Experience APS

Animal Models

APS works with all large and small research animal species with the exception of non-human primates. We have a wealth of experiences and capabilities that are brought to bear in helping clients answer their research questions and aid with study design. We regularly perform complex animal surgeries and model creations for establishing physiological or mechanical models of disease states. We are also experienced in sample collections and analysis of endpoints for biomarkers of disease.

Genetic Disease Models

Ossabaw swine

APS has extensive experience with studies using Ossabaw swine, which is a sound model for assessing treatments for hypertension and metabolic syndrome. Ossabaw swine express a phenotype for a propensity to obesity. Consumption of a high caloric diet causes these animals to manifest obesity, insulin resistance, impaired glucose tolerance, dyslipidemia, and hypertension. Ossabaw swine are also prone to atherosclerotic disease.
