Polyclonal antibodies
Monoclonal antibodies
Inexpensive to produce
Expensive to produce
Technology required is low
High technology required
Skills required are low
Training is required for the technology use
Time scale is short
Time scale is long for hybridomas
Produces large amounts of non specific antibodies
Can produce large amounts of specific antibodies but may be too specific
Recognizes multiple epitopes on any one antigen
Recognizes only one epitope on an antigen
Can be batch to batch variability
Once a hybridoma is made it is a constant and renewable source and all batches will be identical
Antibody molecules are held together by disulfide bonds, which are covalent bonds formed between sulfur atoms in the amino acid cysteine. These bonds help maintain the structure and stability of the antibody molecule.
In coomassie staining, a dye binds to all proteins, visualizing all of them. In this way, it's nonspecific. The dye diffuses into the the original gel. In a western, an antibody binds specifically to one or more proteins, making it specific for proteins to which the antibody can bind. In order for the antibody to access the proteins from the original gel, they are moved (blotted) to the surface of a membrane (usually nitrocellulose).
Difference between collenchyma and chlorenchyma
Potential difference
what is the difference between pf soluble and insoluble
polyclonal antobody is the antibody produced for many or non specific antigens but antiserum is the antibody for a specific antigen
Monoclonal antibodies are highly specific, targeting a single antigen, while polyclonal antibodies can target multiple antigens. Monoclonal antibodies are produced from a single clone of cells, resulting in uniformity, while polyclonal antibodies are produced from multiple clones of cells, leading to variability.
Polyclonal antibodies are produced by multiple B cells and are a mix of antibodies that target different epitopes on an antigen, resulting in broader specificity. Monoclonal antibodies are produced by a single B cell clone and target a single epitope on an antigen, leading to higher specificity. Polyclonal antibodies are typically produced by immunizing animals, while monoclonal antibodies are generated through hybridoma technology or recombinant DNA technology.
Chickenpox and shingles result from the same virus, and generate the same antibodies. There is no difference between chickenpox antibody and shingles antibody, and there is only one test (varicella virus antibody) for both.
Antibodies lack a transmembrane domain.

Antigen binding site or epitope is a part of an antigen that is recognized by the antibody. Paratope is a part of an antibody that binds on epitope.
Opsonization involves an antibody binding to a pathogen itself while neutralizing invovles an antibody binding to a toxin, AKA something the pathogen produces.
the autoimmune reaction is the reaction between the antibody and antigene when both come from the same body but the isoimmune reaction is between the antigene and antibody produced for the same antigene ( the same according to the type but not the immunity )
difference between an antibody and an antigen
Antibodies are secreted (plasma cells), while immunoglobulins are membrane-bound (naive B cells).
In the context of antibody structure, heavy chains are larger and provide structural support, while light chains are smaller and help with antigen binding.
