Select-HA 1000 k是一種透明質(zhì)酸(HA)制劑,采用重組多殺性巴氏桿菌透明質(zhì)酸合酶通過體外合成制備,粒徑分布均勻且窄。Select-HA 1000 k和Select-HATM是Hyalose LLC的商標(biāo)。透明質(zhì)酸(HA)是一種高分子量陰離子多糖(1000 - 10000 kD),由重復(fù)二糖組成,是結(jié)締組織細(xì)胞外基質(zhì)的幾種糖胺聚糖組分之一。游離HA被肝臟吸收,在肝臟中被降解和回收。數(shù)據(jù)表明HA水平與局部炎癥和許多疾病的嚴(yán)重程度之間的關(guān)系,如B或C型肝炎、類風(fēng)濕性關(guān)節(jié)炎、肝纖維化等。儲存:-20 °C或以下。建議避免頻繁凍融等分。避免微生物或HA降解酶的污染。出版物Powered by Bioz查看Bioz 1的更多詳情。Jing W.

產(chǎn)品描述
Select-HA 1000k is a hyaluronic acid (HA) preparation of uniform and narrow size distribution prepared by in vitro synthesis using recombinant Pasteurella multocida hyaluronan synthase. Select-HA 1000k and Select-HAa?¢ is a trademark of Hyalose LLC.Hyaluronic acid (HA) is a high molecular weight anionic polysaccharide (1 000-10 000 kD) composed of repeating disaccharides and is one of several glycosaminoglycan components of the extracellular matrix of connective tissue. Free HA is taken up by the liver where it is degraded and recycled. Data indicates a relationship between HA levels local inflammation and severity of many disease such as hepatitis B or C rheumatoid arthritis liver fibrosis etc.Storage: -20 ?°C or below. Avoid frequent freeze-thaw aliquoting is recommended. Avoid contamination with microbes or HA-degrading enzymes.Publications Powered by Bioz See more details on Bioz1. Jing W.; DeAngelis P. L.
