Amersham this week introduced the mouse-gene microarray for its CodeLink line. The UniSet Mouse 1 Bioarray contains 10,000 probes attached to CodeLink’s 3D substrate, the company said.

Qiagen has introduced the SensiChip Human Kinase DNA Array Bar, containing 743 human kinase and phosphatase genes, the company said. The chip, developed by Qiagen and Axximas, provides all available human kinase and phosphates genes, plus related genes, a series of housekeeping genes, and other controls, on 70-mer probes, that are temperature normalized. The chip sells for $600 and is not available in the US market, the company said.

Infineon Technologies and the Max Planck Institute of Munich have created a neuro-chip, a biosensor chip that connects with living nerve cells. The chip debuted at the International Solid State Circuits Conference 2003 last week in a presentation that included data on measurements of electrical signals from live neurons.
