PBL InterferonSource introduces Quansys Q-Plex™ Cytokine Multiplex ELISA Arrays

New multiplexing tools for interferon detection help researchers better predict clinical outcomes

 

Piscataway, NJ – PBL InterferonSource, the world’s leading interferon expert for life science research, introduces the first Quansys Q-Plex Cytokine Multiplex ELISA arrays -- new high-throughput interferon detection kits that can save time and provide key information for drug discovery and clinical research efforts in the treatment of infectious diseases and autoimmunity.  Developed by Quansys Biosciences, the kits are currently available exclusively through PBL InterferonSource internationally and to select U.S. institutions.

 

Q-Plex kits combine interferon reagents with multiplex arrays to give researchers a better understanding of the relationship between multiple interferons and cytokines.  Examination of these relationships reveals key information that can help predict clinical outcomes based on several interferon-related biomarkers including:

  • Assessment of cytokine profiles at various points throughout the course of disease
  • Correlation of cytokine profile alterations with patient responses to therapies
  • Determination of drugs’ off-target effects

The fully quantitative ELISA-based tests contain up to 16 distinct capture antibodies in each well of a 96-well plate. Each spot is well defined and represents a distinct antibody population.  Up to 84 different samples can be assayed for all 16 unique cytokines in less than 2.5 hours.  The ability to assess multiple cytokines allows researchers to spend more time interpreting data and less time accumulating data.

 

The current Q-Plex Multiplex ELISA products include six human and four mouse cytokine arrays that:

  • Assay up to 16 cytokines in less than 2.5 hours
  • Require less than 30 µl of sample
  • Detect interferons from 30 pg/ml to less than 1 pg/ml
  • Contain low percent assay-variability; intra-assay: 8% and inter-assay: 13%
  • Compatible with serum, plasma, cell culture supernatant, homogenates, lysates, nasal lavage, tears and urine

Q-Plex Cytokine Multiplex ELISA arrays are just one of the high-performance products and assay services available from PBL InterferonSource for the life sciences community. In early 2010, PBL InterferonSource will introduce human interferon-based multiplex ELISA arrays that can simultaneously quantify the levels of Type I, II and III human interferons in a single sample. These human interferon-based kits are co-developed with Quansys Biosciences and will allow researchers to further explore complex interferon-related events.

PBL InterferonSource introduces VeriKine-HS Human Interferon Beta Serum ELISA Kit

The accurate and reproducible way to measure low level Human Interferon-Beta

 

Piscataway, NJ – PBL InterferonSource introduces VeriKine-HS Human Interferon-Beta Serum ELISA Kit. The kit allows high sensitivity and accurate measurement of human Interferon-Beta (IFN-ß) level in different sample matrices.

 

IFN-ß is a tightly regulated, early response cytokine primarily responsible for controlling viral infection. Conversely, IFN-ß aberrant expression may be associated with inflammation and autoimmunity. More sensitive assays are needed to investigate the physiological relevance of low levels of IFN-ß that may be present before viral infection or autoimmunity is observable. However, a constant challenge in interferon immunoassays is to consistently quantify the amount of IFN-ß presence in serum and plasma without interference or high background caused by heterophilic antibodies, clotting factors and/or serum proteins in the samples

 

PBL InterferonSource’s latest offering, VeriKine-HS Human Interferon-Beta Serum ELISA kit, is designed to provide IFN researchers the ability to accurately and reproducibly measure the level of IFN-ß in human serum or plasma samples. It offers low serum/plasma background detection with dose response that is better than other ELISA kits currently available to scientists (Figure 1). It has superior sensitivity enabling researchers to determine IFN-ß level to as low as 0.5 IU/ml (Figure 2). It also has an excellent percent coefficient of variation (%CV) to ensure data reproducibility.

 

VeriKine-HS Human Interferon-Beta Serum ELISA is just one of the highly accurate and reliable kits being developed every day at PBL InterferonSource for the life sciences community. To see what’s happening in the world of interferons, please contact us at info@pblassaysci.com.

Figure 1: Interferon spike-recovery tests with six serum samples where known amount of IFN-ß was added to the sera. Columns in yellow represent the average results from another manufacturer’s kit with one false positive. Columns in red are the other kit’s average results minus the false positive. Average results from PBL’s VeriKine-HS Human IFN-ß Serum kit (blue) demonstrated a superior dose response than the other kit.

 

Figure 2: In a side by side comparison with another manufacturer’s kit (red), PBL’s VeriKine-HS Human Interferon-Beta Serum ELISA kit (blue) displays greater sensitivity.
