Bulk Antisera

Having the right high-quality antisera for your in vitro diagnostic or turbidimetry immunoassays can mean the difference between success or failure, potentially costing you time and resources. When selecting a partner for your custom or bulk antisera requirements, it matters how and where your antisera are manufactured.
The way we generate antisera makes all the difference – whether you need raw antisera, IgG fraction, or affinity-purified plasma. Our antisera are consistently manufactured and quality controlled by our team of scientists at our United States facility.
Bulk Antisera from Fortis Life Sciences

High-Quality Antisera

We purify native antigens and produce both recombinant proteins and synthetic peptides in-house. That means we have complete control over their design and QC. And because we make our recombinant protein antigens, we can target proteins and protein forms that may not be commercially available.

Our Facility Meets the Highest Standards

Our manufacturing site meets or exceeds all requirements for a USDA-certified facility, and our animals are under the care and supervision of licensed veterinarians. Our Institutional Animal Care and Use Committee (IACUC) meets every six months and can review and approve any polyclonal antisera production protocols.

Bulk Antibodies and Reagents for Diagnostic Assay Manufacturing

We have a long history of supplying bulk antibodies and reagents to diagnostic assay manufacturers for many applications such as turbidimetry/nephelometry, lateral flow, and immunoassays. The following product types are available in multiple-gram and liter scales to support bulk needs, including custom conjugation, and can be tailored to meet your application-specific technical requirements:

  • IgG Fractions
  • Affinity Purified Antibodies
  • Secondary Antibodies
  • Purified Proteins

All bulk order requests can be altered to your application-specific technical requirements, ensuring customized formulations and competitive pricing. Please do not hesitate to get in contact with our team to discuss your request.
