Cation exchange HPLC analysis of desmosines in elastin hydrolysates
Desmosine crosslinks are responsible for the elastic properties of connective tissues in lungs and cardiovascular system and are often compromised in disease states. We developed a new, fast, and simple cation exchange HPLC assay for the analysis of desmosine and isodesmosine in animal elastin. The method was validated by determining linearity, accuracy, precision, and desmosines stability and ...
متن کاملRapid analysis of hemoglobin variants by cation-exchange HPLC.
We investigated the use of a 3.5 x 0.46 cm HPLC column packed with 5-microns particles of porous (100 nm) silica coated with polyaspartic acid for hemoglobin analysis. A 13-min gradient was produced between two mobile phases. The method is capable of separating more than 35 commonly encountered hemoglobin variants within 12 min. Hemoglobin variants identified include Bart's, acetyl F, H, A1c, F...
متن کاملCation-exchange HPLC evaluated for presumptive identification of hemoglobin variants.
A battery of relatively simple tests allows the presumptive identification of hemoglobin (Hb) variants, making unnecessary structural analysis by protein chemistry methods or DNA sequencing. The primary step in this strategy involves the use of a matrix of electrophoretic mobilities obtained under various experimental conditions. This leads to an unambiguous result in approximately 90% of the c...

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولBiosynthetic Pathway of Desmosines in Elastin By GILLIAN FRANCIS, RHYS JOHN and JOHN THOMAS
1. Elastins purified by various methods from the ligamentum nuchae and the lungs of cattle of various ages were analysed for amino acid compositions and lysine-derived cross-links. 2. In fully mature elastins from adults the main cross-links were desmosine, isodesmosine and lysinonorleucine and the so-called aldol-condensation product. Trace amounts of merodesmosine were also found. 3. During t...
