    Planova 20N

    Industry leaders demand a robust, nonclogging virus removal filter that can handle high concentrations with minimal process optimization. The hollow-fiber design of Planova 20N exceeds that demand. Its 30-um virus-removal layer imparts superior flux-decay resistance. Since virus removal is affected by the flux decay, which in turn is the result of the process solution overwhelming the filter capacity, Planova 20N is the ideal solution for Mab applications that exceed the capacity of other filters. From 0.001 m2 to 4 m2, it is scaleable from development to manufacturing.

    Culex Automated Pharmacology System

    In pharmacokinetics studies, the ideal animal model accurately predicts what will happen in the human. Procedures that activate the HPA axis, unleashing stress hormones, have been shown to affect the absorption, distribution, and metabolism of drugs in preclinical pharmacokinetics studies. The Culex Automated Pharmacology System automates monitoring of pharmacokinetic and pharmacodynamics in rodents, hence avoiding the HPA axis effect. Because manual dosing was partly detracting from the benefits of hands-off sampling, hands-off dosing was developed. With fully automated intravenous and gastric dosing, now far better data than before is available.

    PHERAstar

    Today's high-throughput screening facilities face increasing demands to generate more information from their existing compound libraries. Multiplexed cell-based assays allow for multiple parameters to be measured within the same well hence saving time, consumable cost, and valuable test compounds. Two different multiplexed assay combinations were sequentially measured by PHERAstar, a microplate reader, in both low-volume 384- and 1,536-well plate formats. Multiplex combinations were applied to determine the method of cell death by monitoring of an apoptosis marker and cell viability. Further multiplex combinations were applied to determine if reporter gene signal correlates for cell number or cell viability. The PHERAstar microplate reader was used to record both luminescence and fluorescence, depending on the multiplex combination.

    UCOE Expression Technology

    Ubiquitous Chromatin Opening Element (UCOE) technology provides major improvements in gene expression in stable transfected mammalian cells through effects on the structure of chromatin. UCOEs prevent transgene silencing and give consistent, stable, and high-level gene expression irrespective of the chromosomal integration site. UCOEs expression elements are small DNA elements (isolated from around house-keeping genes, which need to be active most of the time), which create a transcriptionally active open chromatin environment around an integrated transgene. This maximizes its potential to be transcribed into protein, irrespective of the position of the transgene in the chromosome.

    Microcapillary Flow Cytometry

    Traditional sheath flow cytometers may require sacrificing the animal to obtain sufficient sample for multiple tests, precluding repeat bleeds on the same animal. Guava PCA and EasyCyte systems, with their sheathless, innovative microcapillary design, require only a single drop of blood (~50 uL), obtained via tail or eye bleed, for multiple tests. In one study, lymphokine knock-out mice were monitored over time for inflammation using changes in percent GR-1 positive cells. In another study, the same mice were profiled over time to determine if they showed signs of disease progression (leukemia) and were thus eligible for drug treatment.

    LightCycler 480

    Efficiency is a quantitative expression of the quality of the PCR process and is highly sensitive to many reaction variables, which can vary from run to run. In cases where PCR efficiencies differ between the target and reference and are neither identical nor optimal, true reaction efficiency must be considered during data analysis. Use of the E-method from Roche Applied Science can produce the most accurate relative quantification data by compensating for differences between target and reference-gene amplification efficiency, whether within an experiment or between experiments.
