Abstract：
:White sturgeon (Acipenser transmontanus) immunoglobulin (Ig) was purified from serum by two methods, ion-exchange chromatography and gel filtration and precipitation of the euglobulin fraction. The purity of these immunoglobulin preparations was confirmed by gel electrophoresis. Sequence analysis of the N-terminal amino acids confirmed that the purified protein was immunoglobulin. The major portion of the immunoglobulin preparation consisted of two proteins with estimated molecular weights (m.w.) of 870 and 170 kDa. The m.w. of the H- and L-chains of the purified Ig were 73 and 27-30 kDa, respectively, as determined by SDS-PAGE. Ion-exchange purified Ig was used to immunize mice for the production of monoclonal antibodies. This resulted in the production of six stable hybrids that recognized sturgeon Ig, two specific for heavy chain and four specific for light chain. The two anti-H-chain mabs were highly specific for white sturgeon Ig while all four anti-L-chain mabs cross reacted with Ig from green sturgeon (A. medirostris), Atlantic sturgeon (A. oxyrhynchus oxyrhynchus), shovelnose sturgeon (Scaphirhynchus platorynchus), and paddlefish (Polyodon spathula), (all Chondrosteans), but not with channel catfish (Ictalurus punctatus), rainbow trout (Oncorhynchus mykiss) or striped bass (Morone saxatilis). The mabs were used to enumerate the percentage of sIg+ lymphocytes in the peripheral blood of white sturgeon by flow cytometry. The percentage of cells positively stained with the mabs ranged from 12 to 28%. In a comparison of mabs with polyclonal rabbit anti-sturgeon Ig serum by ELISA the mabs produced a larger signal and less background than the polyclonal serum.
