Characterization of two POU transcription factor family members from the urochordate Oikopleura dioica.

Three POU domain containing transcription factors have been cloned from the urochordate Oikopleura dioica. Phylogenetic analysis showed that two of these (OctA1 and OctA2) are closely related members of the class II POU domain family, and one (OctB) is a member of the class III POU domain family. All three transcription factors contained a highly conserved bipartite DNA-binding POU domain with POU specific and POU homeodomains, separated by a linker region.

New resources for marine genomics: bacterial artificial chromosome libraries for the Eastern and Pacific oysters (Crassostrea virginica and C. gigas).

Large-insert genomic bacterial artificial chromosome (BAC) libraries of two culturally and economically important oyster species, Crassostrea virginica and C. gigas, have been developed as part of an international effort to develop tools and reagents that will advance our ability to conduct genetic and genomic research. A total of 73,728 C.

The antibody site in Atlantic salmon; phage display and modeling of scFv with anti-hapten binding ability.

Cloning and sequencing the cDNA of around 50 VH (VDJ) and 15 VL genes in Atlantic salmon demonstrated nine VH families (above 80% identity within each family) and one dominating but relatively diverse VL family in this species. The highest variability of the VH was seen in the CDR3, but CDR2 also expressed a modest variability. The 'whole' antibody repertoire was expressed as single chain Fv (scFv) in a phage display library by combining 12 VH and two VL specific primers (FR1/microl and FR1/CL, respectively).
