are gangliosides and ceramides, which were initially assigned by thin layer chromatography (TLC); complex mixtures of these classes have now been defined by tandem mass spectrometry. At the Resource, LC/MS/MS is being used to identify the components of the prion-associated lipid pool. This has resulted in the identification of more than one hundred lipids, and has enabled comparisons between the samples. Further samples from animals with different stages of disease are being analyzed.
