Detecting Latent and Active HIV Using the RainDrop® Digital PCR System  BY RainDance
Human Immunodeficiency Virus (HIV) expression has been observed at very low levels while active, and is even more difficult to detect when latent. Previous methods have involved testing for p24 antigens or antibodies (1) or RNA expression in the range of 20 to 40 copies per milliliter (2). This application note highlights the capability of the RainDrop Digital PCR system to detect active virus (RNA), latent virus (DNA), and human and viral targets together in a single reaction. In this application note, Human Universal RNA (BioChain, #R4234565-1), Xeno RNA (Cells-to-Ct kit, Life Technologies, #4386995) and de-identified samples from some of our key customers were evaluated to demonstrate the RainDrop's utility for sensitive, precise multiplex detection of HIV DNA or RNA.

High-throughput Miniaturized Quantitative PCR with the Echo® 525 Liquid Handler BY Labcyte
Quantitative PCR (qPCR) is a prevalent tool spanning many phases of drug discovery. Advances in qPCR detection to enable 384- and 1536-well microplate formats have incentivized researchers to miniaturize qPCR assays as a means to offset the costs of increasing throughput. To significantly reduce qPCR volumes and maintain data quality, the liquid handling methods employed for such low-volume transfers must be precise and accurate. Tipless, touchless acoustic droplet ejection with the Echo liquid handler eliminates the cost of disposable tips or tip-wash cycles and simplifies assay setup by eliminating dilution steps. This study utilized the Echo 525 liquid handler to assemble low-volume qPCR assays at speeds that keep pace with high-throughput demands. The results demonstrated the Echo 525 liquid handler effectively miniaturized reaction volumes for high-throughput qPCR in both 384- and 1536-well formats.

In Vitro Toxicology and Hollow Fiber Bioreactors BY FiberCell
The recent introduction of hollow fiber bioreactor cartridges represents an important advancement in the field of in vitro toxicology. Most toxicologists believe in vitro testing methods are a useful, time and cost effective tool for drug discovery but it is generally accepted that many of the available tests are not effective for examining both time and concentration, and do not closely mimic human kinetics. This is because they do not properly take into account pharmacodynamic actions (what a drug does to the body) and pharmacokinetic actions (what a body does to the drug). Recently, with the use of hollow fiber bioreactor cartridges, this has changed.

Infrared detection decreases nitrocellulose autofluorescence and improves RPPA assays signal‐to‐noise ratio over visible wavelength detection BY Innopsys
Advances in RPPA and more generally protein array technology have resulted in a rapidly growing market. Besides RPPAs there are also analytical and functional protein microarrays. Protein array applications in disease biomarker discovery and validation reflect the enormous potential of protein arrays in the field of personalized medicine. Until now the rise of protein array technology was limited by high fluorescence emitted by nitrocellulose. The InnoScan 710-IR infrared microarray scanner now allows an increased Signal to Noise Ratio and thus sensitivity of RPPAs by decreasing background fluorscence. In addition, with a high resolution of up to 3µm per pixel, it allows the acquisition of high quality images.

Miniaturization of Multiple Displacement Amplification (MDA) of Genomes from a Single Cell BY Labcyte
Advances in whole-genome amplification have enabled sequencing of DNA and RNA from a single cell, or what is commonly called Single-cell Genomics (SGC). SGC has become an invaluable approach to understanding the magnitude of genetic and epigenetic variation that occurs throughout the life of an organism. Despite the growing interest in SGC, a standardized method for sample preparation currently does not exist. However in a recent Nature Protocols article, "Obtaining genomes from uncultivated environmental microorganisms using FACS-based singlecell genomics,"1 researchers at the Department of Energy Joint Genome Institute describe an approach that can meet the throughput and sample quality required for robust whole genome amplification from a single cell. This application highlight, describes the role of the Echo liquid handler in this new approach.

Miniaturizing siRNA Transfection Using the Echo® Liquid Handler BY Labcyte
Large-scale, high-throughput siRNA experiments require a transfer system that can facilitate reliable and reproducible transfections in high-density well-plate formats, as well as effective delivery of the siRNA molecule. This study demonstrates superior performance of the Echo liquid handler compared to more traditional liquid handling methods for standard, reverse and lipid-free transfection of siRNA molecules into mammalian cells. Results of the study clearly demonstrate the ability of the Echo liquid handler to deliver comparable transfection efficiency, knock-down and cell morphology to reactions prepared using traditional pipeting methods. In fact, reactions prepared with the Echo liquid handler were miniaturized to use significantly less volume of siRNA and other reagents, and still yielded more representative inclusion intensities than traditional manual pipetting techniques. Such miniaturization can result in significant cost savings and greater confidence in the results from siRNA screening studies.

Production of Large Quantities of Mouse and Rabbit Monoclonal Antibodies using the FiberCell Systems® Inc. Bioreactor BY FiberCell
The FiberCell® Systems hollow fiber bioreactor allows the production of about 50 - 200 mg of antibody per month from standard hybridomas using the small/medium sized reactor. The advantage of this system is that antibody production can be performed in chemically defined media (no proteins at all) resulting in pure hydridoma generated antibody with no antibody contamination from fetal bovine serum or mouse ascities. The product also is harvested in a concentrated form 500 3000 μ/ml and production of the antibody can be accomplished in a standard CO2 incubator.

Production of Recombinant Proteins and Monoclonal Antibodies in Hollow Fiber Bioreactors BY FiberCell
The production of secreted products from mammalian cells such as recombinant proteins and monoclonal antibodies is generally performed in standard flask, roller or spinner culture. The typical cycle of seeding cells at a very low density in an excess of medium and then harvesting (often quite aggressively) just before the point of medium exhaustion, is itself a very unnatural system. It is only recently understood how dramatically culture conditions can affect protein quality.

Reverse Phase Protein Arrays for Cell Signaling: Using the InnoScan 710-IR scanner improves sensitivity and dynamic range. BY Innopsys
Reverse Phase Protein Arrays (RPPAs) are increasingly used to study cell signaling as they are highly multiplexed and allow precise quantification of protein of interests in biological samples. Such arrays promote automation, simplified work flow, and preserve sample. One of the principal challenges faced by RPPAs is to find the best combination of an array surface that will support high binding levels of viable protein probes, and a detection method that will provide high sensitivity and dynamic range. With the new InnoScan 710-IR scanner it is now possible to combine infrared detection with high sensitivity and quality images.

RNAi Screening in Primary Cells BY Lonza
Screening approaches involving either overexpression or RNAi-mediated down-regulation of genes have become a potent tool for identifying drug targets. Such screens require transfection of cells with e.g. cDNA or shRNA vectors or siRNA oligonucleotides. One important factor for screening success is the ability to efficiently transfect biologically relevant cells. Lonza’s Nucleofector™ Technology is a proven non-viral method for efficient transfection of primary cells, e.g. human T cells. The HT Nucleofector™ System, a 384-well platform, expands its application range to high-throughput transfections. With its fast plate processing time and easy integration into liquid handling systems it is a convenient tool for siRNA, shRNA or miRNA screens in biologically relevant cell types.
