| 产品介绍 |
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。 HEPES is a biological buffer often referred to as a “Good′s” buffer. It is the most commonly used biological buffer since the pKa of HEPES is 7.31 which corresponds to the physiological pH of 7.36. HEPES is considered to be non-toxic to culture cell lines, highly water soluble and provides high solution clarity. HEPES is used in cell culture media, in biopharma buffer formulations (both upstream and downstream), and in diagnostic reagents. HEPES based buffers are used in purification bioprocesses of antibodies, bioactives, proteins and growth factors. |
