Animal Blood Products
Advance your studies with the industry’s go-to source for consistent whole blood and blood components isolated from rabbits as well as other species including chicken, goat, pig, cattle, and more.
The whole blood we offer is sourced from local breeders to ensure quality and ethical animal treatment then further processed into specific blood products in our ISO 9001-certified facility. Because animal blood products are collected under tightly controlled, highly standardized conditions, you can count on the quality and consistency of everything we offer.

Applications
Vaccine Development
Well known and widely used in the vaccine industry, Pel-Freez enables a range of safety and efficacy assays including:
- Complement-dependent cytotoxicity assays (CDC)
- Opsonophagocytic killing assays (OPKA)
- Serum bactericidal assays (SBA)
With the ability to deliver bulk scales of consistently-performing human complement >99% depleted of background killing antibodies through our proprietary process, we can spare your teams the hassle of preparing your own complement, maximizing efficiency and productivity.
Assay Development & Validation
In addition to advancing vaccine development, Pel-Freez’s human blood products for research can support development and validation of a range of assays. You’ll find serum and plasma from healthy donors—available as pooled or individual donor samples—for fueling the development and validation of assays that analyze human blood.
And with ready-to-use complement, antibody-depleted serum, and immunoglobulins, you’ve got reliable components for vaccine safety and efficacy assays and more.
In Vitro Diagnostics (IVDs)
Our human blood products can also support development of IVDs that test for or rely on plasma, serum, or immune components. All serum and plasma is ethically obtained, fully consented and collected under IRB approved protocols, and ready for use in your IVD development program.
All other human blood products start with the same ethically collected serum and plasma and are further processed in our facility using tightly controlled and highly standardized workflows. As a result, you can be confident that the consistency, quality, and reliability of our materials can be counted on to advance your IVD program.
Frequently Asked Questions
What's the maximum lot size of animal blood products I can order?
Our typical animal blood product lot sizes range from 50 L to 200 L.
What is the anticoagulant ratio for whole bloods and plasmas?
Typical anticoagulant ratios are 9 parts blood to 1 part anticoagulant. Specific ratios are provided in the Product Datasheets and Certificates of Analysis for each product where applicable.
What is the shelf life of whole bloods?
For applications demanding fresh whole blood, we recommend usage within 5-7 days or as soon as possible after delivery. These products may be suitable for a longer period in other applications with less stringent requirements, though we suggest usage within 30 days of delivery.
Should I freeze whole bloods?
Generally, we do not recommend freezing whole bloods as the freeze-thaw process will result in red blood cell lysis. However, certain applications may call for freezing or other treatment of whole bloods or any of our other products. Our products are meant to serve as raw materials or intermediates and therefore may be used in a wide variety of end use applications.
Are blood products aseptically collected?
Yes, depending on the species and collection environment, aseptic collection techniques are practiced whenever possible. In animal collection facilities where aseptic technique may not be feasible, materials are collected as carefully as possible by highly trained technicians. Animal blood products are collected in a abattoir environment.
What buffer should I use to reconstitute gamma globulin?
The protein is more readily soluble in a saline solution. It is generally recommended to reconstitute in at least 0.2% NaCl solution BUT, each end-user must determine if that is appropriate for their application.
