Human Serum Off-the-Clot | EU/US Origin | sterile filtered

SeamlessBio Human Serum – Off the Clot is sourced from healthy, certified donors in the European Union or the United States under regulated and traceable conditions.
The serum is collected without anticoagulants, allowing natural clot formation before separation and 0.2 µm sterile filtration.
This process preserves a physiologically active composition of proteins, hormones, and growth factors—making it ideal for reproducible cell culture, diagnostic, and immunological applications.

This product is exclusively available as heat inactivated or gamma irradiated, ensuring biosafety and consistent performance in sensitive research and diagnostic workflows.

What is Human Serum?

Human serum is a crucial component in various laboratory applications and research. It serves as a growth supplement for cell cultures and plays a vital role in the development of vaccines and therapeutic drugs. Our Human Serum is sourced from healthy donors in both the EU and US, ensuring high quality and reliability. The serum is sterile filtered, which means it is free from contaminants, making it ideal for sensitive experiments and procedures.

Heat Inactivation vs. Gamma Irradiation

There are two main methods used to process our Human Serum: heat inactivation and gamma irradiation. Heat inactivation involves heating the serum to eliminate pathogens while preserving its biological properties. On the other hand, gamma irradiation uses ionizing radiation to achieve similar results. Both methods ensure the serum is safe for laboratory use, but you can choose based on your specific research needs.

Sizes and Applications

We offer Human Serum in two convenient sizes: 100 mL and 500 mL. This flexibility allows researchers to select the amount that best suits their projects. Applications range from cell line development to immunological studies, making our serum an essential tool in the lab. By using our high-quality Human Serum, scientists can achieve more reliable and reproducible results in their work.
