Basing peptide research and development , including insulin synthesis, insoluble peptide purification, stable isotope labeling technique, Multi-phosphorylation labeling technique and multi disulfide bonds technology, Bankpeptide equipped with micro scale , large scale and multi channels peptide synthesis instruments, HPLC-20A, HPLC-20AP,HPLC-30A, LC-MS and large pure water filter and other precision instruments.Due to strict quality control, Bankpeptide has introduced a number of sophisticate high performance liquid chromatograph (English abbreviation: HPLC) and advanced liquid chromatography mass spectrometry (English abbreviation: LC-MS).Liquid chromatography(LC) can effectively separate out organic component in a sample to be measured, and analyse organic matter one by one to get the organic molecular weight, structure and concentration (quantitative analysis). We used LC-MS instrumentation from 15 January 2015, and registered to the public service platform of the Hefei Science and technology innovation"scientific instrument and equipment sharing platform" (linking: http://kjpt.hfkc.gov.cn/workplatform/default.html) ,applicable to open detection.
