美國Protea Biosciences  
公司致力于開發各種能夠直接分析蛋白質、代謝產物和其它生物分子的新型生物分析技術。該公司的生物分析服務部門為支持項目提供了從概念到知識的各種專業經驗和創新產品。
　

Protea的LAESI DP-1000系統利用激光燒蝕電噴霧技術（Laser Ablation Electrospray Ionization，LAESI）來鑒定組織、血液、尿液、肝細胞和菌落等生物樣品中的代謝產物、脂質、肽和蛋白質等生物分子。在無需或只需簡單制備樣品的情況下，就可以快速電離生物分子，并且在常規環境條件下將其準確地定位在特定細胞結構或組織位置。LAESI DP-1000與高分辨質譜儀聯用時，也能夠對生物分子定量。

Protea is a leader in the emerging field of Bioanalytics. The company develops new technology for the identification, characterization, and quantitation of biologically-important molecules for basic research, pharmaceutical development, and diagnostic applications.

Bioanalytics is the direct identification and characterization of the products of all living cells, including proteins, lipids, metabolites and nucleic acids. Bioanalytics is emerging as a crucial area, where new technology is needed to support the future of medical research, and virtually every other field of life science research.

We develop new bioanalytical methods that enable the direct analysis of proteins and other biomolecules, and apply our capabilities to support your laboratory's research objectives.
