The state-of-the-art services the platform carry out include synthetic molecules characterization, protein identification/quantitation, protein-protein interaction, and protein structure, dynamics analysis, Glycosylation analysis, etc.

平台可以提供合成小分子的结构分析,蛋白(组)的定性、定量分析,蛋白-蛋白/蛋白-小分子相互作用分析、蛋白动态构象分析,糖基化分析等等服务。


 •Protein Identification service. The service identify proteins from solutions or gel bands.

蛋白鉴定分析:可覆盖胶条、溶液、beads等多种样品形式


 •Quantitative proteomics analysis. The service measure relative protein abundance using Label free, SILAC, iTRAQ and TMT techniques. We accept samples from cells, tissues and serum.

定量蛋白组学分析:包括非标记定量分析、同位素标记定量分析(SILAC, iTRAQ and TMT)。样品类型可以是细胞、组织等。


 •Protein Structure Analysis. Both chemical crosslinking MS and HDX-MS techniques are employed to study dynamic protein conformation, protein-protein interactions, and protein-small molecular interactions.

蛋白结构分析:包括交联质谱(xlink-ms)和氢氘交换质谱(HDX-MS)技术,分析蛋白-蛋白/小分子的相互作用。


•Metabolites characterization. We provide identification services for metabolites mixtures and quantification services for target metabolites.

代谢组学分析:定性、定量代谢组学质谱分析


 •Synthetic molecules characterization. We provide both identification and quantification services for synthetic molecules and oligonucleotides by using LC-MS, GCMS and NMR techniques.
