Resulting fragments were size-selected in fish family in the world with over 2000 species the range of approximately 200–800 base pairs (bp) by distributed on four continents (Helfman et al. 1997). electrophoresis through a low-melting point agarose The family includes economically and scientifically gel and purified using Prep-A-Gene (Bio-Rad) DNA important freshwater species such as carps, minnows, purification kits. Size-selected fragments were ligated barbs, and zebrafishes. Thirty-nine of the 270 or into pUC18, and heat-shock transformed into E. coli so cyprinid species that occur in North America are strain DH5α following Sambrook et al. (1989).
