What portion of a secondary antibody bind to on a primary antibody?
antibodies are made up of two major pats. The Fc chain is species specific and the variable chain is epitope specific. Primary binds to a specific epitope on a structure or protein. Secondary antibodies are produced against the Fc region and are only specific to an animal's Fc region. Secondary antibodies often contain a color metric or fluorescent signal that indicates the presence of the primary antibody. Variable chains from secondaries can bind to specific animal Fc chain epitopes. For example, for a researcher may use a primary rabbit antibody bound to horseradish peroxidase (rabbit anti-HRP), then the researcher will us secondary with a color metric or fluorescence tag such as a mouse antibody against rabbit (mouse anti-rabbit). This would mean that the variable region of mouse anti-body would bind to the Fc chain of the rabbit antibody.
What is carrying capacity?
Carrying capacity is the number of individual that can be sustained within a population due to the availability of space and nutrients for a population to grow. Factors limiting carrying capacity include availability of food and water, competition, and space just to name a few.
What is the only bone not articulated with another bone in the human body?
The hyoid bone does not articulate with any other bone of the body, making it truly unique.
