Dr. J. Oriol Sunyer has developed a highly-specific monoclonal IgT antibody derived from the expression of CH2-4 domains of trout IgT heavy chain.  This is the only anti-IgT antibody on the market and can readily assess immune status in teleosts.

The identification and development of this antibody represents a major advance in understanding teleost immunity and has significant implications for the aquaculture market, which was estimated at $98.4B in 2008
