  • SV82 polypeptide, and cosmetic composition for reducing skin wrinkles and maintaining skin elasticity comprising SV82 polypeptide as active ingredient
    Patent number: 9879060
    Abstract: A spider venom (SV) 82 polypeptide has an amino acid sequence of SEQ ID NO: 2. An SV82 polypeptide-encoding gene having a nucleotide sequence of SEQ ID NO: 1 which is optimized for E. coli codon. A recombinant vector includes the SV82 polypeptide-encoding gene, An E. coli is transformed with the recombinant vector. A method of producing SV82 polypeptide includes transforming a host cell with the recombinant vector. A cosmetic composition for reducing skin wrinkles and maintaining skin elasticity includes SV82 polypeptide as an active ingredient.

  • Method for preparing transformed cucumis melo
    Publication number: 20060168699
    Abstract: The present invention relates to a method of preparing a transformed Cucumis melo using Acrobacterium tumefaciens, more particularly, to a method for preparing a transformed Cucumis melo, which comprises the steps of: (a) inoculating a cotyledon from Cucumis melo with Agrobacterium tumefaciens harboring a suitable vector; (b) regenerating the inoculated cotyledon in a regeneration medium containing 3.0-8.0 mg/l of kinetin as growth regulator and 0.5-3.0 mg/l of IAA (Indole-3-acetic acid) and culturing the inoculated cotyledon to obtain regenerated shoots; and (c) culturing the regenerated shoots on a rooting medium to obtain the transformed Cucumis melo.
