Abstract
cDNAs were synthesized from the mRNA isolated from the mantle epithelial tissue of pearl oyster (Pinctada fucata) using reverse transcriptase and joined to a vector to give a cDNA library. A cDNA inserted in this cDNA library was caused to be expressed in Escherichia coli, for instance, to give a polypeptide corresponding to said cDNA. This polypeptide serves as a novel ingredient of cosmetic compositions, for instance.
