In medicine a heterologous transplant means 'between species' or 'from one species to another'.
In structural biology a heterologous association is a binding mode between the protomers of a protein structure. In a heterologous association, each protomer contributes a different set of residues to the binding interface. In contrast, two protomers form an isologous association when they contribute the same set of residues to the protomer-protomer interface.
, are chosen usually because they are easy to transfer DNA into or because they allow for a simpler assessment of the protein's function. heterologous expression systems. The choice of recipient cell type is often based on an experimental need to examine the protein's function in detail, and the most prevalent recipients, known as transduction and transfection). Methods for transferring foreign genetic material into a recipient cell include expression vector) is added to the recipient cell. The genetic material that is transferred typically must be within a format that encourages the recipient cell to express the cDNA as a protein (i.e., it is put in an cDNA genetic material coding for the protein (the complementary DNA or
