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. Core 2A is developing tools to analyze the Glycoprotein Glycome of cells, including embryonic mouse stem cells and their differentiated products. Fractionation of tryptic glycopeptides using serial lectin affinity chromatography is being developed to classify expression by the types of glycans expressed. Separation of glycopeptides is then further accomplished by liquid chromatography, followed by mass spectrometry to catalog and identify various species. At various stages, N-linked glycans will be produced by N-glycanase treatment. The resulting peptides will be identified by their Asn to Asp conversion using LC/MS analysis. All results will be submitted to the Bioinformatics module (Core project 4) for integration with other data.

这个子项目是许多利用资源的研究子项目之一 由NIH/NCRR资助的中心拨款提供。子项目的主要支持 而子项目的主要调查员可能是由其他来源提供的， 包括其它NIH来源。 列出的子项目总成本可能 代表子项目使用的中心基础设施的估计数量， 而不是由NCRR赠款提供给子项目或子项目工作人员的直接资金。 Core 2A正在开发分析细胞糖蛋白糖组的工具，包括胚胎小鼠干细胞及其分化产物。正在开发使用系列凝集素亲和色谱法对胰蛋白酶糖肽进行分级，以通过表达的聚糖类型对表达进行分类。然后通过液相色谱法进一步完成糖肽的分离，然后通过质谱法对各种物质进行分类和鉴定。在不同阶段，将通过N-聚糖酶处理产生N-连接聚糖。将使用LC/MS分析通过其Asn至Asp转化来鉴别所得肽。所有结果将提交至生物信息学模块（核心项目4），以便与其他数据整合。
