Cryopreservation of chum salmon blastomeres by the straw method
Cryobiology, 2002In order to preserve genetic resources of chum salmon, Oncorhynchus keta, optimum conditions for cryopreservation of isolated blastomeres were investigated. Survival rates under various conditions were compared: the nature and the concentration of cryoprotectants before and after freezing, the seeding temperature, and the developmental stages of donor ...

Microsatellite variability in chum salmon of Primorye
Russian Journal of Genetics, 2017In this study, 12 samples of chum salmon from the southern and central parts of Primorye were studied with ten microsatellite loci. All studied localities of chum salmon of Primorye formed three main genetically different groups: (1) the Narva–Barabashevka–Ryazanovka cluster of southern Primorye, (2) Kievka River, and (3) Avvakumovka River.

Molecular Cloning and Gene Expression of Chum Salmon Cystatin
Journal of Biochemistry, 1996A salmon cystatin cDNA clone was isolated from a chum salmon cDNA library. The clone encoded a full-length extracellular-type cystatin and its signal peptide and included 5'- and 3'-untranslated regions. The deduced amino acid sequence showed a high degree of sequence similarity to mammalian cystatin C, chicken egg cystatin, and chum salmon pituitary ...

Isolation and properties of chum salmon prolactin
General and Comparative Endocrinology, 1983A highly purified prolactin (PRL) was isolated from the chum salmon pituitary by extraction with acid acetone, gel filtration on Sephadex G-25 and ion-exchange chromatography on CM-Sephadex C-25 with a yield of 1 mg/g of wet tissue. It was 10-15 times more potent than ovine PRL in sodium-retaining activity for juvenile rainbow trout adapted to 50 ...

Cardiac arrest in the spawning chum salmon
Comparative Biochemistry and Physiology Part A: Physiology, 19831. Cardiac activities of male and female spawning chum salmon were recorded simultaneously by using a radio telemetry system in combination with a wired system. 2. Heart beat stopped during a spawning bout for about 10 sec in female and for 4-6 sec in male. 3. Just before and after the temporary cardiac arrest, heart rate increased from the usual rate,

Assignment of Disulfide Linkages in Chum Salmon Stanniocalcin
Biochemical and Biophysical Research Communications, 1999Stanniocalcin (STC) is a hypocalcemic glycoprotein hormone secreted by the corpuscles of Stannius, endocrine glands unique to the bony fishes. Recently, two cDNAs encoding proteins, STC-1 and STC-2, homologous to fish STC have been identified in humans and rodents.

Gene mapping of isozyme loci in chum salmon
Journal of Heredity, 1986Recombination values were used to calculate the gene-centromere map distances for four electrophoretically detected loci, Aat3, Idh1, Idh4, and Mpi, in chum salmon (Oncorhynchus keta). We also report the results from 39 pairwise examinations for joint segregation for 10 loci in nine testcross families. Only two loci assorted nonrandomly--either Aat1 or

Isolation and characterization of chum salmon growth hormone
Archives of Biochemistry and Biophysics, 1986Two molecular forms of salmon growth hormone (sGH), sGH I and II, have been isolated from the pituitary glands of the chum salmon (Oncorhynchus keta); a two-step extraction procedure, under alkaline (pH 10) conditions, subsequent to acid-acetone extraction was employed for extraction of the sGHs. They were then purified by iso-electric precipitation at

Cysteine Protease Inhibitor in Egg of Chum Salmon
The Journal of Biochemistry, 1991Two different cysteine protease inhibitors (Forms I and II) were isolated from chum salmon egg, and their molecular weights were found to be 16,000 and 11,000, respectively. When the N-terminal amino acid sequences of Forms I and II were compared, 67% of the residues were identical but no apparent homology was found between these inhibitors and ...

DNA homologies between the rainbow trout, chum salmon and coho salmon
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1985The thermal stabilities of hybrid duplexes between the DNAs from three salmonid fish species were monitored as measures of DNA homology. The chum salmon, Oncorhynchus keta, and coho salmon, Oncorhynchus kisutch, had more DNA homology with each other than either had with the rainbow trout, Salmo gairdnerii.
