Polyclonal antibodies --> derived from different B cell lines. They are a mixture of immunoglobulin molecules secreted against a specific antigen, each recognizing a different epitope
Monoclonal antibodies (mAb or moAb) are monospecific antibodies that are identical because they are produced by one type of immune cell that are all clones of a single parent cell. Given almost any substance, it is possible to create monoclonal antibodies that specifically bind to that substance; they can then serve to detect or purify that substance.

PAbs are heterogeneous and recognize a
host of antigenic epitopes, the effect of change on a single
or small number of epitopes is less likely to be significant.
PAbs are also more stable over a broad pH and salt concentration,
PAbs frequently have better specificity than MAbs because
they are produced by a large number of B cell clones
each generating antibodies to a specific epitope, and polyclonal
sera are a composite of antibodies with unique specificities.
mono activation requires the close proximity
of Fc receptors. Modification of antibodies by covalently
linking a fluorochrome or radionuclide may also alter antibody
binding. This potential is less of a concern when using
PAbs, which recognize a host of epitopes, but it can be
significant for MAbs if the change affects its monospecific
binding site.
elisa-->The capture and primary antibodies
must be different isotypes, if not from different species, so
that the secondary antibody will only detect the presence of
the primary antibody and correctly indicate that the antigen
has been captured in the well.

IGFBP secreted by muscle cells may play an important
autocrine/paracrine role in muscle growth and development.
prostatic kallikreins (prostate-specific antigen) hK2 and hK3 may influence specifically the tumoral growth of prostate cells through the degradation of IGFBPs, to increase IGF bioavailability.
