Transgenic Services
HDB Functional Genetic Center (HDB-FTC) is a custom request-based platform providing full-scale service from gene cloning, making gene expression vector/targeting construct, pronuclear/blastocyst microinjection, genotyping, to characterizations of phenotypes at both in vitro and in vivo levels in the mouse, among which the last capacity/feasibility differentiates HDB-FTC from other transgenic resources.
Contents of service
Making expression vector for
producing transgenic mice,
making gene targeting
construct for producing
knockout, knockdown, and
knock-in mice, and  
constructing BAC clones Fig. 1. Generation of knockout mice by homologous recombination. A. Chimeric mice between 129/SEV ES cells (agouti) and C57BL6 (J6) blastocysts (black). B. Potential germline transmission of their pups with agouti fur color.
containing haplotype(s) or
vulnerable loci for a particular
type of disease for generating
BAC transgenic mice
 
Homologous recombination, ES cell screening, determining transgene copy number in
transgenic founder mice
Mouse breeding, mouse genotyping, and determining heterozygous/homozygous in
 
knockout/down/in mice, and hemizygous/homozygous in transgenic mice
Basic characterization of mutant mice at molecular and histological levels
Phenotypical characterization of mutant mice
in various systems including behaviors, cancer
