1.
Glycoprotein produced by B lymphocytes and plasma cells in response to foreign substance exposure
2.
One of the polypeptide units that makes up and immunoglobulin molecule
3.
Small chain in an immunoglobulin molecule that is bound to the larger chain by disulfide bonds
4.
f 2 types of light chains present in ~2/3 of immunoglobulins
5.
f 2 types of light chains present in ~1/3 of immunoglobulins
6.
Amino-terminal region of an immunoglobulin that has a unique amino acid sequence and is responsible for the specificity of the antibody
7.
Carboxy-terminal segment of an antibody molecule that consists of a polypeptide sequence found in all chains of that type
8.
Flexible portion of the heavy chain of an immunoglobulin molecule that is located between the 1st and 2nd constant regions – allows the molecule to bend and antigen-binding sites to operate independently
9.
Glycoprotein that links immunoglobulin monomers together – only found in IgM and IgA
10.
Fragment Fragment of an immunoglobulin molecule obtained by papain cleavage that consists of a light chain and ½ of a heavy chain held together by disulfide bonding
11.
fragment of an immunoglobulin molecule obtained by papain cleavage that consists of the carboxy-terminal halves of 2 heavy chains that are held together by disulfide bonds
12.
Very specific antibody derived from a single antibody-producing cell that has been cloned or duplicated
