CHORI-250: Rhesus macaque BAC Library

The CHORI-250 Rhesus macaque BAC library has been constructed at the Children’s Hospital Oakland Research Institute, BACPAC Resources, by Dr. Baoli Zhu using the cloning techniques developed in our laboratory (Osoegawa et al., 1998).  Approximately 40 ml blood was collected by Marta L. Marthas ([email protected]) at the California Regional Primate Research Center (CRPRC) and was extracted at CHORI for the preparation of high molecular weight DNA embedded in agarose.  To prepare segment 1 of the library, the DNA was partially digested with a combination of EcoRI restriction enzyme and EcoRI methylase followed by double size fractionation using CHEF gels. Size fractionated DNA was cloned into the pTARBAC2.1 vector between the EcoRI sites. For segment 2, the DNA was partially digested with MboI followed by double size fractionation. The size fractionated DNA was cloned into the pTARBAC1.3 vector between the BamHI sites. The ligation products were transformed into DH10B (T1 resistant) electrocompetent cells (BRL Life Technologies). The library has been arrayed into 384-well microtiter dishes and gridded onto 12 22x22cm nylon high-density filter for screening by probe hybridization. Each hybridization membrane represents over 18,000 distinct rat BAC clones, stamped in duplicate. BAC library construction was funded by a grant from NIH (HG01165-06).

Information with respect to DNA source of Rhesus macaque: Local ID: MMU 25311 (A*01 and B*01 positive), male, 10 years old, healthy (10 kg), assigned to an indoor breeding colony operated under a CRPRC SPF production grant (J. Roberts, PI). The Rhesus blood donor is of Indian origin and was born at the CRPRC.

Provisional data for R. Macaque BAC library

Data on the CHORI-250 clone average insert size has been determined by Pulsed Field Gel Electrophoresis. Clone size distribution has been plotted graphically. While analyzing clones using pulse-field electrophoresis to determine the average insert size, non-insert clones containing a small deleted vector fragment consistent with sucrose resistance were observed. Further in depth characterization of the library is on going in our lab and data will be updated on our web page periodically.

A list of CHORI-250 non-recombinant clones is also available. The library is being used at the Baylor College of Medicine effort to assemble the rhesus macaque genome. Low-redundancy shotgun sequencing is done from pools of BAC clones ("row and column pools"). The derived sequences are being used to associate sequences with specific BACs and correlate these sequences & BACs with specific genomic regions of another species: the human genome. The derived BAC sequences are being used in combination with sequence data derived by the whole-genome shotgun sequencing (WGSS) effort at BCM. The combination of WGSS data and the BAC-pool derived data results in "eBAC" sequences. Please note that the WGSS sequences are being obtained from a different female indian macaque obtained by BCM from the San Antonio Regional Non-Human Primate Center. The pooled shotgun sequencing method and its implementation to map rhesus BACs relative to the human genome, has been described by Milosavljevic et al. 2005.

BAC clones mapped by "Pooled genomic indexing" of the rhesus macaque BAC library can be found on the Baylor website (www.genboree.org).
