NanoString Technologies this week expanded its microRNA product line with a multiplexed assay for profiling the mouse miRNA transcriptome.
The nCounter Mouse miRNA Expression Assay Kit enables researchers to perform multiplexed profiling of more than 600 murine and murine-associated viral miRNAs in a single tube on the firm's nCounter Analysis System.
The firm claims the assay supports direct digital detection and counting of miRNAs at single-base resolution, without the need for amplification. Seattle-based NanoString launched a human miRNA expression assay kit last year.
Tecan has launched its HydroSpeed plate washer. The system is optimized for washing cells, beads and enzyme-linked immunosorbant assays in 96- and 384-well formats. According to Tecan, the HydroSpeed offers control over wash parameters via an touchscreen interface, with drop-wise dispensing and tunable aspiration settings.
Other features include cell protection settings that support the washing of adherent and loosely adherent cells; anticlogging settings that automatically rinse and soak the wash head when the system is idle between runs; and an exchange system that allows removal and replacement of wash heads for ultrasonic cleaning.
The HydroSpeed can be used with Tecan's Connect plate stacker for the semi-automated processing of up to 50 plates, or integrated into a Freedom Evo liquid-handling platform to offer fully automated processing for cell-, bead- and ELISA-based assay workflows, the firm said.
TriLink BioTechnologies has launched its CleanAmp 7-deaza-dGTP kit for the PCR amplification of GC-rich sequences.
According to the San Diego firm, when DNA targets high in GC-content are amplified, PCR product formation can often be compromised by inadequate strand separation and the propensity for complex secondary structure formation. TriLink now provides CleanAmp 7-deaza-dGTP individually for amplification of routine GC-rich targets. It also sells its CleanAmp 7-deaza-dGTP Mix for more challenging targets with higher GC-content.
