YOMICS Library
The YOMICS approach takes advantage of the fact that a “draft” of the entire human genome sequence is available and, most important, that accurate annotations of the sequences of each human chromosome are being released. The knowledge of the sequence of virtually all human genes allow their physical isolation by using the well established technique of Polymerase Chain Reaction (PCR).
Oligonucleotides, annealing at the 5’ and 3’ ends of each genes, are designed and synthesized and all genes are amplified starting from a convenient source of human genes (cDNA preparations from mRNAs derived from different cells and tissues are most convenient). Once isolated, each gene is expressed using recombinant DNA technologies and the corresponding recombinant protein is purified. Finally, all human recombinant proteins thus isolated are used to immunize laboratory animals so as to obtain specific antibodies against each protein.
The overall strategy is straightforward, however, the technological challenges are remarkable. Thanks to solid Bioinformatic and High-Throughput technologies available at Primm, almost two thousands recombinant proteins were produced in a reasonable timeframe. In addition, Primm top class animal facility with a capacity of housing and treating several thousands of animals simultaneously allowed the rapid generation of polyclonal antibodies which today constitute the YOMICS collection.
In summary, our collection is pretty unique. Very likely you may find antibodies not available from other vendors simply because our approach is directed toward the uncharacterized human proteins.
During the next years, Primm plans to expand the YOMICS collection with the addition of new antibodies against human proteins. Proteins from different species will also be included. Therefore please keep visiting us from time to time to see if a new addition may be of interest to you.
