Purification and Assay of Mammalian Group I and Group IIa Secretory Phospholipase A2

. They can be classified into at least four groups based on minor structural differences (1 ,2 ). In particular, two major classes of highly homologous secretory enzymes (class I and IIa) have been found in mammalian tissues. Mammalian class I PLA2 s are synthesized

Development and Clinical Application in Arthritis of a New Immunoassay for Serum Type IIA Procollagen NH2 Propeptide

RNA splicing. One form (IIA) includes and the other form (IIB) excludes a 69-amino acid cysteine-rich globular domain encoded by exon 2 in PIINP. During the process of synthesis, these N-propeptides are removed by specific proteases and released

逆流色谱在中药质量控制中的应用

研究所已从数种植物中制备了多种单体化合物，如：丹参酮I、丹参酮IIA、隐丹参酮、原儿茶酸、黄芩素、黄芩甙、灯盏乙素等。    中科院过程工程研究所已初步建立了HSCCC法指纹图谱的方法，在此基础上提出并建立了HSCCC数字化指纹谱，包含了较丰富的化学信息，准确度较高，抵消了操作因素的影响，降低了保留值的波动性；样品不需要严格预处理，分析、分离高黏度及易造成固定相吸附的样品将表现出突出优势；仪器性价比较高，适于在药材产地推广使用。
