Products
| Product Name | Catalogue Number | Description |
| Toxoplasma gondii, Grade IgG | EL-18-07 | Description: Native Toxoplasma gondii antigens are obtained by extracting and subsequently centrifuging Toxoplasma tachyzoites from infected cell cultures. Strain: RH Buffer: 1% Triton x-100, Phosphate Buffered Saline pH 7.4
|
| Toxoplasma gondii, Grade IgM | EL-18-08 | Description: Toxoplasma Antigen, IgM Grade is produced by subjecting Toxoplasma tachyzoites to membrane fractionation, which allows for surface antigen isolation, specifically Toxoplasma p30. Strain: RH Buffer: 2% N-octyt–D-glucopyranoside (OGP) in Phosphate Buffered Saline pH 7.4
|
| Rubella BR2S | EL-05-15 | Description: The predominant form of the antigen is whole virions suspended in NTE with sucrose. The preparation is free of detergent. Residual non-viral protein may come from host tissue and culture medium. Strain: HPV-77 Buffer: NTE buffer (Sodium chloride, TRIS and EDTA)
|
| Cytomegalovirus, Grade 2 | EL-01-02 | Description: This preparation contains CMV antigens from all parts of the virus cycle of replication including early and late antigens, nuclear antigen, cytoplasmic antigen, structural and non-structural proteins. The antigen is in GBS without detergent or preservative. This preparation contains residual host cellular material. Strain: AD-169 Buffer: Glycine buffered saline (GBS) pH 9.5
|
| Herpes Simplex 1, Grade 2 | EL-02-02 | Description: Herpes Simplex 1 Grade 2 antigen contains a high concentration of virus particles and components in tissue culture medium containing a low concentration of bovine serum. The preparation contains no preservative or detergent. Some residual host cellular material is present. Strain: MacIntyre Buffer: Tissue culture medium
|
| Varicella-Zoster, Grade 2 | EL-03-02 | Description: The resulting antigen preparation contains a high concentration of virus and viral components as well as some cellular material suspended in EMEM with some serum proteins. Strain: VZ-10 Buffer: EMEM
|
| EBV Viral Capsid Ag, Purified | EL-16-06 | Description: This preparation contains more than 90% virus specific protein. The predominant form of the antigen is purified protein suspended in 20mM Tris-HCl with 3M MgCl,; pH 7.4. The preparation is free of detergent. Any residual non-viral protein comes from host tissue and culture medium. The protein concentration is nominally 0.030 mg/ml. Strain: P3H3 cells infected with EBV Buffer: 20mM Tris-HCl with 3M MgCl2; pH 7.4
|
| EBV Viral Capsid Concentrate | EL-16-07 | Description: This preparation contains more than 90% virus specific protein. The predominant form of the antigen is purified protein suspended in 20mM Tris-HCl with 3M MgCl2; pH 7.4. The preparation is free of detergent. Residual non-viral protein comes from host tissue and culture medium. This preparation is a more concentrated for of EL-16-06 with a protein concentration is nominally 0.10 mg/ml. Strain: P3H3 cells infected with EBV Buffer: 20mM Tris-HCl with 3M MgCl2; pH 7.4

Frequently Asked Questions
Are your ToRCH antigen products specific to certain types of ToRCH pathogens?
Our native ToRCH antigens are used for toxoplasmosis, other (varicella-zoster virus, syphilis, and parvovirus B19), rubella virus, cytomegalovirus, and herpes simplex Virus.
For what applications are your ToRCH antigen products intended?
Our ToRCH panel antigens are used in immunodiagnostic assays including ELISA, chemiluminescent automated immunoassays, immunohistochemistry, immunofluorescence, latex agglutination, rapid tests, and flow cytometry.
They are also used as external quality controls for diagnostic assays, basic and applied research in virology, microbiology, cell biology, immunology, and pathology, and for vaccine and antiviral research and development.
What is the shelf life of your ToRCH antigens?
The shelf life of our ToRCH antigens is two years from the shipping date.
Are there options for custom concentrations or formats?
Depending on the product type, native ToRCH antigens can be ordered in 1mL, 10mL, 50mL, or 100mL.
Testimonials
Proudly Supporting Over 100+ Customers with Leading Diagnostic Solutions
Learn more about how our clients worldwide use Microbix’s product lines to enhance the way they do business.
We considered other external quality controls but selected Microbix QAPs as the best solution to support assay optimization and to significantly simplify QC procedures with minimal to no pipetting steps. Microbix’s technical expertise, product design, performance, and superior customer service are impressive. We look forward to continuing our collaboration.
Robert Martinez, VP of Business Development & Scientific Affairs
We were looking for a set of controls that fully covered the range of high-risk HPV types and Microbix is the only company to have such a portfolio. After an extensive evaluation process, we concluded the performance of Microbix QAPs are exactly what Ulisse needs and the interactions with their team are delightful.
Bruna Marini, COO
MDx testing for HPV improves cervical cancer screening by identifying those at-risk efficiently. Close monitoring of the entire HPV testing workflow is critical to realizing this healthcare goal and Microbix’s HPV QAPs have been selected to support the quality assessment monitoring of the molecular testing process, a vital part of BVO’s quality management system
Dr. Rob Schuurman, National Reference Officer for the Dutch Cervical Cancer Screening Program (BVO)
r-Biopharm is pleased that the program will be delivering world-class diagnostic testing to some of the most remote populations in Australia. It has been a privilege to work with the program’s operational team and Microbix to integrate the use of the best possible test and test-workflow controls into the program
Andreas Simons, Director, Project Management Clinical Diagnostics
We’re pleased to be employing Microbix’s innovative QAPs for this new and important EQA program. Genital ulcers are the cause of a considerable and growing burden of disease that can only be alleviated by way of accurate diagnosis and treatment
Juha Wahlstedt, Sales Director at Labquality
Microbix approached us before the pandemic started, and the relationship developed so easily and quickly that we formalized our collaboration in 2020. Along with their excellent technical capabilities, they have successfully developed relationships with many diagnostics manufacturers around the world. We are pleased that our FLOQSwabs® are their exclusive choice for their growing line of swab formatted QAPs™.
