Analysis of three marine fish cell lines by rapd assay.
We tested the applicability of the random amplified polymorphic deoxyribonucleic acid (RAPD) analysis for identification of three marine fish cell lines FG, SPH, and RSBF, and as a possible tool to detect cross-contamination. Sixty commercial 10-mer RAPD primers were tested on the cell lines and on samples collected from individual fish. The results obtained showed that the cell lines could be identified to the correspondent species on the basis of identical patterns produced by 35-48% of the primers tested; the total mean similarity indices for cell lines versus correspondent species of individual fish ranged from 0.825 to 0.851, indicating the existence of genetic variation in these cell lines in relation to the species of their origin. Also, four primers, which gave a monomorphic band pattern within species/line, but different among the species/line, were obtained. These primers can be useful for identification of these cell lines and for characterization of the genetic variation of these cell lines in relation to the species of their origin. This supported the use of RAPD analysis as an effective tool in species identification and cross-contamination test among different cell lines.
