Human Cytotoxic T-Lymphocyte Associated Antigen 4 (CTLA4) ELISA Kit

CTLA-4 is an immune checkpoint receptor expressed on activated T cells and regulatory T cells, and quantifying its soluble form supports research in cancer immunology, autoimmune disease, and transplant rejection studies. This in vitro ELISA kit from Assay Genie is configured as a microplate-based immunoassay for the quantitative measurement of human CTLA-4 in cell lysates, tissue homogenates, and related experimental specimens. The assay is calibrated specifically for human samples and is supplied as a 96-assay kit intended for research use only. Researchers working on regulatory T cell biology, immune checkpoint blockade studies, or biomarker discovery will find the kit useful for tracking CTLA-4 levels across experimental conditions. Reagents arrive in a single-use microplate format, pre-configured for laboratory workflows measuring cytokine and immune receptor dynamics.
