What’s New with Luminex® xMAP® Technology Partners—August 2014

9月 2nd, 2014 / Luminex Corporation

The world of xMAP® Technology is evolving and progressing—our partners are releasing new products for use with your xMAP instruments. We want to keep you updated on the latest information provided by some of our partners.

Active Motif

Active Motif’s Histone H3 PTM Multiplex Assay is now being used to assess the effects of drug treatments and disease states on histone post-translational modifications (PTMs). Histone modifications have shown strong correlation to human pathologies, including autoimmune, neurological, inflammatory and neoplastic disorders. By utilizing the Histone H3 PTM Multiplex Kit, researchers can simultaneously assess both specific and off-target effects of compound treatments across a panel of histone modifications using only nanograms of sample. Levels of H3 pan-acetyl, H3K9ac, H3K4me3, H3K27me2 and H3S10ph histone modifications were analyzed in multiplex following pretreatment of cells with SAHA, an FDA approved cancer therapy known to increase histone acetylation. IC50 values of 4.0 µM & 4.6 µM in HeLa cells and 8.3 µM & 12.3 µM in MCF-7 cells were reported for H3K9ac and H3 pan-acetyl, respectively, which is consistent with published results. However, off-target effects were also observed from decreasing levels of H3K4me3 and H3K27me2, suggesting an effect on histone methylation that was previously unreported in single modification analysis. The Histone H3 PTM Multiplex Kit’s ability to simultaneously analyze up to 13 different histone modifications from nanogram sample amounts in a 96-well plate-based format renders a significant advantage over other methods by now providing a method for high-throughput, high-content screening of specific and off-target effects of compound treatment.

Affymetrix (eBioscience)

Branched DNA Assays

QuantiGene® Plex Assays use Luminex® xMAP® technology to simultaneously measure up to 80 genes in one well. Unlike qPCR, QuantiGene Plex utilizes branched DNA signal amplification, so RNA purification, cDNA synthesis, and PCR amplification are NOT required. Please read our new Application Guide here to see how QuantiGene® Plex can enhance your research. Additionally, if you find qPCR is restraining your gene target validation, find out how you can complete your projects faster using QuantiGene® Plex® here.

Bio-Rad

In celebration of the launch of the new Bio-Plex Pro™ RBM Human Metabolic and Hormone assays Bio-Rad invites you to download a copy of the Archives of Physiology and Biochemistry a journal dedicated to the study of metabolic disease. (Limited number of downloads available). This new installment of Bio-Plex Pro RBM Assays comprises seven distinct multiplex panels for the detection of 39 analytes, of which 15 are unique to Bio-Rad’s panels. Myriad RBM’s collaboration with Sanofi and the Population Health Research Institute (PHRI) in testing samples from the ORIGIN diabetes clinical trial was instrumental in the selection of markers in each of these panels. Benefits of Bio-Plex Pro RBM Assays include:

  • Robust performance — validated to meet rigorous analytical standards and manufactured in accordance with GMP guidelines 
·
  • Reproducible data — lot-to-lot correlation specification of R2 ≥ 0.9 based on sample testing 
·
  • Rapid results— multiplex data in just 3.5 hours through the use of magnetic beads and the fastest assay protocols

Bio-Rad also released a handy flip book that contains tips and tricks from the experts! The Bio-Plex® success guide includes expert advice to help you get the most out of your experiments. Download the assay/sample prep guide and the software and hardware guide separately or receive them as a printed flip-book.

Grifols/Progenika

Grifols improves safety of transfusions with its ID CORE XT diagnostic kit:

  • The molecular diagnostic kit available in the United States since last year has obtained CE marking
  • The diagnostic kit offers greater donor–patient compatibility by testing 37 antigens of 10 blood groups in less than 4 hours on the basis of a DNA sample
  • According to WHO data, 5% of the world’s population carry genes for hereditary blood disorders, and each year over 300,000 children are born suffering from these conditions

ID CORE XT has been developed from ID CORE+, an integral part of the BLOODchip® product line, manufactured by Progenika, a Grifols company, that incorporates the very latest technology to offer ease of use and rapid results. The diagnostic kit uses Polymerase Chain Reaction (PCR) technologies to amplify DNA samples, and this, combined with Luminex® technology, permits the precise identification of the genetic markers to be studied. In addition, the diagnostic kit incorporates BIDS XT software to control the entire process and automatically transmit the results to the laboratory computer system.
