   VMRC-21: Antarctic icefish (Chaenocephaus aceratus) BAC Library   

The Antarctic icefish (Chaenocephaus aceratus) BAC library was constructed by Andrew Stuart and Deb Tinnemore in Chris Amemiya’s laboratory at the Benaroya Research Institute at Virginia Mason. This library was designated VMRC-21. Leucocytes were obtained from a wild-caught icefish (sex unknown) from Dallman Bay in the Antarctic Peninsula by Chris Amemiya. Leucocytes were embedded in Incert agarose and high molecular weight DNA was prepared in situ in the agarose. Generation of the library closely followed the cloning approach developed in Pieter de Jong’s laboratory Osoegawa et al., 1998. Partial-digest EcoRI fragments from the appropriate size fraction were cloned into the pCCBACE1 vector (Epicentre Technologies). The ligation products were then transformed into DH10B (T1 resistant) electro-competent cells (Invitrogen). The library has been arrayed into 336 384-well microtiter dishes and has subsequently been gridded onto 22x22cm nylon high-density colony filters for screening by probe hybridization. Each hybridization membrane represents over 18,000 distinct BAC clones (equivalent to 48 "384-well" dishes), stamped in duplicate. Analysis of 115 randomly selected BACs via pulsed field gel electrophoresis of NotI-digested DNA indicated that the average insert size was around 168kb. The BAC library construction was funded by NIH grant HG02526 (Chris T. Amemiya, BRI) under the auspices of the NIH Resource Network.
