Diversity of Eukaryotes and Their Genomes
Foraminifera Genome Evolution Microbial Eukaryotes Molecular Systematics Taxon sampling Tree of Life
2014/12/18
My dissertation addresses two aspects of eukaryotic evolution, 1) the organization of eukaryotic diversity and 2) genomic variation in Foraminifera. The bulk of eukaryotic diversity is microbial with ...
Towards the isolation of esterase and amidase catalytic antibodies: Examination of germinal center diversity by cloning and sequence analysis of genes encoding monoclonal antibodies elicited by a transition state analogue
Esterase catalytic antibodies amidase amide ester hydrolysis reaction hybrid cells B cells the TSA induced antibodies genes cells cell lines
2014/12/11
In this study, a transition state analogue (TSA) approach was employed for the isolation of catalytic antibodies with esterase or amidase activity. The TSA used in this study, phosphonamidate, mimics ...

Brewers Grain Culture Supernatant In vitro Rumen Fermentation Lactobacillus mucosae
2016/5/17
The effects of Lactobacillus mucosae (L. mucosae), a potential direct fed microbial previously isolated from the rumen of Korean native goat, on the rumen fermentation profile of brewers grain were ev...
Assessment of Genetic Diversity, Relationships and Structure among Korean Native Cattle Breeds Using Microsatellite Markers
Korean Native Cattle Breeds Microsatellite Genetic Diversity Relationships
2016/5/17
Four Korean native cattle (KNC) breeds—Hanwoo, Chikso, Heugu, and Jeju black—are entered in the Domestic Animal Diversity Information System of the United Nations Food and Agriculture Organization (FA...
