Pacific BioLabs has recently completed validation of an expanded panel of general clinical chemistry readouts using its Siemens Dimension® Xpand Plus Integrated Chemistry System. This fully automated system allows for the analysis of multiple clinical chemistry analytes from a single plasma source allowing investigational insight into a number of therapeutic categories. This expanded panel is suitable for studies involving in vivo rodent models used at Pacific BioLabs as well as Discovery and Preclinical studies in support of Client needs. As a long-standing component of Pacific BioLabs in vivo diagnostic capabilities in the Toxicology Department, the Siemens Dimension® Xpand Plus is ideal for rapid, same day results taking advantage of the latest technology to reduce sample prep time and costs. Pacific BioLabs personnel have extensive experience and knowledge ready to assist clients in supporting study designs taking advantage of this valuable pre-clinical diagnostic tool.
