For producing a recombinant protein (for therapeutic purpose) in large scale, which vector would you choose
High-copy-number, because higher the copy number of vector plasmid, higher the copy number of gene and consequently, the protein coded by the gene is produced in high amount.

Define the terms Antigen and Antibody. Name any two diagnostic kits based upon them.
An antigen is a foreign substance that elicits the formation of an antibody. Antibody is a protein that is synthesised in response to an antigen. Antigen and antibody show high degree of specificity in binding each...

ELISA technique is based on the principles of antigen and antibody interaction.
Yes. One can use antibody against the enzyme (that is responsible for the metabolism of phenylalanine) to develop ELISA based diagnostic technique. The patient where the enzyme protein is absent...

What would happen when you grow a recombinant in a bioreactor but forget to add antibiotic to the medium in which the recombinant is growing.
In the absence of antibiotic, there will be no pressure on recombinants to retain the plasmid (containing the gene of your interest). Since, maintaining a high copy number of plasmids...

What is the difference between native protein and denatured protein ?
Proteins found in a biological system with unique 3D-structure and biological activity is called native protein. When native protein is subjected to physical and chemical change, protein loses its biological activity...
