   RPCI-13: Female Human BAC Library   

  Background information

The RPCI-13 Human Female BAC Library was constructed using improved cloning techniques developed by Kazutoyo Osoegawa.  The library was generated by Baohui Zhao in our laboratory.  Construction was funded by a grant from the National Human Genome Research Institute (NHGRI, NIH) (#1R01RG01165-03).  The library was generated according to the new NHGRI/DOE "Guidance on Human Subjects in Large-Scale DNA Sequencing".

Female blood was obtained via a double-blind selection protocol.  Female blood DNA was isolated form one randomly chosen donor (out of 10 female donors) and partially digested with a combination of EcoRI and EcoRI Methylase for library segments 1&2 or either MboI or DpnII for library segments 3&4.  Size selected DNA was cloned into the pBACe3.6 vector between the EcoRI sites for library segments 1&2 or the BamHI sites for library segments 3&4.  The ligation products were transformed into DH10B electrocompetent cells (BRL Life Technologies).  The library has been arrayed into 384-well microtiter dishes and also gridded onto 22x22cm nylon high density filters for screening by probe hybridization.

The average insert size has been determined by Pulsed Field Gel Electrophoresis analysis of clones randomly chosen form plates from each segment.

The library is available as library plates, individual clones, and high-density hybridization sets (see Filter Availability)

The library is available for individual clone orders, distributed as agar-stab cultures at a not-for profit cost. See our webpage "Ordering & Pricing Information" for the costs .

The BAC library has been gridded onto 22x22cm positively charged nylon filters for hybridization screening purposes. Each filter contains 36,864 colonies which represents 18,432 independent clones spotted in duplicate in a 4x4 clone array. Clones can be identified through screening by purchasing "high-density colony" hybridization filters or by utilizing our "fee for service" "Library Screening Services" . For questions about clones and hybridization membranes, please contact BACPAC Resources ([email protected]).

With respect to the scheduling of shipments of arrayed library copies, we would like to make you aware of our policy for array distribution.

Please visit the ordering information page if you want to place an order.

Academic and commercial users interested in a copy of the BAC library should contact Pieter J. de Jong ([email protected], fax: (510) 450-7924). For hybridization membranes, please contact BACPAC Resources ([email protected]).
