一般描述

我们用于生物制药加工的SAFC®系列优质原料经过严格的质量控制流程,配合记录文件和技术专长帮助我们的客户达到M-Clarity 计划规定的要求

M-Clarity 计划

缓冲液质量是生物制药工艺成功的关键,因为缓冲液几乎在每一个生产步骤中都是必不可少的。

我们广泛的缓冲材料产品线经过妥善管控,可根据您的需求量身定制。从低风险应用的非 GMP 等级,到高风险应用的 IPEC-PQG GMP标准,我们的产品可满足您的所有制造需求。

应用

HEPES是一种生物缓冲液,通常被称为“好”缓冲液。它是最常用的生物缓冲液,因为HEPES的pKa为7.31,与生理pH值7.36相对应。HEPES被认为是对培养细胞系无毒的一种物质,高度可溶于水并可为溶液提供高澄清度。

HEPES用于细胞培养基、生物制药缓冲制剂(上游和下游)以及诊断试剂。基于HEPES的缓冲液被用于纯化抗体、生物活性物质、蛋白质和生长因子的生物过程。

Triple-negative breast cancers (TNBC) are defined by a lack of expression of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (ERBB2/HER2). Although initially responsive to chemotherapy, most recurrent TNBCs develop resistance, resulting in disease progression.
