Not all proteins are created equal. Like people who prefer food that are organic, scientists in the research community prefer to use proteins that are made from human cells, not E.coli or insect.
Powered by our collection of TrueORF human cDNA clones, the scientists at OriGene have expressed over 10,000 full length human proteins and lysates from human cells (HEK293 cell).
The advantages of proteins made from human cells are the optimal preservation of protein structure and post-translational modifications, which presumably keep the function of the protein. These proteins are ideal for drug discovery, antibody production, positive controls, assay development, and protein to protein interaction study. You may learn more about our protein portfolio.
Share the Power of Protein with Fun and Prizes
'Protein' is derived from the Greek word meaning 'occupying first place.' The definition emphasizes the primary importance of protein to all living things.
