[Q] human chr 20-specific library

[NAKAMURA Yasukazu]

Dear Bionetters, 

 Does anyone know human chr 20-specific genomic library constructor?

 I am a graduate student in Japan. I hope to use such a construction in
order to examine long-range GC content mosaic structure along the
chromosome.

 I know ATCC have two chr 20-specific constructions using Charon 21A
(57712, 57732).  Average insert size of them are 4.0kb and 3.1kb.  I want
to use library with larger (20kb or more) insert size.

 Any information will be appliciated. Thank you in advance.

P.S. If you have some interest in long-range GC content mosaic along the
human genome, see Fukagawa et al. "A boundary of long-range G+C% mosaic
domains in the human MHC locus: pseudoautosomal boundary-like sequence
exists near the boundary" Genomics 25, 184-191 (1995).
