Storage	The dried product should be stored in air-tight containers at ambient temperatures in the dark. A shelf-life of 5 years is proposed. No release of fluorescent material was noted when a solution of the product was incubated at pH 7.5 at 37°C for one month.
Application	Many applications of hyaluronan have appeared over the past years both in medicine (particularly its indispensable contribution to eye surgery) and in cosmetics. Fluorescein-labelled hyaluronic acid may be used as a probe for following the fate of hyaluronan in vitro. A FITC-labelled hyaluronic preparation greatly enhanced the visualisation of the permeation of the substrate through skin. Other applications of fluorescein labelled hyaluronic acid have appeared.
Description	Hyaluronic acid derived from Streptococcus equi is labelled with 5-amino-fluorescein giving a yellow product that is soluble in water and electrolytes.
