Amersham Biosciences


Amersham Biosciences last week announced the CodeLink UniSet Mouse 20K I Bioarray. The new array contains 20,289 30-mer probes for 21,108 mouse gene transcripts derived from public mRNA sequences in the UniGene and RefSeq databases and will be available for purchase in October, the company said. Pricing details were not provided. The arrays offer 108 positive controls, 300 negative controls, and 100 housekeeping genes. The new product offers a specificity of 90 percent probe-to-target sequence identity; sensitivity of less than one transcript per cell; and a dynamic response greater than three orders of magnitude, the company said. The mouse array is an upgrade over the company’s previous 10,000-gene mouse chips.
