Cellastim is a recombinant human serum albumin (HSA) that has been produced from an animal-free expression system.

• Replaces and outperforms FBS
• Well defined and consistent
• Animal-free, regulatory friendly
• Tested applications: ELISA
• Solubility (25 °C): cell culture tested
• Biological origin: expressed in rice

Cellastim has identical amino acid sequence and similar biophysical characteristics to the major HSA isoform found in human serum. Albumin is a cell culture supplement that functions as a carrier protein for fatty acids, growth factors, and trace minerals. Albumin also protects cells from damage due to toxins and by physical shear. Albumin is a common ingredient in many classical and custom media formulations. Albumin is used to reduce or eliminate serum and to support cell growth, health, and productivity.
