Application
Tricine 已用于:
- 单细胞采集的聚合酶链式反应(PCR)缓冲液
- 作为泌乳素补充培养基的一种组分,用于培养乳泌乳素
- 制备萤光素酶测定试剂,用于萤火虫(萤火虫)中的萤光素酶活性测定,并作为 Triton/甘氨酰甘氨酸裂解缓冲液组分
用于分离低分子量的肽的缓冲剂组分。
General description
Tricine 这个名字来源于“tris”和“glycine”。在辐射诱导的膜损伤研究中,Tricine 和其他良好的缓冲剂是羟基自由基的有效清除剂。Tricine 被广泛用作电泳缓冲液和细胞颗粒的再悬浮。由于与甘氨酸相比,它的负电荷较低,因此迁移速度较快。它具有高离子强度,这导致更多的离子运动和更少的蛋白质运动。这有助于在较低百分比的丙烯酰胺凝胶中分离小分子量蛋白质。Tricine 也被用作尾随离子,与甘氨酸-十二烷基硫酸钠-聚丙烯酰胺凝胶电泳(SDS-PAGE)系统相比,它可以在更低的丙烯酰胺浓度下分离小分子蛋白质。

Detecting heteroplasmies in the mitochondrial DNA (mtDNA) has been a challenge for many years. In the past, Sanger sequencing was the main option to perform this analysis, however, this method could not detect low frequency heteroplasmies. Massive Parallel Sequencing (MPS)
