A biomedically enriched collection of 7000 human ORF clones.

We report the production and availability of over 7000 fully sequence verified plasmid ORF clones representing over 3400 unique human genes. These ORF clones were derived using the human MGC collection as template and were produced in two formats: with and without stop codons. Thus, this collection supports the production of either native protein or proteins with fusion tags added to either or both ends.

Comparing gene discovery from Affymetrix GeneChip microarrays and Clontech PCR-select cDNA subtraction: a case study.

Background: Several high throughput technologies have been employed to identify differentially regulated genes that may be molecular targets for drug discovery. Here we compared the sets of differentially regulated genes discovered using two experimental approaches: a subtracted suppressive hybridization (SSH) cDNA library methodology and Affymetrix GeneChip technology. In this "case study" we explored the transcriptional pattern changes during the in vitro differentiation of human monocytes to myeloid dendritic cells (DC), and evaluated the potential for novel gene discovery using the SSH methodology.

Nucleotide sequence based characterizations of two cryptic plasmids from the marine bacterium Ruegeria isolate PR1b.

Two plasmids, 76 and 148 kb in size, isolated from Ruegeria strain PR1b were entirely sequenced. These are the first plasmids to be characterized from this genus of marine bacteria. Sequence analysis revealed a biased distribution of function among the putative proteins encoded on the two plasmids.

A 50-kb plasmid rich in mobile gene sequences isolated from a marine micrococcus.

A 50,709-bp cryptic plasmid isolated from a marine Micrococcus has been sequenced and found to contain a number of putative mobile genetic elements. The coding regions for 11 putative transposases comprise approximately 17% of the total plasmid sequence. The majority of these transposases are located within a 13-kb cluster which includes a 1553-bp direct repeat consisting of a duplicated pair of transposase genes.
