一般說明

磺酰罗丹明B(SRB)是一种亮粉色氨基甲氧杂蒽类染料。磺酰罗丹明B(SRB)测定被广泛用于 体外 细胞毒性筛选。SRB以化学计量方式与细胞的蛋白质成分结合。因此,从染色细胞中提取的染料量与细胞质量成正比。SRB还可用于细胞密度测定。

應用

磺酰罗丹明B已被用作MCF-7(人乳腺癌细胞系)细胞增殖实验的染料。

The discovery of mutant or fusion kinases that drive oncogenesis, and the subsequent approval of specific inhibitors for these enzymes, has been instrumental in the management of some cancers. However, acquired resistance remains a significant problem in the clinic, limiting

The conversion of colloidal drug carriers/polymeric nanoparticles into dry microparticulate powders (e.g., by spray-drying) is a prominent approach to overcome the aerodynamic limitations of these formulations for delivery via inhalation. However, to what extent such nano-embedded microparticles disintegrate into individual/intact

The present study is centered on molecular mechanisms of the cytoprotective effect of geranylgeraniol (GGOH) in skeletal muscle harmed by statin-associated myopathy (SAM). GGOH via autophagy induction was purportedly assumed to prevent skeletal muscle viability impaired by statins, atorvastatin (ATR)
