Complement Technology, Inc. was formed to continue supplying the medical research community with the highest quality reagents for complement research. CompTech has purchased the entire complement business from Advanced Research Technologies, Inc. of San Diego, California. CompTech and ART have established a formal ongoing relationship to guarantee a smooth transition. The owners and operators of CompTech have a combined experience of 65 years in the complement field. We plan to continue to be the lowest cost supplier of the highest quality reagents available. We will expand the line of reagents to meet the changing needs of research. We would welcome suggestions on how best to do this.

CompTech will begin accepting orders July 1, 2005. All catalog numbers and product specifications will remain the same as those of Advanced Research Technologies.
