ExonHit Therapeutics Inc.
The world's leader in the analysis of alternative splicing

ExonHit’s SpliceArray™ microarrays constitute a novel type of microarray designed to provide high resolution gene expression profiling by generating gene expression data on both a gene and splice isoform level within the same microarray. By combining their patented approach with Agilent Techologies and Affymetrix microarray based platforms, they have created a workflow solution that yields high quality data for researchers involved with biomarker discovery in translational medicine, efficacy and safety profiling in toxicogenomics, as well as clinical development groups looking to better stratify patients in clinical trials.

The SpliceArray™ microarrays have been designed to detect and differentiate between multiple transcripts, or isoforms, that are generated from a single locus due to alternative splicing. To do so, SpliceArray™ microarrays utilize a patented combination of probes within a single microarray directed at both exon bodies and splice junctions for each splicing event. The benefit of this design is that it allows specific detection of both the long and short isoforms with a positive signal.

In addition to their existing catalogue arrays, ExonHit can design custom SpliceArray™ microarrays to meet your research needs. They can also process SpliceArray™ microarrays, as well as Agilent Technologies or Affymetrix standard catalogue arrays, using the processing procedures recommended for these platforms.

Trevigen - Cultrex® Endothelial Cell Invasion Kit
Measure early angiogenesis in vitro

The Endothelial Cell Invasion kit was created in an effort to accelerate the screening process for compounds that influence vascular endothelial cell digestion through and migration across basement extracellular membrane (BME). This kit offers a flexible, standardized, high-throughput format for quantitating the degree to which endothelial cells penetrate a BME barrier, in vitro, in response to chemoattractants and/or inhibiting compounds. This assay employs a simplified Boyden chamber-like design with an 8 micron polyethylene terephthalate (PET) membrane. Sulforaphane [1-isothiocyanato-(4R)-methylsulfinyl)-butane], a naturally occurring cancer chemopreventive agent, is provided as a control for inhibition of in vitro endothelial cell migration/invasion on Cultrex® Basment Membrane Extract. Detection of cell invasion is quantified using Calcein-AM. Calcein AM is internalized by the cells, and intracellular esterases cleave the acetomethylester (AM) moiety. Free Calcein fluoresces brightly, and this fluorescence may be used to quantitate the number of cells that have invaded or migrated using a standard curve.

Cell culture plates for tissue reconstruction in vitro

The novel ThinCert™ plates offer an innovative solution for air-lift culture with ThinCert™ cell culture inserts. The deep wells of this plate allow the application of a larger medium volume during the air-lift culture. As a consequence, fewer medium changes are required and the amount of manual work is significantly reduced. The new ThinCert™ plates incorporate notches for fixing the position of the inserted ThinCert™ cell culture insert. Thus, the inserts are guaranteed to remain in a stable position during the entire cell culture process.

Greiner Bio-One - 384 Deep Well Small Volume Polypropylene Microplates
Microplates for reduced sample consumption and assay miniaturization

In cooperation with the compound management group from Boehringer Ingelheim (Biberach, Germany), a novel well geometry was developed to enable perfect positioning for even small sample volumes and facilitate the direct transfer from storage to assay plate.

An optimal well design to directly address small sample volumes was determined in practical trials. A flat well bottom allows precise pipette tip positioning with aspiration close to the well bottom. With a standard microplate height (ANSI/SBS 2-2004) and 0.5 mm sealing rim, common plate handling processes such as heat sealing, piercing, stacking and transportation are easily employed without laborious robotic adaptation. A well geometry combination consisting of a square-top, conically tapered to a flat-bottom, renders the ideal design to utilize a high working volume with minimal waste of sample material.

Assay Designs - Hsp70 High Sensitivity ELISA Kit
For serum and plasma

Inducible heat shock protein 70 (Hsp70, or Hsp72) is a stress protein whose expression is upregulated when the cell or organism is placed under conditions of stress. Hsp70 is essential for cellular recovery, survival and maintenance of normal cellular function. As a molecular chaperone, Hsp70 prevents protein aggregation and refolds damaged proteins in response to cellular stress caused by environmental insults, pathogens and disease. Hsp70 is also released into the circulation from both necrotic and non-necrotic cells, and its levels in serum are increased by a number of stressors. Hsp70 is believed to serve as an immunological "danger signal," and measurement of Hsp70 in serum and plasma is a useful tool in the study of heat stress, infection, cardiovascular disease, exercise, and psychological stress.

  • Ultra-sensitive ELISA for the measurement of Hsp70 in serum and EDTA plasma samples
  • Fast results in just 4.5 hours
  • Highly specific for inducible Hsp70 (Hsp72)

G-Biosciences - PEROXsay™ Quantitative Peroxide Assay
A modified ferrous oxidation-xylenol orange (FOX) assay

PEROXsay™ is a colorimetric quantitative peroxide assay that measures the oxidation of ferrous (Fe2+) ions to ferric (Fe3+) ions. Peroxides react with a sugar alcohol converting it to a peroxyl radical that subsequently starts the oxidation of ferrous ions to ferric ions. The acidic pH of the PEROXsay™ assay allows the ferric (Fe3+) ion to complex with the colorimetric reagent, resulting in a change in absorbance that is proportional to the peroxide concentration. The assay has a Linear Range: 0-50µM

PEROXsay™ is suitable for the following applications; quantifying the level of protein damaging peroxides in biological solutions, measurement of lipid peroxidation of low density lipoproteins and liposomes and monitoring protein glycation.

  • The PEROXsay™ assay is designed for microtiter plates, but can be scaled up for use with 1ml cuvettes.
  • PEROXsay-LIPID™ permits the quantification of peroxides in the presence of lipids without the need for extraction steps.

Technical Report

miRtect-IT™: A Novel Method for Small RNA Detection
Tech Tip by USB Corporation

The recent discovery and characterization of small non–protein–coding regulatory RNAs, such as microRNAs (miRNAs), PIWI–associated RNAs (piRNAs and rasiRNAs), short interfering RNAs (siRNAs), trans–acting siRNAs (ta–siRNAs), and other families of short RNAs has led to a rapid expansion of research directed at elucidating their expression patterns and regulatory functions(1,2). Currently, Northern blotting is the standard method for the detection of small RNAs, because it allows direct comparison of the quantity of small RNA between different samples. However, major drawbacks of Northern blotting are time consuming procedures and poor sensitivity, especially when monitoring expression of short nucleotide sequences. Despite the
improvements in detection sensitivity provided by Locked Nucleic Acid (LNA) substituted probes(3), Northern blotting requires relatively large amounts of starting material and involves multiple handling steps (Table 1).

Another approach for small RNA detection is based on the ribonuclease protection assay (RPA), which takes advantage of liquid hybridization kinetics to improve detection sensitivity (Table 1). Both Northern blotting and RPA determine the amount of small RNA by measuring the amount of the labeled probes that are non–covalently hybridized to the small RNA, providing a relative quantification of small RNA levels. In addition, the critical experimental points that determine the assay efficiency, which are the hybridization and wash steps in the Northern Blot assay and the hybridization and ribonuclease treatment in RPA, usually require optimization because insufficient
treatment may lead to non-specific detection while excess treatment may compromise the detection sensitivity.

USB offers a novel approach for direct labeling and detection of small RNAs. The miRtect-IT™ technique takes advantage of liquid hybridization kinetics to improve detection sensitivity, but without a procedure that requires optimization. Similar to Northern blotting, miRtect-IT™ does not require specialized equipment or any amplification step, and thus allows direct and accurate measurement of specific small RNAs.
