ABgene, CombiMatrix

ABgene last week announced the availability of its ABsolute Blue Master Mix for QPCR analysis in a range of pack sizes and formulations. “This flexibility reduces waste for low throughput users while offering high throughput laboratories cost-effective bulk packaging,” the company said in a statement.
According to the company, the inert blue dye in the mix does not effect the QPCR reaction. In fact, the blue color offers an “immediate check” on inaccurate dispensing. “This is an especially useful and rapid validity check when using an automated dispensing system, where variation in color may indicate a blockage in one or more of the dispensing channels,” ABgene said.

CombiMatrix Molecular Diagnostics last week launched its melanoma test, a diagnostic that it claims can discriminate malignant melanoma from benign moles.
The expression-based test, which runs on CombiMatrix’s CustomArray platform, could enable pathologists to resolve difficult-to-diagnose cases through an objective genetic analysis, CMDX parent CombiMatrix said.
