Mouse CTLA-4 PharmaGenie ELISA Kit (SBRS1323)

Mouse CTLA-4 (Cytotoxic T-Lymphocyte-Associated Protein 4) is a key immune checkpoint receptor that downregulates T-cell activation by outcompeting CD28 for binding to CD80 and CD86 on antigen-presenting cells, and this 96-assay immunoassay from Assay Genie provides quantitative measurement of the protein in murine samples. Quantification of CTLA-4 is widely relevant in tumor immunology, autoimmune disease models, and transplantation tolerance research, where altered receptor expression serves as a biomarker of T-cell anergy and regulatory T-cell function.

Validated for cell culture supernatants, plasma samples, and serum samples, the kit supports flexible workflows across in vitro and ex vivo experiments. Each kit contains a complete reagent set sufficient for one full microplate run, with a standard incubation-and-wash protocol producing an absorbance-based readout on standard plate readers. The assay is calibrated against recombinant mouse CTLA-4 standards and is intended for research use only; it is not cleared for diagnostic procedures.
