Hormon pertumbuhan (Growth Hormone / GH) pada ikan berperan untuk memacu pertumbuhan, disamping terlibat juga dalam fungsi osmoregulasi, pengaturan keseimbangan cairan elektrolit dan proses-proses metabolisme.Metode CTAB (Cetyl Trymethyl Ammonium Bromide) digunakan untuk mengisolasi DNA sel ikan (DNA genomik) dari sirip ekor ikan mas Majalaya dan nila GIFT. Isolasi gen hormon pertumbuhan dari DNA genomik kedua jenis ikan dapat disintesis dengan primer cGH (carp Growth Hormone) dan TiGH (Tilapia Growth Hormone) menggunakan metode PCR (Polymerase Chain Reaction).Hasil elektroforegram produk amplifikasi PCR untuk sebagian gen hormon pertumbuhan ikan mas Majalaya dapat dideteksi dengan ukuran fragmen DNA sebesar 615 bp dan 349 bp. Ukuran fragmen cDNA (complementary DNA) penyandi hormon pertumbuhan ikan mas India (Indian carps) sekitar 600 bp. Fragmen DNA hormon pertumbuhan ikan nila GIFT dapat dideteksi dengan ukuran 597 bp, sedangkan pada spesies Tilapia mossambica berukuran 567 bp.

The role of growth hormone in fish are for growth promotion. They are also involved in osmoregulation function, balance regulation of liquid electrolite and correlated with metabolism processes.CTAB (Cetyl Trymethyl Ammonium Bromide) methods was used to isolate fish cell DNA (genomic DNA) from caudal fin of Majalaya carp and GIFT nile. Growth hormone gene isolates from two kinds of genomic DNA can be synthesized with primers cGH (carp Growth Hormone) and TiGH (Tilapia Growth Hormone) using PCR (Polymerase Chain Reaction) methods. Electroforegram product of the PCR amplification for partial growth hormone gene of Majalaya carp fish can be detected with DNA fragment size of 615 bp and 349 bp. cDNA fragment size encoding growth hormone of Indian carps around 600 bp. DNA fragment of growth hormone of GIFT nile tilapia can be detected with size 597 bp.
