应用
O -甲酚酞作为钙化介质中的组分用于钙化试验。
生化/生理作用
o -甲酚酞是一种可逆的 pH 指示剂。反向通路(红紫色至无色)的动力学是缓慢的,因此使其成为检查波纹壁管中流动模式的适当分子。也用于通过 o -甲酚酞络合酮方法比色测定钙含量。在碱性条件 (pH 10-12) 下,钙与 o -甲酚酞结合,形成红色复合物,在 570-575 nm 处有吸光度。

Hyperphosphatemia has been associated with increased mortality in chronic kidney disease but the nature of such a relation in the general population is unclear. To investigate the association between phosphate (P) levels and all-cause and cause-specific mortality, we assessed two

Gadolinium formulations, which are administered as contrast agents in magnetic resonance imaging examinations, interfere with colorimetric serum calcium determinations. We performed an in vitro study to determine the extent to which three gadolinium formulations-gadodiamide (Omniscan), gadopentetate dimeglumine (Magnevist), and gadoversetamide

In the stratum corneum, the intercellular junction made up of cadherin proteins provides the structural integrity of the framework. Ca2+ ions are known to play a key role in maintaining this junction. In this study, we hypothesized that Ca2+ chelation

Members of the peptidylarginine deiminase (PAD) family catalyse the posttranslational conversion of peptidylarginine to peptidylcitrulline. Citrullination of proteins is well described in rheumatoid arthritis (RA), and hypercitrullination of proteins may be related to inflammation in general. PAD activity has been
