Ciona savignyi BAC library
The CHORI-301 Ciona savignyi BAC library has been constructed
in our laboratory by Kazutoyo Osoegawa in collaboration with
Drs. Arend Sidow's and William
C. Smith's laboratories. DNA was isolated from sperm.
The library has been constructed using DNA which was sheared
as part of the normal liquid DNA extraction procedure. The
fragmented ends were polished by subsequent treatments with
Mung bean nuclease and T4 DNA polymerase, respectively. The
polished ends were ligated to the blunt-end side of an adapter
which has a 3'overhang. Size fractionated DNA was cloned into
the pTARBAC6 vector between the BstXI sites. 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 3 22x22cm
nylon high-density filters for screening by probe hybridization.
Each hybridization membrane represents about 18,000 distinct
Ciona savignyi BAC clones, stamped in duplicate. Library construction
was supported by sub-contracts from UC Santa Barbara through
NSF grants awarded to Dr. William C Smith.

The total library should represent approximately 14-fold
total genomic representation.
The CHORI-301 clone average insert size has been determined
by Pulsed Field Gel Electrophoresis. Clone size
distribution has been plotted graphically.
The library is available as library plates, individual clones, and high-density
hybridization sets (see Filter Availability)
Individual clones identified after screening can be obtained as stab cultures
at a cost of $80 per clone in addition to a $35 set-up charge per shipment. Shipping will be done by Federal Express and charged to the recipients account
