Mechanical Loading Rig

A mechanical loading rig is a laboratory apparatus that applies controlled physical forces to biological samples, enabling researchers to study how cells, tissues, and engineered constructs respond to mechanical stress. The system typically delivers defined loads through compression, tension, shear, or cyclic movement while researchers regulate variables such as force, displacement, duration, and frequency. In biology, mechanical loading rigs support mechanobiology studies of bone, cartilage, muscle, and connective tissue, where physical cues influence cell behavior, tissue remodeling, and function. These platforms also help evaluate biomaterials and tissue-engineered constructs, linking controlled mechanical conditions to biological outcomes and informing regenerative medicine and disease research.

Innate defenses to virus infections are triggered by pattern recognition receptors (PRRs). The two cytoplasmic PRRs RIG-I and PKR bind to viral signature RNAs, change conformation, oligomerize, and activate antiviral signaling. Methods are described which allow to conveniently monitor the conformational switching and the oligomerization of these cytoplasmic PRRs.
