Disclosed is an anti-obesity active extract obtained from a medicinal plant. More specifically, the extract obtained fromfoenum-graeci herba (which is a medicinal plant traditionally used in the East) can be used as an active ingredient for a raw material, a functional food, cosmetic, a crude drug, etc. for an obesity preventing or therapeutic agent because the extract can suppress the adipocyte differentiation and decrease the body weight and body fat in an obese animal, thereby suppressing fat accumulation (that is, a factor for obesity).

Disclosed are mutated genes for green fluorescence proteins and enhanced inserted YFPs expressed therefrom. The mutant proteins not only maintain their fluorescence even at 37&#xb0; C., but also exhibit about 20 times stronger fluorescence intensities in comparison to the conventional fluorescence proteins. Accordingly, the mutant fluorescence proteins of the present invention can be used as biosensors for detecting and analyzing the bioactivities of desired materials.

Enhanced inserted yellow fluorescence protein and its application

Disclosed are the methods for producing recombinant viruses using site-specific recombination in vitro. In the present invention, circular viral genomic DNAs are digested with restriction enzymes to generate a linear form viral genomic DNAs flanked by site-specific recombination sites, and then are subjected to site-specific recombination with the desired genomic materials flanked by site-specific recombination sites in vitro. According to the present invention, since the site-specific recombination mixture can be applied to host cells without further procedures of selecting the desired recombinant viral genomic DNAs, it is possible to obtain numerous recombinant viruses rapidly at the same time. Thus, the present invention can be used as a high throughput system for generating and screening hundreds or thousands of recombinant viruses.
