Purification and characterization of enolases from coho (Oncorhynchus kisutch) and chum (Oncorhynchus keta) salmon

Archives of Biochemistry and Biophysics, 1970
Abstract Enolase from two species of Pacific salmon has been isolated and characterized. Both crystalline preparations show the presence of three electrophoretically distinct enzyme forms, but while the chum salmon enolases appear in an approximate ratio of 1:3:4, the coho salmon has one predominant (95%) form and only traces of two other enolases ...

Monitoring of viruses in chum salmon (Oncorhynchus keta) migrating to Korea

Archives of Virology, 2011
It is important to investigate the prevalence of salmonid pathogens because they can affect the amount of release of salmonid fry and the migration rate of adult salmonids. In this study, routine surveys were conducted for investigating virus distribution in migrating chum salmon spawners (Oncorhynchus keta) and their offsprings at the Namdae River ...

Characterization of a protamine gene from the chum salmon (Oncorhynchus keta)

Journal of Molecular Evolution, 1988
We have cloned and sequenced a protamine gene from the chum salmon (Oncorhynchus keta). This gene sequence is highly homologous to one found in the rainbow trout (Salmo gairdneri), including the conservation of two structurally different repetitive elements.

Development of an ELISA for Chum Salmon (Oncorhynchus keta) Growth Hormone

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1997
A specific and sensitive enzyme-linked immunosorbent assay (ELISA) was developed for the measurement of low levels of serum growth hormone (GH) in chum salmon (Oncorhynchus keta). The antiserum to GH (a-rsGH) was obtained from a rabbit immunized with recombinant chum salmon GH.

Inflexibility of vertebral number in chum salmon Oncorhynchus keta

Fisheries Science, 2010
Chum salmon Oncorhynchus keta eggs from the Chitose and Shiriuchi rivers in Hokkaido, northern Japan, were incubated under identical conditions with the aim of comparing vertebral number (V N) to that reported archived data from the 1950s.

Embryonic origin and development of the corpuscles of Stannius in chum salmon (Oncorhynchus keta)

Cell & Tissue Research, 1992
An immunocytochemical technique was used to follow the embryological origin and development of the corpuscles of Stannius (CS) in the chum salmon, Oncorhynchus keta. Stanniocalcin immunoreactive (ir-) cells can be observed as early as 13 days before hatching.

Further characterization of growth hormone from the chum salmon (Oncorhynchus keta)

General and Comparative Endocrinology, 1985
This report describes the isolation of growth hormone (GH) from the chum salmon (Oncorhynchus keta) pituitary using gel, affinity, and ion exchange chromatography. Chum GH has an estimated molecular weight of 23,500 and an amino acid composition that is consistent with a vertebrate GH. The differentially charged forms of chum GH which are only apparent

The presence of androgens in salmon (Oncorhynchus Keta Walbaum

2012
The testes of chum salmon (Oncorhynchus keta Walbaum) were examined histologically and chemically to determine the source and nature of the male sex hormone. The histological examination showed that the interstitial tissue of the testis contains cells which are similar to the interstitial cells of Leydig described by other investigators. The extraction
