Active Protein

Active Protein

Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. An active protein is one that does what it is supposed to. Its opposite is an inactive protein which does not work. The transition may be caused by things such as acidity and heat which destroys or deactivates the protein. CUSABIO's active protein primarily includes cytokines, enzyme, hormone, et al. All of our products have been sold with high-quality and good biological activities. The purity of most active proteins are higher than 97%, and all of which have been validated activity and low endotoxin, stored in freeze-dried powder form for best stability, majority tag-free thus closer to native protein.
