ENTPD1, also known as CD39, serves as a critical ectonucleotidase that hydrolyzes extracellular ATP and ADP to AMP, functioning as a key regulator of purinergic signaling in the immune system. This enzyme plays a pivotal role in modulating inflammatory responses and has emerged as an important marker in immunology research, particularly in studies examining regulatory T cell function, tumor microenvironment immunosuppression, and vascular biology. The balance between extracellular ATP as a danger signal and its degradation products profoundly influences immune cell behavior, making ENTPD1 a compelling target for researchers investigating immune regulation mechanisms.
This recombinant monoclonal antibody, clone 5D3, offers the reproducibility and consistency that demanding experimental workflows require. Produced using recombinant technology with a defined sequence, this antibody eliminates the lot-to-lot variability that can compromise longitudinal studies and multi-site collaborations. The human IgG1 isotype format, generated against recombinant human ENTPD1 protein, provides researchers with a reliable tool for detecting this target in human samples.
Validation through immunohistochemistry demonstrates effective performance in paraffin-embedded human placenta tissue at dilutions ranging from 1:50 to 1:200. Testing on a Leica Bond system with citrate buffer antigen retrieval at pH 6.0 and overnight primary antibody incubation at 4°C yielded clear staining patterns, providing researchers with an optimized starting protocol for their own tissue studies. The antibody is also validated for ELISA applications, offering flexibility across different experimental platforms.
For immunology researchers investigating purinergic signaling, immune checkpoint biology, or tissue-specific ENTPD1 expression patterns, this antibody delivers the specificity and consistency needed for meaningful experimental outcomes.
