Application of Biotechnologies in Drug Discovery and Development

In this section we will focus primarily on recombinant proteins. We will discuss strategies specific to monoclonal antibody production in the introduction to antibodies and derivatives (Chapter 10). Issues specific to peptides will be discussed in the

What remains relatively unchanged, however, is how one uses the information available in the literature or other sources to identify the drug candidate that will have an optimal effect on the therapeutic target. The strategy to clone and express disease-related genes also remains unchanged. 

Basic understanding of DNA replication paves the way to isolate and manipulate genes of interest. 

Elucidation of molecular processes involved in transcription and translation [6,7] leads to the development of a bacterial and mammalian protein expression system to mass-produce proteins.

Liquid chromatography is an essential analytical tool for the separation of proteins in biotechnology and pharmaceutical product development. Applications are found throughout the development process of biological products, from drug discovery to quality control. Molecular properties of proteins, like molecular mass, net charge, hydrophobicity, and structure give ample opportunities to use HPLC for their separation.
