LAG3, also known as CD223, functions as a critical immune checkpoint receptor that plays a central role in regulating T cell activation and maintaining immune homeostasis. Expressed on activated T cells, natural killer cells, and regulatory T cells, LAG3 binds to MHC class II molecules and contributes to T cell exhaustion in chronic infections and the tumor microenvironment. This makes LAG3 a compelling target for immuno-oncology research and studies investigating immune regulation mechanisms.
This recombinant monoclonal antibody, clone 8F6, offers the reproducibility and consistency that demanding research applications require. Because recombinant antibodies are produced from defined sequences rather than hybridoma supernatants, researchers benefit from lot-to-lot uniformity that supports reliable longitudinal studies and reproducible experimental outcomes. The human IgG1 isotype format and affinity-chromatography purification ensure high purity suitable for sensitive detection methods.
Validation studies demonstrate robust performance across multiple platforms. In immunohistochemistry, this antibody successfully detects LAG3 in paraffin-embedded human testis tissue at dilutions ranging from 1:50 to 1:200, using citrate buffer antigen retrieval. Functional ELISA testing confirms strong binding activity to immobilized human LAG3 protein, with EC50 values in the low nanogram per milliliter range, indicating high-affinity target recognition.
The unconjugated format provides flexibility for researchers to pair this antibody with detection systems optimized for their specific workflows. Whether investigating checkpoint inhibitor mechanisms, characterizing tumor-infiltrating lymphocyte populations, or exploring LAG3 biology in immune regulation, this antibody delivers the specificity and validated performance essential for advancing immunology research.
