This study characterizes three monoclonal antibodies (mAbs) developed against the constant (C) region of the immunoglobulin light (IgL) sigma chain isotype of the channel catfish, Ictalurus punctatus. Microsphere bead assays and Western blot analyses utilizing different recombinant (r) proteins show that these anti-catfish IgL sigma chain mAbs each specifically recognize the denatured form of IgL sigma. Importantly, Western blotting of catfish sera using the anti-IgL sigma mAbs also identified an IgL chain-sized immunoreactive band(s) of approximately 27kDa. It is anticipated that these mAbs in combination with the already existing anti-catfish Ig heavy (H) and IgL chain mAbs will be useful in future studies examining the functional roles of the different catfish IgL isotypes.

D007127 Immunoglobulin Constant Regions The domains of the immunoglobulin molecules that are invariable in their amino acid sequence within any class or subclass of immunoglobulin. They confer biological as well as structural functions to immunoglobulins. One each on both the light chains and the heavy chains comprises the C-terminus half of the IMMUNOGLOBULIN FAB FRAGMENT and two or three of them make up the rest of the heavy chains (all of the IMMUNOGLOBULIN FC FRAGMENT) Ig Constant Regions,Immunoglobulin Constant Region,Constant Region, Ig,Constant Region, Immunoglobulin,Constant Regions, Ig,Constant Regions, Immunoglobulin,Regions, Ig Constant
D007132 Immunoglobulin Isotypes The classes of immunoglobulins found in any species of animal. In man there are nine classes that migrate in five different groups in electrophoresis; they each consist of two light and two heavy protein chains, and each group has distinguishing structural and functional properties.

D007147 Immunoglobulin Light Chains Polypeptide chains, consisting of 211 to 217 amino acid residues and having a molecular weight of approximately 22 kDa. There are two major types of light chains, kappa and lambda. Two Ig light chains and two Ig heavy chains (IMMUNOGLOBULIN HEAVY CHAINS) make one immunoglobulin molecule.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D000918 Antibody Specificity The property of antibodies which enables them to react with some ANTIGENIC DETERMINANTS and not with others. Specificity is dependent on chemical composition, physical forces, and molecular structure at the binding site. Antibody Specificities,Specificities, Antibody,Specificity, Antibody
