Human Cathepsin Z (CTSZ) ELISA Kit

Cathepsin Z (CTSZ) is a lysosomal cysteine protease implicated in antigen presentation, cell migration, and tumor micro-environment remodeling, making it a target of interest in immunology and oncology research. This Assay Genie kit quantitatively measures human CTSZ protein across clinical specimens including tissue homogenates, supporting studies of protease activity in disease models. Capture antibodies are human-specific, with no significant cross-reactivity observed against rat or mouse cathepsin orthologs, enabling clean interpretation when comparing patient samples with animal model controls. The microplate format provides sufficient throughput for screening cohorts of clinical samples, while the kit components should be refrigerated at 4 °C upon arrival, with the reconstituted standards used immediately. Researchers investigating CTSZ expression in cancer progression, inflammatory disease, or protease pathway studies will find this kit a reliable complement to gene expression and immunohistochemistry workflows.
