Efficiency Evaluation of DNA Isolation Techniques in Fins of Channa marulius Using PCR Amplification and NanoDrop

Highly pure and good-quality extracted DNA is vital for PCR amplification, gene sequencing, and species identification. Seven genomic DNA isolation techniques were used to isolate the DNA from the fins of Channa marulius. The concentration and purity of isolated DNA were assessed with PCR amplification of the mitochondrial COI gene and NanoDrop. The phenol-chloroform method was found significantly (P<0.05) higher in concentration (1001 ng.ul-1) as compared to all other six evaluated DNA isolation methods. In terms of purity of isolated DNA GeneJET, the Genomic DNA Purification Kit was found significantly (P<0.05) higher among all analyzed methods. Both the Phenol chloroform method and GeneJET Genomic DNA Purification Kit were successfully used in PCR amplification. Concluding that the Phenol chloroform method and GeneJET Genomic DNA Purification Kit may be successfully used in PCR amplification. The phenol-chloroform method and GeneJET Genomic DNA Purification Kit proved the best in the extraction of DNA in high concentration with maximum yield and purity from fins of C. marulius and can be helpful to isolate DNA from fish species because a small quantity of fin tissues is required for DNA isolation without harm to fish. Moreover, data reported from this study about DNA isolation techniques may be used for molecular approaches like PCR amplification and gene sequencing of fishes.
