Detailed explanation-1: -antiserum, blood serum that contains specific antibodies against an antigen (foreign agent), such as an infective organism or poisonous substance. Antibodies in antiserum work by detecting and subsequently neutralizing antigens.

Detailed explanation-2: -Antiserum is a blood serum containing monoclonal or polyclonal antibodies that is used to spread passive immunity to many diseases via blood donation (plasmapheresis).

Detailed explanation-3: -The antiserum detects two major components whose retention times on reversed-phase HPLC correspond to neuropeptide K(1–24) peptide and neuropeptide K together with several uncharacterized minor components.

Detailed explanation-4: -Complete answer:-Antiserum consists of either monoclonal or polyclonal antibodies that provide passive immunity.

Detailed explanation-5: -Because one antibody only recognizes a specific antigen, antibodies that attack cancer cells, for example, do not attack normal cells. This is called the “specificity” of an antibody toward that antigen.
