Human Cathepsin L (CTSL) ELISA Kit

Cathepsin L is a lysosomal cysteine protease with broad physiological roles spanning intracellular protein turnover, antigen processing, bone remodeling, and extracellular matrix proteolysis. This quantitative immunoassay from Assay Genie enables researchers to quantify Cathepsin L (CTSL) concentrations in human specimens, supporting translational studies of cancer metastasis, cardiovascular remodeling, atherosclerosis, and inflammatory disease where this enzyme's dysregulation has been implicated. The microplate-based kit supports 96 individual determinations per run, streamlining medium-throughput biomarker discovery workflows. Built for in vitro research use only and standardized against recombinant human CTSL, the reagents detect both pro- and mature enzyme isoforms and accommodate downstream work with tissue homogenates and cell lysate preparations. Refrigerated storage of all reagents is recommended prior to first use, and the kit is delivered ready to run with pre-coated plates, calibrated standards, buffers, and detection components included.
