A method for improving the recovery of fluorescent aromatic compounds (FACs) from fish bile and a kit thereof
The present invention relates to a method and a kit for improving the recovery of fluorescent aromatic compounds (FACs) from fish bile. The method comprising: preparing a volume of bile sample from a fish; adding a volume of enzyme combination and a volume of distilled water to the volume of bile in...
