Question

To make primary antibodies one must first inject host animals with the gene of interest. The animal reacts by making antibodies against the gene, and antibodies are then isolated from its blood. (True/False)

Answer 1

The statement is true. Primary antibodies are produced by injecting host animals with the gene of interest and collecting the antibodies from their blood.

Step-by-step explanation:

The statement is true. Primary antibodies are produced by injecting host animals with the gene of interest. When the animal is exposed to the gene, its immune system responds by producing antibodies against that specific gene. The antibodies are then isolated from the animal's blood and used for research, diagnostic purposes, or therapeutic applications.

For example, when researchers want to study a specific protein, they can inject the protein's gene into a rabbit. The rabbit's immune system will recognize the protein as foreign and produce antibodies against it. These antibodies can be collected from the rabbit's blood and used to detect or analyze the protein of interest.

This method of producing antibodies is called polyclonal antibody production because multiple antibodies are generated in response to different epitopes on the gene of interest. It is a common and effective technique used in the field of biology.
