"why are monoclonal antibodies specific? Use knowledge of protein struct to explain y Watch
So what is your question or what do you want help with?
As for the specific protein structure, it involves variable regions, and immunoglobin folds and more detail than I am willing to type out. Do your own research
Antigen-antibody interaction is like a lock-and-key mechanism.
Each antibody will have its own 3-D shape.
Which will only fit one antigen.
Monoclonal = a sample containing one type of antibody, so it will bind to only one antigen.
Polyclonal = a mix of antibodies, they usually bind to dissimilar, but related antigens.
Monoclonal antibodies are more expensive than polyclonal antibodies because they need to be purified first.
antibodies are proteins so they have a specific primary structure therefore they will have a specific tertiary structure.
So only antigens that are complemenary will bind so the monoclonal antibody is specific
hope this helps
