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. |
