Genetic engineering methods

Advances in whole genome sequencing and genetic engineering methods are enhancing our ability to modify genomes in all species. 

The catchword interferon sufficiently supports this statement, there is no clairvoyance needed to predict the rapid application of genetic engineering methods to other as yet unexplored areas. 

As noted earlier, genetic engineering methods can be used not only to make a particular protein but also to introduce amino acid substitutions into the protein in a controlled fashion. These protein engineering methods can be used to modify proteins to facilitate their purification.

Advances in genetic engineering methods have enabled the generation of a variety of different antibody fragments and fusion proteins, and allowed the construction of molecules, the properties of which are tailored for the specific requirements of the intended therapeutic application [30]. These properties focus on efficacy -that is, the biological activity that addresses the mechanism of action. In addition, issues such as biochemical and biophysical stability, solubility, and production yield which influence the cost of goods (COG), and the pharmacokinetic properties as well as the immunogenicity of the protein, play an important role (see Table 1.1). 

Mutated proteins can be readily produced by using genetic engineering methods. It is possible to construct new genes for proteins, with designed properties, by deletion, insertion, transposition or substitution. The chemical procedures for doing this will not be described here. 

For a particular recombinant protein solution (produced by genetic engineering methods), the total concentration estimated by 280 nm absorbance measurements is 0.8 mg mL . However, biological activity measurements suggest that the concentration is only 0.6 mg mL. What are the possible reasons for this discrepancy ...

According to a Phillips spokesman, the joint venture will attempt to commercialize applications of recombinant DNA and other genetic engineering methods to enhance oil recovery and other processes used in oil and gas production, agriculture, manufacture of chemicals, and the company s other businesses. 

There are two techniques for polynucleotide synthesis that are applied for the production of medium- to large-sized DNA. PCR is commonly utilized for amplification or modification of medium-sized DNA motifs (150-10,000 base pairs). For larger DNA sequences (>10,000 base pairs), genetic engineering is preferred. Both require solid phase synthesis of DNA sequences primers for PCR or short DNA pieces for gene assembly in genetic engineering methods.
