Endotoxin Level • Human cell-expression ensures lower endotoxin level of most recombinant proteins. • Recombinant proteins were assessed for endotoxin using the Limulus Amoebocyte Lysates (LAL) assay, and the endotoxin levels are lower than 1.0 EU / μg. • The endotoxin level of TGF-beta 1 (CATALOG #:10804-HNAH) is 0.15 EU / mg protein as determined by the LAL method. Formulation and Stability • All recombinant proteins are carrier-free. The addition of a carrier protein (such as BSA) to protein solutions may disturb your experiments. • Most recombinant proteins are lyophilized from a sterile filtered solution containing protective agent: trehalose and mannitol. Trehalose is effective for stabilizing protein when lyophilized and during storage in solid state, and also for maximizing recovery upon reconstitution. Mannitol effectively prevents aggregation of protein. Affordable Price • Dramatic cost saving for quality recombinant proteins.
