结构式:

Figur1. T-cells isolated from the spleen were fluorescently stained with DiR and i.v. injected (5x10cells/mouse) into a Nu/Nu mouse. Images above taken 24hrs post injection with IVIS Spectrum  show cells homing to the spleen.


 DiR染料是亲脂性的近红外花菁荧光染料,可以用来染细胞膜和其它脂溶性生物结构。18个碳的长链插入细胞膜中从而对细胞进行染色而细胞间的染料转移可以忽略不计。DiR的发射的是近红外荧光可以穿透细胞和组织,在活体成像中用来示踪。

DIR一般对原代细胞进行荧光染色并可进行活体成像分布观察, (例如下列细胞embryonic stem cellsbone marrow derivestem cellsadiposderivestem cellslymphocytes anerythrocytes),
