serumderived

Serum-derived refers to biological materials or components obtained from serum, the liquid portion of blood that remains after clotting. Serum contains proteins, antibodies, growth factors, hormones, and various enzymes, and is used as a rich source of nutrients and signaling molecules in research, medicine, and consumer products. The term describes substances isolated or derived from serum, rather than produced synthetically or generated in cell culture.

Common serum sources include fetal bovine serum (FBS), human serum, and other animal or pooled donor sera. In research, serum-derived preparations include growth factors, antibodies, and extracellular vesicles isolated from serum. In cosmetics and dermatology, serums marketed as serum-derived may contain proteins and peptides sourced from human or animal serum. Handling and processing typically involve screening for pathogens, aliquoting, and storage under controlled conditions to preserve bioactivity.

Challenges and considerations associated with serum-derived materials include batch-to-batch variability, risk of pathogen transmission, and ethical or regulatory considerations depending on the species source and intended use. Many laboratories pursue serum-free or chemically defined alternatives to improve reproducibility and safety. Regulatory frameworks govern the use of serum-derived products, particularly for therapeutic applications and cosmetic claims. The term does not imply a single standard product; rather, it describes any component originally sourced from serum, with details depending on species origin, processing methods, and intended use.
