Synthetic Low Density Lipoprotein for Animal Component Free Tissue Culture

main content


The recent explosion in molecular biology has led to increased demand for tissue culture media. Usually this media is supplemented with foetal calf serum which provides essential lipids to maintain cell viability and promote growth. Serum, however, is expensive and suffers from inherent biological variability, potential contamination from adventitious agents and increased regulatory scrutiny. This has led to the drive for animal component-free media but until now there has been no real animal-free lipid supplement available.



Groundbreaking research from the University of Strathclyde has produced a synthetic low density lipoprotein (sLDL) which can be prepared from animal-free ingredients and provides all the required lipids in one product. sLDL circumvents the problems associated with serum, and its constituents can be more accurately controlled. Unlike current artificial lipid supplements, sLDL also provides the cells with lipids in the correct biological format for natural assimilation via the LDL pathway.


Key Benefits

  • Prepared from certified animal free materials
  • Controlled lipid profile & concentration
  • Biomimetic
  • Capable of cGMP production
  • Chemically and physically stable (4°C)
  • Filterable (0.2 µm)
  • Surfactant, cyclodextrin and protein free


Markets and Applications

sLDL has applications in tissue culture and engineering, cellular therapy, and in vitro cell research.
