CombiMatrix, Affymetrix


CombiMatrix last week launched a microarray product for the H5N1 “Bird Flu” influenza A virus. The product targets identification of the virus and allows the tracking of mutations that can occur in its genetic makeup, the company said in a statement.

Affymetrix last week launched a new line of reagents, including two new cDNA synthesis kits, developed in collaboration with Invitrogen. The product offering is a sample preparation system for gene expression analysis. The One-Cycle cDNA Synthesis Kit contains reagents necessary for standard target labeling, using a minimum of 1 microgram of total RNA prior to the IVT labeling step.

The new Two-Cycle cDNA Synthesis Kit offers a streamlined procedure for preparing samples using small amounts of materials, such as biopsy or laser-capture-dissected samples, the company said. It contains enough reagents for performing two cycles of cDNA synthesis before IVT labeling. The two-cycle dDNA protocol takes 60 hours, the company said.
