Protein Production Services

grid_2023_proteinSBH Sciences has produced over 80 highly pure and active biologics, available without any tag or carrier protein.

Custom protein synthesis services are available, from gene cloning to purified, active product.

Each production lot of protein is assessed for endotoxin using the Limulus Amoebocyte Lysates (LAL) assay. Our standard endotoxin specification is < 0.5 EU/mg.

Our expertise in cell-based assays and biomarker analyses ensures that purity, activity, and lot-to-lot consistency are rigorously assessed.

A more detailed description of these services is available on our Cell Culture page.

Take advantage of our 25 years of experience in recombinant protein development and production. We have the knowledge and the capability to address your protein-production requirements.
