Two kinds of cross-linked polyacrylate latices with relatively narrow distribution of particle diameters, which are abbreviated to P and P/P, were synthesized by seeded emulsion co-polymerization, respectively. Butyl acrylate and 2-ethylhexy! acrylate were used as comonomers of ACR core, styrene and methyl methacrylate were employed as comonomers of ACR shell, and 1,4-butanediol diacrylate was used as cross-linking agent.

Micrococcal nuclease hypersensitive DNA fragments were either cloned directly, or mapped onto the genome by hybridization with oligo-nucleotide probes on a 244K Agilent array-CGH chip. The array-CGH mapping was confirmed for nuclease sensitivity by PCR after MNase digestion and by Southern blot analysis.
