Frequently Asked Questions

What is human serum used for?

Human serum is commonly used in diagnostic manufacturing, assay development, quality control testing, research applications and cell culture workflows.

What is the difference between human serum and plasma?

Human serum is collected following blood clotting and does not contain clotting factors. Human plasma is collected using anticoagulants and retains clotting proteins.

Can TCS Biosciences supply disease state plasma?

Yes. TCS Biosciences offers disease state plasma and serum materials alongside profiled donor samples to support research and diagnostic applications.

Are bespoke donor requirements available?

Our team can often support custom donor profiles and specialist sourcing requirements depending on project specifications.

Discuss Your Human Material Requirements

Whether you require normal human serum, human plasma, disease state materials, profiled donor samples or specialist human biospecimens, TCS Biosciences can help identify suitable materials to support your research, diagnostic development, assay manufacturing, quality control or cell culture application.

In addition to our standard portfolio, we also offer custom sourcing services through our established global collection network, enabling access to specialised or difficult-to-source human materials tailored to your project requirements.

We can support requests for:

  • Specific disease state samples
  • Matched sample sets (e.g. serum and plasma from the same donor)
  • Large volume batches for production or longitudinal studies
  • Demographic-specific donor profiles including age, gender or medical condition
  • Profiled donor samples and specialised clinical backgrounds
