RNA 6000 Nano LabChip, HotScribe

Premium

Agilent Technologies and Caliper Technologies have introduced the RNA 6000 Nano LabChip kit, an automated kit for quality control of RNA. The kit, which is designed for use with the Agilent 2100 bioanalyzer, was expected to begin shipping on August 15. It allows a researcher to analyze 300 samples, and is priced at $419.

The Nano LabChip kit allows detection of as little as five nanograms of total RNA, and offers improvements over the companies’ existing RNA lab kits by including a lower marker allowing for sample alignment and permitting samples to be easily differentiated, the companies said.

The kit also includes RNA quantitation in some cases without UV or ribogreen measurements, and is designed to be less susceptible to contaminants including Phenol and genomic DNA.

Amersham Pharmacia Biotech has launched HotScribe, a first-strand cDNA radioactive labeling kit for membrane arrays. The kit requires 100 nanograms of starting mRNA, and includes both primary anchored oligo(dT) and random nonamer primers, allowing researchers to produce probes from total or purified RNA. The labeling kit has been optimized for use with the company’s Redivue nucleotides, but can be used with other formulations of 32P- or 33P-labelled dCTP, the company said.
