Abstract:
Antibodies raised against individual viral envelope proteins have been used in white spot syndrome virus (WSSV) neutralization assays. We report here the sequence analysis of cDNAs encoding the variable regions of a novel monoclonal antibody that binds to the viral envelope protein and neutralizes WSSV infection. The heavy and light variable chains are most homologous to VH7183 germline gene (AF120472) and IgVk RF germline gene (AJ235936), respectively. Database searches using the derived sequences predicted residues comprising CDR loops. The 12 amino acid residue of the heavy chain CDR3 is rich in negatively charged aspartic acid (25%) and did not show significant homology to any murine V gene available on the database. This study provides insights on the paratope-epitope interaction and can be used to identify compounds with comparable properties as the paratope leading to future development of drugs and vaccines for WSSV infection.

01:10Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

01:25Antibody Structure and Classes
The basic structure of an antibody consists of four protein chains: two identical heavy chains and two identical light chains. These chains are held together by disulfide bonds and other non-covalent interactions, forming a Y-shaped structure.
