An Automated Low-Cost Swim Tunnel for Measuring Swimming Performance in Fish

The study of swimming behavior is an important part of fish biology research and the swim tunnel is used to study swimming performance as well as metabolism of fish. In this investigation, we have developed a user-friendly, automated, modular, and low-cost swim tunnel that permits to study the perfo... More

A Rabbit Femoral Condyle Defect Model for Assessment of Osteochondral Tissue Regeneration

Osteochondral tissue repair represents a common clinical need, with multiple approaches in tissue engineering and regenerative medicine being investigated for the repair of defects of articular cartilage and subchondral bone. A full thickness rabbit femoral condyle defect is a clinically relevant mo... More

Cartilage Assessment Requires a Surface Characterization Protocol: Roughness, Friction, and Function

The surface of articular cartilage is integral to smooth, low-friction joint articulation. However, the majority of cartilage literature rarely includes measurements of surface characteristics and function. This may, in part, be due to a shortage of or unfamiliarity with fast, nondestructive, and, p... More

Optimized Protocol for Accurate Titration of Adeno-Associated Virus Vectors

Adeno-associated virus (AAV) is currently the most popular gene delivery vector for in vivo gene therapy. However, variability in titration methods between different laboratories affects the reproducibility of experiments and evaluation of safety and efficacy in clinical trials. We describe an optim...

Single-Use Capture Purification of Adeno-Associated Viral Gene Transfer Vectors by Membrane-Based Steric Exclusion Chromatography

We present membrane-based steric exclusion chromatography (SXC) as a universal capture step for purification of adeno-associated virus (AAV) gene transfer vectors independent of their serotype and surface characteristics. SXC is performed by mixing an unpurified cell culture supernatant containing A... More
