A manufacturing method of a light emitting device includes a light emitting element disposed over a substrate and a reflective resin disposed along the side surface of the light emitting element. The anchoring element has an engagement groove of dovetail shape that receives a similarly shaped protrusion on the assembly bar to rigidly mount the assembly bar to the anchoring element. In addition, the present invention also relates to a method for reducing the expression of the above-mentioned enzymes.
