It is a T or Y-shaped monomer of 4 looping linked polypeptide chains
Each antibody varies in shape, but they are most often depicted as "Y" shaped
YES
antibody is just a protein. Every gene codes a protein. So an antibody protein is coded by codons (triplets of nucleotides) in the gene.
antibody
No, it is not. Antibody = A protein that fights infection.
Antibody
YES
Generally there are two antibodies used. Primary antibody which can bind specifically to the protein of interest. And a secondary antibody coupled with a detection system such as HRP that would bind the primary antibody and signals the presence of protein of interest.
Antibody - produced by B lymphocytes.
antibody
You are thinking of an antibody.
Antibody is a type of protein produced by the immune system, its function is to fight antigens (bacteri, virus)
Ann antibody is a complex protein molecule. Our immune system uses antibodies to fight bacteria.
Polyclonal antibody recognizes several epitopes on the target protein while monoclonal antibody recognizes only single epitope. Sometimes, monoclonal antibodies are not able to precipitate the antigen because the epitope might need to be exposed on the surface of the antigen to be recognized by the antibody. Since the epitope might be hidden and it's a single epitope that is recognized by the monoclonal antibody, the propability of the antibody to reconize the epitope is lower compared with the polyclonal antibody that recognizes several epitopes on the target protein.
