At BioLegend, we understand the critical steps involved in advancing your research from the lab to therapeutics. Our Cell-Vive™ GMP products are manufactured with well-defined components, providing the traceability, controllability, consistency, and safety required in cell processing and downstream manufacturing needs.

 

This page offers an overview of the different quality grades of our ancillary reagents. The formulation you choose will depend on your intended application, experimental goals, and regulatory compliance requirements. For assistance on specific products and choosing reagents for your application, please contact BioLegend Technical Support. Our team is ready to help.

 

 

Animal Component – Free (ACF)

 

Animal component-free products are manufactured and formulated using raw materials that are certified to not contain any animal, including human, derived products.

 

Final products and production process are, at no point, exposed or contaminated with animal-derived products or ancillary by-products.

Chemically Defined (CD)

 

Chemically defined products and formulations contain only known chemically pure components and substances.

 

Product or formulation may contain protein of recombinant origin that was expressed in a well-characterized and controlled expression system.

 

Final product contains, or used in its manufacturing processes, raw materials that have a known chemical structure and concentration (e.g. small molecules, salts, carbohydrates, amino acids, fatty acids, steroids, etc.).

Xeno – Free (XF)

 

Product or formulation contains human serum-derived components, but no components from animals other than humans.

 

---

 

Serum – Free (SF)

 

Product or formulation does not contain human AB serum or fetal bovine serum (FBS), but may contain biological materials derived from serum proteins, such as albumins or immunoglobulins. However, protein materials are purified as to maintain lot-to-lot consistency.

Carrier – Free

 

BSA or other equivalent carrier-proteins. are typically added for protein stability and to increase shelf life. However, addition of carrier-proteins may produce nonrelated or undesired effects on experiments. Our RUO and GMP recombinant proteins are carrier-free, thus eliminating this risk.
