Proteins and Peptides

Proteins and peptides are key research tools for life scientists. Cell Sciences offers an extensive range of over 7,000 proteins and peptides. Our portfolio includes recombinant proteins produced in mammalian, insect and bacterial cell expression systems. We also offer animal-free versions of recombinant proteins and native proteins purified from tissues and fluids from multiple species. A range of bioactive synthetic peptides, hormones and blocking peptides are also available. Our catalog of proteins and peptides are high purity reagents with validated bioactivity and low endotoxicity. They assist with the study of chemokines, cytokines, growth factors and their associated receptors, adaptive and innate immunity, and the complement and coagulation cascades. Highlights of our broad range of recombinant human proteins include our top selling human soluble VEGFR1/FLT1 and human FGF-21.
