Rat Cathepsin B (CTSB) ELISA Kit

The Assay Genie rat-specific immunoassay quantifies Cathepsin B, a lysosomal cysteine protease implicated in extracellular matrix degradation, tumor cell invasion, and inflammatory tissue damage. Each microplate is configured for 96 assays, with precoated wells, detection reagents, and standards supplied so researchers can generate a standard curve and read unknown rat samples against kit controls. Reagents should be stored refrigerated until first use to preserve antibody and substrate activity.

Investigators in cardiac remodeling, neuroinflammation, hepatic injury, or tumor microenvironment studies rely on CTSB quantification to track enzyme release across experimental groups. The protocol involves adding sample and detection reagents in sequence, followed by a colorimetric readout. The kit is intended for research use only and supports preclinical rat model work where Cathepsin B activity correlates with disease progression and therapeutic response. The assay has been validated for samples commonly used in rat experimental workflows, including serum fractions, plasma fractions, and other liquid preparations from rat models.
