性能描述

assay    ≥97% (HPLC)

Used for chemiluminescence analysis of, for example, metal cations,blood,and glucococorticoids.

STABILITY / STORAGE AS SUPPLIED:
Luminol is stable at room temperature if stored protected from light. It should be re-evaluated for suitability in user application every three to five years.

SOLUBILITY / SOLUTION STABILITY:
Sigma tests the free acid at 50 mg/mL in DMSO, obtaining a clear yellow solution.Luminol free acid is comparatively insoluble in water, but is quite soluble in base. (Saturation is approximately 200 mg/mL.the sodium salt, is readily soluble in water.)1 Solutions are very sensitive to light and the presence of metal cations; typically they are only stable 8-12 hours.The sodium salt and free base forms of luminol undergo photochemical changes resulting in the formation of a series of compounds which are significantly inhibitory to enhanced chemiluminescence.5 Luminol was also shown to be thermally unstable, so luminol and its solutions should be protected from light and high temperature.

用 途： 化学发光试剂，常用于化学发光免疫分析，例如，金属阳离子和血液分析。
 
发光率检测：最适荧光波长为400nm（在60 mM K2S2O8，100 mM K2CO3，pH11.5溶液中检测化学发光率）
