一般描述
亲和素是一种四聚体糖蛋白，是所有卵生脊椎动物的卵中的一种抗营养物质。其占鸡蛋总蛋白的0.05–0.5%。亲和素结构包含八个正交反平行β链、一个二硫键和一个糖基侧链。
应用
蛋白亲和素已被用作蛋白质结合试验中的阻断剂。它也被用于形成亲和素-生物素连接，将吉西他滨结合到微泡上，以便给药到体内模型中。
生化/生理作用
亲和素可用作抗体、荧光染料、蛋白质以及其他生物化学家感兴趣的分子标记物。亲和素与生物素（维生素H）具有高结合亲和力，可导致微生物无法获得生物素，从而抑制其增殖。亲和素的这一特性有助于其抗菌特性，并影响生物素在体内的吸收，导致维生素B7缺乏。
警告
毒性：标准处理（A）
单位定义
一个单位定义为在pH 8.9条件下，结合1 µg D-生物素所需的亲和素的量。
重悬
在复溶后存放于冰箱（4°C）。储备液在4°C条件下可稳定保存6个月。避免冻/融循环。

Chemoradiation therapy is the standard of care in muscle-invasive bladder cancer (MIBC). Although agents such as gemcitabine can enhance tumor radiosensitivity, their side effects can limit patient eligibility and treatment efficacy. This study investigates ultrasound and microbubbles for targeting gemcitabine
