Proteins have the most diverse and dynamic role among all macromolecules in the body, providing intracellular and extracellular scaffold support, forming receptors and channels in membranes, catalyzing biochemical reactions, and transporting molecules within the cell.
Protein therapeutics have several advantages over small molecule drugs. First, proteins usually have highly specific and complex functions that cannot be mimicked by simple chemical compounds. Second, there is often less potential for protein therapeutics to interfere with normal biological processes and cause adverse reactions, as the action of proteins is highly specific. Third, since the body naturally produces many proteins that are used as therapeutics, these agents are generally well tolerated and are unlikely to elicit immune responses. Fourth, for diseases caused by gene mutations or deletions, protein therapeutics can provide effective alternative treatments without the need for gene therapy.
At Creative Bioarray, we understand that getting access to the right protein is a major obstacle to successful downstream research applications in the drug discovery process. Over the past 10 years, we have continuously invested and expanded our expert team, technology platform, capabilities and service scope to one of the most advanced research protein service team in the drug discovery industry. Our scientists, with extensive experience in molecular biology, protein expression, protein purification and structural/physicochemical characterization, will advance your project to match your exact needs from gene synthesis to fully characterized purified proteins using state-of-the-art instrumentation. With their wide technical expertise, our scientists can solve various protein expression and purification challenges.
