Abstract:
A method of preparing an antigen-immobilized immuno-fluorescence slide, the method comprising: immobilizing a C-reactive protein on a slide to prepare a protein chip; mixing an antibody that specifically binds to a target protein, with streptavidin to label the antibody with a fluorescent nanoparticle; immuno-reacting the antibody by competitive mixing, assaying with a fluorescence camera, wherein the immobilizing of the C-reactive protein on the slide comprises: modifying the slide with 3-aminopropyltrimethoxysilane to prepare a modified slide; hydrating the slide modified with 3-aminopropyltrimethoxysilane; activating the modified slide by using a glutaraldehyde solution; dissolving a C-reactive protein at a concentration of 0.01-0.5 mg/ml in a 30-70 mM phosphate buffer solution (pH 6.5-7.8) to prepare an antigen solution for immobilization; placing a petri dish comprising the slide on a spotting guide and spotting 1-100 µ„“ of the antigen solution on spotting points; and performing a reaction on the slide prepared as described above for 1-6 hours to immobilize the antigen, and an immune-fluorescence slide prepared by using the method.

Abstract:
A method for preparing a concentrated lycopene extract is provided to obtain high-concentration lycopene efficiently from watermelon by using an emulsifying solution. A concentrated lycopene extract is prepared by the steps of: (a) collecting the flesh of watermelon, grinding/centrifuging it by a chopper, a colloid mill and a homogenizer, and separating the centrifuged flesh into cake and serum; (b) putting a 0.5% Tween 20 emulsifying solution to the dried cake in a weight ratio of 20:1, and vibrating them at room temperature for 1hr to promote extraction; and (c) removing sediments through centrifuging/filtering processes. The concentrated lycopene extract is used as the ingredient of a functional food.
