Belongs to The category of natural compounds referred to as monohydroxy bile acids, alcohols and derivatives. They're bile acids, alcohols or any in their derivatives bearing a hydroxyl group.
One program commonly useful for protein expression in eukaryotic cells is infection of insect cells by baculovirus vectors, which direct pretty higher levels of expression of genes inserted in place of a viral structural protein. Alternatively, substantial amounts of protein expression is usually achieved using acceptable vectors in mammalian cells. Expression of cloned genes in yeast is particularly valuable simply because straightforward methods of yeast genetics could be employed to detect proteins that connect with other cloned proteins or with precise DNA sequences.
