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.

OptiCell is configured for continuous laboratory-scale production of Mabs from antibody-expressing hybridoma cell lines. Hybridoma cells are incubated in 30 mL of media, enabling the harvesting of antibodies three times a week by extracting 20 mL of the supernatant at each harvest. Under continuous hybridoma antibody production, the hybridoma cells are not disturbed, thereby eliminating the need to spin down cells at each collection of the supernatant. In this manner and due to its sterility integrity, a single OptiCell can be used in hybridoma antibody production for weeks at a time.
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.
Protein Interaction Analysis
The Biacore T100 provides unmatched performance for protein interaction analysis and is used from research through to QC. Based on the highest quality data, users can determine specificity, affinity, kinetic and thermodynamic parameters of interactions involving LMW compounds, such as potential drug candidates, through to antibodies and other biotherapeutics. One example application is antibody characterization, which can take weeks with conventional methods, but can be completed in days with Biacore T100, which allows users to select the best antibodies as research tools, assay components, or therapeutics by fully defining their interaction behavior.
The utility of the MicroRotofor cell as a separation step prior to SDS-PAGE and LC-MS/MS, an alternative separation strategy to traditional 2-DGE for proteomics research, has been proven. This strategy enables researchers to uncover low-abundance proteins for biomarker discovery. Advantages include running samples under native or denaturing conditions and separation of proteins that are insoluble in gel-based separation methods. Also, with the MicroRotofor, fractionated samples can be directly analyzed on mini gels without any concentration steps, thus speeding and facilitating the fractionation workflow prior to LC-MS/MS analysis.
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.
Neuronal Profiling BioApplication
The Neuronal Profiling BioApplication is an automated tool to easily and reliably quantitate neurite outgrowth in primary neuronal cell cultures. It performs measurements that characterize neurite outgrowth, such as neurite count, total length, and length of longest neurite with or without branches. In addition, it allows definition of subpopulations of interest, and the application characterizes these subpopulations accordingly. This application has been biologically validated, enhancing confidence in image-based data, and can be used for on-the-fly analysis of cells.

It enables stable introduction of any DNA into microbial chromosomes, thus simplifying metabolic engineering, protein expression, and identifying novel gene functions. The simplicity of this system relies on the ability to generate a Transposoma stable synaptic complex formed in vitro between a transposase and a transposon that can be electroporated into living cells. Transposomes are ideal for species that lack adequate molecular tools and have been used with over 50 different microorganisms.
BioExpress and ToxExpress System
BioExpress System and ToxExpress System are unique and innovative genomics and toxicogenomics solutions, proven to enable translational biomarker programs and map to 25/76 opportunities highlighted by the FDA Critical Path Initiative.
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.
Disposable In Vitro Production System
The in vitro system is designed to provide simple, cost-effective, smaller-scale (<100 mg) production of antibodies and other secreted proteins for the research market. The new production method uses a disposable gas permeable tissue culture bag that allows cells to live longer and grow at higher densities compared to conventional flasks or roller bottles. This system also increases gas exchange, which results in rapid cell growth, higher cell counts, and viability. Additionally, more cells and less labor translates to more antibody or other secreted proteins at less cost.

Senerga Mode of Action Platform
The Senerga Mode of Action Program dissects an immunomodulator's effect on the immune response pathway by looking at the critical interactions that underlie a number of diseases. It has been used to discover the mechanism of action of a particular drug compound, while simultaneously determining target disease(s) choice, eliminating the need to screen the compound in a range of disease models where no efficacy would have been observed. This approach allows a systematic, efficient, and focused progression toward clinical trials and can reduce the discovery timeline by several months, as well as contribute to eliminating late-phase failures.
Onyx Monolithic Capillary HPLC Columns
Onyx capillary columns, engineered by directly forming a C18 bonded monolithic silica gel rod within a 100-um I.D. glass capillary tube, are a useful solution for many capillary LC/MS/MS applications where low flow rates, high peak capacity, and increased resolution are desired. Innovative applications include using Onyx as a trap-loading column ahead of a smaller packed capillary spray tip. Customers find the high porosity, low carryover, and fritless design of the Onyx monolith ideal for such applications. In addition, due to its wide flow rate flexibility high-throughput loading at 10 uL/min can be done to minimize the total cycle time in proteomics applications.
Due to the direct correlation between ATP concentrations and energy levels in the cell, quantification of cellular ATP levels provides the most biologically relevant biomarker for monitoring cell viability. With a single-step, 10-minute protocol, the CellTiter-Glo Assay can accurately measure as few as 10 or as many as 100,000 cells per well. It has become a new standard for testing the (anti) proliferative effects of cytokines, growth factors, and new chemical entities. The large dynamic range and robustness of the technology assures consistent results.
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.
