Tech Info / Data

Background: 

The addition of a carrier to cytokine solutions can increase the stability and shelf-life of the protein. Human Serum Albumin (HSA) expressed in engineered human cells has low endotoxin levels and is animal-component-free. Human cell-expressed (HCE) HSA is ideal for use as a carrier protein.
