Donor Horse (Equine) Serum (Sterile Filtered)

Tissue culture scientists need to have complete confidence that the serum they use meets their specific needs, and that properly validated procedures have been used to demonstrate this. It is therefore important that all operations from the animal blood to the finished product are quality controlled and fully documented.

Thorough biological testing is carried out to assure performance and to eliminate potential biological hazards. We can offer 9CFR testing on our serum - please contact us for more information.

Animal Welfare

Careful selection, free-range conditions, extensive good pasture and stringent veterinary supervision ensures healthy stock.

Blood collection is carried out in stress-free conditions by trained and qualified personnel in accordance with the Animals (Scientific Procedures) Act 1986. Veterinary health certificates are available upon request.

Donor Horse (Equine) Serum (Sterile Filtered)  - TCS Biosciences

Consistent Quality

We maintain high quality standards in all aspects of serum production from animal husbandry, through collection to processing and packaging to ensure consistent top quality products. We recognise that traceability is of prime importance to our customers, and we are renowned for the quality of our documentation trail and our rapid response to specialist customer requirements.


Raw donor sera are stored frozen prior to filtration, which we contract out. Thawing is carried out under controlled conditions prior to homogenisation and sterile filtration to 0.1μm.

After filtration the dispensing and bottle filling processes are carried out in a state-of-the-art clean room under laminar flow.

Once labelled, the filled bottles are returned to frozen storage at -20°C without delay.

Our donor horse serum is usually supplied in 500 ml PETG bottles; however, other pack sizes can be supplied by arrangement.

Certificate of Analysis

All batches of donor horse serum come with a detailed certificate of testing. Additional tests can be carried out, should your specification require it.

Manufacturing Batch Records

A complete manufacturing record is kept for each batch, including the serum pooling record, details of the filters used, preparation of the filtration apparatus, number of bottles filled and samples taken for quality control testing.

Serum Grade Options

To meet all your laboratory needs, depending on your application, we are pleased to offer 2 grades of our 0.1µm sterile filtered Donor Horse Serum.
