Human cell expressed
•Over 90% recombinant proteins are human cell-expressed. Human cell expression ensures the proper folding, glycosylation, gamma-carboxylation and other post-translational modification of recombinant proteins.
•The majority of our recombinant proteins have been purified to purity >95%, suitable for most in vitro experiments.
•Some recombinant proteins have been purified to purity over 99%.
•The SDS-PAGE images of recombinant proteins are provided.
Low Endotoxin Level
•Human cell-expression ensures lower endotoxin level of most recombinant proteins.
•All recombinant proteins have been assessed for endotoxin using the Limulus Amoebocyte Lysates (LAL) assay, and most of the results are lower
1.0 EU / μg.
•The endotoxin level of TGF-beta 1 (CATALOG #: 10804-HNAH) is 0.15 EU / mg protein, and bFGF (CATALOG #: 10014-HNAE) is < 1.0 EU per 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.
•Dramatic cost saving for quality recombinant proteins.
•Special promotion for featured products.
•All proteins are manufactured in bulk quantities.
•Big discount for bulk order.

With multiple advanced technology platforms and large scale capacities, Sino Biological has quickly emerging as a leader life science research tool developer worldwide. All our proteins are manufactured in bulk quantities using sequence verified vectors and state-of-the-art mammalian, insect, or E. coli expression processes. We are adding more than 800 proteins per year, of which “hot” proteins are high on the priority list, such as H1N1 antigens and antibodies that we offered.
