Acid green 50 (Lissamine Green B) is a synthetically produced organic acid dye with two aminophenyl groups. Acid green 50 is extensively used as a food dye and has a medical application as a staining agent. Due to its low toxicity and ability to stain dead and damaged cells the dye (in form of lissamine green strips) was approved as a tool for diagnosis of eye diseases associated with the damage of ocular surface epithelial cells.

Sample Use Guides

In Vivo Use Guide

For best viewing and patient comfort, acid green 50 (Lissamine Green) impregnated tip should be moistened with one or two drops of sterile irrigating or saline solution before application. Apply moistened tip to conjunctiva or fornix as required. It is recommended that the patient blink several times after application.

Route of Administration: Other

In Vitro Use Guide

Human corneal epithelial (HCE) cells were exposed to 1, 0.5, or 0.1% of acid green 50 (lissamine green) and the cells viability was studied. No observable staining of healthy HCE cells was noted with acid green 50.
