    生化试剂

    生化试剂（Biochemical reagent）是指用于生命科学研究的生物材料或有机化合物，以及临床诊断和医学研究所需的各类试剂。它们是从生物体中提取或通过化学合成得到的基本成分，主要用于生物成分的分析鉴定及生物制品的制造。

    随着生命科学的发展，生化试剂已成长为一种重要的化学试剂类别，品种繁多，达10000多种。中国市场上销售的生化试剂有2500种。由于生化试剂对温度、湿度和光照敏感，容易丧失活力且保存期较短，因此对其贮存与运输条件要求较高。例如，绝大多数酶试剂需在0～5℃下保存，而某些用于遗传工程研究的酶试剂则需要在-20℃下冷藏。

    根据生物体组织中所含物质或代谢过程中产生的物质，生化试剂可以分为氨基酸、多肽、蛋白质、核苷酸、核酸、酶、辅酶、糖类、酯类和激素等。此外，按生物学研究的需求，它们还可细分为电泳试剂、色谱试剂、免疫试剂、标记试剂以及组织化学试剂等。

    不同用途的生化试剂对纯度和技术要求各不相同。例如，酶试剂通常有粗制酶、结晶酶、多次结晶酶及不含特定杂酶的酶制剂等多种形式。生产生化试剂的方法主要有三种：从生物体中分离和提纯、化学合成以及发酵等。对于生化试剂产品的技术要求包括含量、熔点、冰点、旋光度、含水量、光谱特征、折光性、密度及生物活性等。
