New Website Redesign

As of Wednesday, August 20th we have updated the BEI Resources and MR4 websites to further optimize your online experience; making it easier, more accessible, and hopefully a bit more pleasurable to access your desired BEI and MR4 reagents. We have rolled out a new redesigned website that... 

Ebola Virus Reagents Available

BEI Resources has recently added high-level containment BSL-4 agents and associated derivatives for Ebolavirus strains Zaire, Sudan, and Bundibugyo to the BEI Resources catalog. For a list of Ebolavirus nucleic acid preparations (RNA), irradiated whole viruses, anti-Ebolavirus antibodies and expression plasmids, please click here. Live viruses, Zaire (Mayinga), Sudan (Boniface), and Bundibugyo, are only available to qualified level 4 registrants in the United States. Please contact BEI Resources customer services for more information.

Welcome NARSA Researchers!

The NARSA Strain Repository is transitioning to BEI Resources, NIAID's centralized research reagent repository in May 2014. Click here for more details.

Resources for Trypanosome Research

Trypanosomes are flagellated protozoan parasites that infect a variety of hosts. Most species are transmitted via an insect vector and cause a spectrum of devastating diseases. Trypanosoma brucei subspecies can cause African trypanosomiasis in humans resulting in >20,000 cases per year. In the Americas, Chagas disease caused by the parasite Trypanosoma cruzi affects an estimated 11 million people. Recent acquisitions in BEI Resources include cultures of T. brucei that had been adapted to grow in vitro as the procyclic form of the parasite life cycle. For researchers working on Chagas disease, we offer a luciferase-expressing transgenic strain of T. cruzi which could be useful as a tool for drug screening. Click here to see our Trypanosome research materials.

Sand Flies, Reduviids and Ticks are Here

The Vector Resource materials within BEI Resources aims to support research to discover new ways to prevent the spread of disease. Vectors—organisms that transmit pathogens to hosts—include mosquitoes, ticks, triatomine bugs, sand flies, black flies, tsetse flies, fleas, mites and certain freshwater snails. BEI Resources currently supplies mosquitoes, ticks, reduviids, sand flies and snails to researchers.

MERS-CoV virus (strain EMC/2012)

BEI Resources has the MERS-CoV virus (strain EMC/2012) available for distribution to qualified laboratories. This virus will require a BEI Level 3 registration. Middle East Respiratory Syndrome (MERS) is viral respiratory illness first reported in Saudi Arabia in 2012. It is caused by a coronavirus called MERS-CoV. Most people who have been confirmed to have MERS-CoV infection developed severe acute respiratory illness. They had fever, cough, and shortness of breath. About half of these people died. The catalog number for the MERS-CoV virus is NR-44260. You must be logged in with a valid BEI Level 3 Account to place an order. Please email our customer service department if you have any questions about obtaining the MERS-CoV virus.

2013 H7N9 Influenza Virus

The much awaited H7N9 Influenza virus is now available for your research needs. NR-44078 is a 6:2 reassortant virus produced using plasmid-based reverse genetics to contain the hemagglutinin and neuraminidase genes from A/Shanghai/1/2013 (H7N9) and internal genes from A/Puerto Rico/8/1934 (H1N1).

Chikungunya Viruses - New Strains Available

BEI Resources announces the addition of two novel BSL3 strains of Chikungunya virus (CHIKV), R-91142 and 182/25, to the catalog of available items. CHIKV is a mosquito-borne alphavirus that is mainly associated with acute febrile illness. Strains R-91142 and 182/25 CHIKV are of Asian origin. Strain 182/25 is the recently developed vaccine candidate and the only CHIKV strain to be tested in humans. Also available in the BEI Resources catalog is the CHIKV African prototype strain, S-27 and SL-15649 which was isolated in 2008 from a human serum sample collected from a febrile patient in 2006 in Sri Lanka
