产品说明
一般描述
Tris(hydroxymethyl)aminomethane (Tris) has a pH buffering range between 7.0 - 9.0 and is a routine buffer in biological sciences. Tris is used majorly in combination with ethylenediaminetetraacetic acid (EDTA), especially for electrophoretic studies. It displays negligible binding towards metal in solutions.
一系列 TRIZMA 碱和 TRIZMA HCl 的预混合溶液，为 Tris 缓冲液提供常用的 pH 值。不必混合或调节 pH 值。保证精确度 ± 0.1 个 pH 单位。
应用
Trizma® hydrochloride solution has been used as a component of lysis buffer for testing on commercially available biological sample preservation paper types. It has also been used as a vehicle and for dissolving leptin in reporter gene assay studies.
