说明

General description

荧光素染料是最常用的荧光探针。它可以为上皮缺陷染色，分析角膜上皮的完整性。荧光素用于角膜穿孔的诊断。口服或静脉注射荧光素在荧光素血管造影术中用于检测糖尿病视网膜病变和脉络膜新生血管膜。

Application

荧光素已用于：

Caco-2电池的渗透性检测
用于测试终生荧光标准品的适用性
作为荧光团，用于在存在血红蛋白时迅速恢复荧光峰值和荧光浓度
在氧自由基吸收能力(ORAC)检测中作为荧光探针

Autoantigen BiP-Derived HLA-DR4 Epitopes Differentially Recognized by Effector and Regulatory T Cells in Rheumatoid Arthritis.

Hirofumi Shoda et al.

Arthritis & rheumatology (Hoboken, N.J.), 67(5), 1171-1181 (2015-03-18)

The balance between effector and regulatory CD4+ T cells plays a key role in the pathogenesis of rheumatoid arthritis (RA). The aim of this study was to examine whether the RA autoantigen BiP has epitopes for both effector and regulatory
