Dojindo,DTPA酸酐/5/D033

Product Description of Amine-Reactive Biotins
DTPA 酸酐用于向具有胺基的分子或表面添加螯合功能。 添加螯合功能后,可以将金属离子如放射性同位素引入分子中。 根据 Hnatowich 博士的说法,IgG 可以使用 DTPA 酸酐用放射性铟进行标记。 DTPA 首先通过共价键与 IgG 连接,然后 In(III) 与 DTPA 紧密螯合。 已知此类放射性抗体在体外和体内与抗原结合。

Dojindo细胞分析

细胞活力和细胞毒性测定用于药物筛选和化学物质的细胞毒性测试。Dojindo开发了高度水溶性的四唑盐,称为WST。WST-8是高度稳定的WST,用于Cell Counting Kit-8(CCK-8)。由于WST-8甲maz是水溶性的,因此不会形成晶体。因此,不需要诸如MTT测定的增溶过程。此外,CCK-8的检测灵敏度高于其他四唑盐,例如MTT,XTT,MTS或WST-1。
