ZeptoMetrix is committed to helping your company with all your viral testing needs. We offer a large collection of virus samples and microorganisms designed to streamline testing processes for hospitals, laboratories, and doctor's offices. We continue to source new virus strains to expand our already extensive collection and offer custom product development for meet specific needs of your company’s research and development.

Viral Testing Products and Services

ZMC offers a range of viral testing formats to assist with your specific research needs. Infectious viral culture fluids are available as consumable testing material while non-infectious viral lysates and NATtrol™ products are purified by sucrose gradient centrifugation prior to inactivation to help calibrate testing machines and train technicians. For a more custom approach, we offer sucrose purified virus samples as well as custom virology services tailored to the research needs of our customers.


BK Virus

The BK virus is commonly associated with kidney transplant patients, although 80% of the population carries a latent form of the virus. ZeptoMetrix supplies hospitals, laboratories, and research institutions with samples of the BK Virus for product development, quality assurance testing, performance testing, and manufacturing.

Universal Precautions should be implemented when handling all BK virus products, even with NATtrol BK virus products which contain inactivated, intact virus samples. Additionally, BK virus Lysate samples are available for use for immunodetection of antibodies using solid-phase enzyme immunoassays, Western Blot, dot blot, and other protein-based assays.

ZeptoMetrix BK virus Culture Fluid can be utilized in nucleic acid and molecular testing, cross-reactivity studies, and other applications. Our BK Virus culture fluids are live and infectious samples and ship on dry ice. We also recommend maintaining a storage temperature of -65°C or below.


The Coronavirus was first discovered in the 1960s and to date, six separate strains are known to impact humans. Coronaviruses are unique in the degree of symptoms caused to hosts, from the common cold to the SARS virus which caused 774 deaths between 2002 and 2003.

ZeptoMetrix is dedicated to providing high-quality samples of coronavirus in various strains and formats.

Human Coronavirus NL63 Samples

Coronavirus NL63 is responsible for nearly 5% of common respiratory illnesses. As such, ZeptoMetrix has the NL63 strain available as lysate and culture fluid products for research laboratories, scientists, manufacturers and developers for a variety of applications.

Coronavirus NL63 Culture Fluid is typically used for nucleic acid / molecular testing, limit of detection studies, cross reactivity studies, and other viral-based assays.

Coronavirus NL63 Lysate is intended for research, product development, quality assurance testing,  manufacturing use as well as being utilized as an antigen as a source for the purification of viral proteins.

Our NATtrol Coronavirus NL63 stock uses our patented inactivation process to chemically render the virus non-infectious and refrigerator stable. It is ideal for evaluating the performance of nucleic acid tests to evaluate for the presence of Coronavirus RNA.

Coronavirus 229E Samples

Coronavirus 229E also has a wide range of symptoms and effects on the human body, including the common cold, pneumonia, and bronchiolitis.

Coronavirus 229E Lysate is available in 1 mg increments with custom orders available.

Coronavirus 229E Culture Fluid, unlike the lysate sample, is alive and infectious virus and requires a material transfer agreement filed before it is shipped.

The Coxsackievirus, first discovered in 1948, is a member of the enteroviruses family. Due to the wide variety of Types, ZeptoMetrix takes special care to offer multiple varieties in lysate, culture fluid, and inactivated forms. The ZeptoMetrix Coxsackievirus product listing includes Types: A01, A02, A04, A08, A09, A10, A15, A16, A21, B03, B04, B05, AND B15

Cytomegalovirus, also known as CMV, is estimated to infect over half of the adult population by age 40. Due to the impact on immunosuppressed people, ZeptoMetrix carries several strains of the cytomegalovirus in multiple forms for testing, quality assurance, manufacturing, product development, and other applications.

Our broad line of viral, bacterial, fungal, parasitic, recombinant and bacteriophage samples all follow extensive quality control/quality assurance protocols to ensure the highest quality products for our partners and customers alike.

Zika Virus

To complement its current Tropical Disease microorganism offerings, ZeptoMetrix has added strains of Zika Virus for the development and verification of molecular diagnostic assays. These strains can be used to optimize test sensitivity. Other arboviruses from the ZeptoMetrix collection, such as Dengue Virus, Yellow Fever, and Chikungunya can be used to test that an assay is specific for the Zika Virus.

For clinical laboratory use, ZeptoMetrix has treated Zika Virus with its proprietary NATtrol™ inactivation process to manufacture non-infectious, molecular testing controls and an assay range validation panel. Together, these quality controls products can be utilized to verify test performance, track variations in results, follow lot-to-lot test kit reproducibility, monitor individual operator performance and determine aberrant long-term trends in laboratory results.
