Rabbit heart tissue pieces and blocks are extensively used in cardiovascular research, comparative physiology, cardiac pathology, pharmacology, and translational biomedical research. The rabbit (Oryctolagus cuniculus) heart exhibits electrophysiological and excitation–contraction coupling properties that more closely resemble those of the human heart than commonly used murine models, particularly with respect to ventricular action potential duration, calcium handling, and repolarization mechanisms. Consequently, rabbit cardiac tissue is widely employed to investigate myocardial structure, ischemia–reperfusion injury, cardiac remodeling, arrhythmogenesis, heart failure, fibrosis, vascular biology, myocardial repair, and regenerative medicine strategies. These biospecimens are also valuable for histopathology, molecular profiling, biomarker discovery, and preclinical evaluation of cardiovascular therapeutics.

Key Features

• Native Cardiac Tissue Architecture : Suitable for cardiovascular research and histopathological analysis.

• Preserved Cardiac Organization : Maintains atrial, ventricular, myocardial, endocardial, and epicardial tissue organization when appropriately preserved.

• Broad Analytical Compatibility : Compatible with histology, immunohistochemistry (IHC), immunofluorescence (IF), nucleic acid extraction, transcriptomics, proteomics, and spatial molecular profiling, depending on specimen preservation.

• Supports Cardiovascular Research : Frequently used for studies of myocardial ischemia, cardiac fibrosis, electrophysiology, calcium signaling, ventricular remodeling, and arrhythmia mechanisms.

• Translational Research Resource: Applicable to comparative cardiovascular biology, cardiac safety pharmacology, toxicologic pathology, and translational cardiovascular research.
