Thermo Fisher Scientific this week announced the launch of its BioRobotix 384-well pipette tips for the Velocity11 VPrep and Bravo liquid handling workstations.

All pipette tips are certified RNA-, DNA-, RNase-, DNase-, pyrogen-, and ATP-free by an independent laboratory, and are offered in sterile and non-sterile formats. The pipette tips also have a low percent coefficient of variation specifications and antistatic trays.

Tips are lot-tested on a Velocity11 workstation, and must pass a 15-point quality control program.


Promega this week announced the availability of the pmirGLO dual-luciferase miRNA target expression vector.

The pmirGLO vector allows a luciferase reporter gene assay to measure the function of endogenous or exogenous micro RNAs. This vector also enables functional studies of sequence variations found in 3'-untranslated regions of genes often related to miRNA binding sites or other modulators of transcript stability.

These elements are cloned into the pmirGLO vector to create a transcriptional fusion to firefly luciferase.

This vector is the most recent addition to a collection of nearly 50 luciferase reporter vectors offered by Promega.


Matrical Bioscience announced this week that it is now offering laser-etched 2D barcoded storage tubes in 96- and 384- well formats.

The company said that its MatriTubes are robotics-friendly and have a well volume of 35 µL. Permanent 2D barcodes are etched on the base of each tube to track individual samples securely within the laboratory. MatriTubes are compatible with any 2D barcode reader, but give best results when used with the Scan X 2DTM.


Fluxion Biosciences this week announced the launch of the IonFlux-HT and IonFlux-16 automated patch clamp systems.

The IonFlux-HT system includes 64 amplifiers and delivers between 8,000 and 10,000 assays per day at a cost of 30 cents per data point using 384-well plates. The IonFlux-16 provides all the features of the HT system with 16 amplifiers, using a 96-well plate format. Delivering 2,000 data points per day, the IonFlux-16 system is offered at a cost that "addresses the unmet needs of many researchers who cannot afford the high price tag of current automated patch clamp systems," according to the company.

The IonFlux-16 system is available for immediate delivery. Deliveries of the IonFlux-HT system will begin in July.
