BEI Resources Goes ISO! ATCC Adds ISO Guide 34:2000 Accreditation to the ISO 9001:2000 Certification
|
|
ATCC (American Type Culture Collection), the contract manager of BEI Resources, has announced its accreditation for ISO Guide 34:2000, an international multi-industry standard specifically designed for producers of reference materials.
The ISO Guide 34 accreditation by the American Association for Laboratory Accreditation (A2LA) builds upon the earlier certification for compliance with the ISO 9001:2000 standard for quality management systems received by ATCC in 2007. Biological reference materials produced under an ISO Guide 34-accredited process have confirmed identity, well-defined characteristics and an established chain of custody — qualities essential to their effectiveness as biological standards in research and development.
In gaining ISO recognition, ATCC joins a pioneering group of biological product organizations with ISO certification. Biological materials authenticated and preserved by ATCC, such as cell lines and microorganisms, are widely used as reference materials for research and product testing.
ATCC Senior Director for Quality, Compliance and Biosafety Barry Waters, PhD, remarked,“ISO 34 accreditation represents an objective measure of confidence in the consistency and quality of ATCC reference cultures. It expands ATCC’s ability to produce internationally recognized standards for biological research and development, including certified reference materials (CRMs).”
Both ISO 9001:2000 for quality management systems and ISO Guide 34 for reference material production are among the standards promulgated by the International Organization for Standardization (ISO), a network of national standards institutes from 157 countries. ISO operates a Central Secretariat located in Geneva,Switzerland to coordinate the system.

Yersinia pestis Plasmid Profiling Assay is Now Available
|
|
The agent of bubonic plague Yersinia pestisis a NIAID Category A Priority Pathogen and likely biothreat. In support of research and product development in this area BEI Resources released a Yersinia pestis Plasmid Detection Kit (NR-9562) in April 2008.
.jpg) This assay allows the researcher to quickly identify the presence of plasmid-encoded virulence factors pPCP1, pMT1 and pCD1 and is designed to be used for characterization purposes in conjunction with standard microbiological techniques.
The assay consists of primer sets designed to specifically detect the pPCP1, pMT1 and pCD1 plasmids using standard polymerase chain reactions and includes a species-specific positive control primer set and internal positive control template.
PCR amplification of genomic DNA from Yersinia pestis displaying a pPCP1+, pMT1+, pCD1– profile (lanes 2-4 respectively). Lanes 5 and 6 are the Yersinia pestis and internal positive controls. Lane 7 is a non-template control."

Panel A. Growth of Yersinia pestis on Congo Red media showing red/orange colonies typical of pgm+ organisms. Organisms that are confirmed pgm+ and pCD1+ are considered Select Agents.
Panel B. Bacteria lacking pgm showing distinctive variations in colony morphology and reduced coloring on Congo Red media as compared to pgm+ organisms.

BEI Resources offers Overlapping Peptide Arrays for Pathogens
|
|
Custom peptides have many uses in biotechnology including epitope mapping, analyzing protein-protein interactions, and as antigens for the generation of anti-peptide antibodies. For epitope mapping, arrays consisting of a small amount of a large number of overlapping peptides are required. For the individual researcher, the generation of such a custom array of overlapping peptides for specific proteins of interest could be cost-prohibitive. For that reason, NIAID has funded BEI Resources to generate a substantial number of peptide arrays related to applications in biodefense and emerging infections. These reagents are provided free of charge (except for shipping and handling fees) for use by BEI registrants.
 Currently BEI Resources offers peptide arrays for proteins of influenza, SARS-CoV and human coronaviruses, dengue virus, hepatitis C virus, West Nile virus, hantavirus, vaccinia virus, Yersinia pestis, and Bacillus anthracis (complete list). For more information on these peptide arrays, please search our online catalog for your peptide array of interest. If you need more assistance or information about BEI Resources peptide arrays, please contact us by clicking here. |

Diarrheagenic E. coli organism panels
|
Outbreaks of foodborne disease caused by E. coli bacteria have become a serious problem in this country. E. coli organism panels, genomic DNA, and technical information are now available to support research to detect, treat, and prevent foodborne diseases.
 In February of 2008, BEI Resources released the organism panel (NR-9545) composed of representatives of the diarrheagenic E. coli pathotypes ETEC, EHEC, EPEC, EIEC and EAEC available for ordering. Genomic DNA panels from these organisms are also now available (NR-9546).
Supporting documentation includes strain propagation information and growth and morphology on certain selective and differential microbiological media (see figure to the right).

New Monkeypox Virus Real-Time PCR Assay Discriminates Monkeypox Viruses from other Orthopox Viruses
|
Monkeypox virus is transmissible to people and it has become the most important Orthopoxvirus infection in human beings since the eradication of smallpox in 1970s.
A Monkeypox Virus quantitative PCR assay (Figure 1) which preferentially detects Monkeypox viruses is now available through BEI Resources (NR-9351). This assay detects Monkepox viruses at least 1000 fold more efficiently over most other Orthopox viruses or non-Orthopox viruses (Figure 2). Since Monkeypox virus and Vaccinia share considerable homology it is a critical advantage that this assay can detect Monkeypox strains at a minimum of 100 fold more efficiently over the other Vaccinia strains.
The qPCR Monkeypox assay includes the following components: primers, FAM labeled probe, and plasmid for a standard curve. Each vial of reagent can be used for approximately 96 reactions. For technical questions about this assay or to learn more, please contact our Technical Services Department.

Ferret Reagents available through BEI Resources
|
|
In recent years, the ferret has proven to be an excellent animal model for the study of pathogenicity and transmissibility of influenza viruses (Journal of Virology 81 (13): 6890-9898 (July 2007)). Even the attachment of highly pathogenic avian influenza H5N1 in the lower respiratory track of humans is mimicked in the ferret model (Science 312 (5772): 5772 (April 21, 2006)). In like manner, ferrets are also being shown to be a good model for SARS research because they are susceptible to infection by the SARS coronavirus and can transmit the virus to uninfected animals (Nature 425: 915 (October 30, 2003)).
To support the research on these emerging infections, BEI Resources (under the direction of NIAID) will soon offer a vast array of tools for the use of the ferret model. In February of 2008, BEI Resources made available approximately 100 ferret immune gene primers that were produced under contract by the laboratory of Dr. David Kelvin (Head, Division of Experimental Therapeutics, University Health Network). In Spring 2008, BEI Resources will also offer a number of monoclonal antibodies against ferret immune antigens, also from Dr. Kelvin’s laboratory.
