TACSTD2, commonly known as Trop-2, is a transmembrane glycoprotein that has emerged as one of the most compelling targets in oncology research. This tumor-associated calcium signal transducer is overexpressed across a remarkable spectrum of epithelial cancers, including pancreatic, breast, colorectal, and lung carcinomas, where it drives proliferation, invasion, and metastatic progression. Its restricted expression in normal tissues combined with high tumor prevalence has made Trop-2 a prime focus for antibody-drug conjugate development and targeted therapeutic strategies.
This recombinant monoclonal antibody, clone 21E11, offers researchers the reproducibility essential for longitudinal studies and multi-site collaborations. Because the antibody sequence is defined and production occurs in controlled recombinant systems, you can expect consistent performance across lots, eliminating the variability that can confound experimental comparisons over time. The mouse IgG2a isotype and affinity-chromatography purification ensure high specificity for your human TACSTD2 detection needs.
Validation in flow cytometry demonstrates clear utility for cell surface expression analysis. Testing on BxPC-3 cells, a human pancreatic adenocarcinoma line known for robust Trop-2 expression, shows distinct positive staining with excellent separation from isotype control, confirming specific target recognition. Working dilutions between 1:50 and 1:200 provide flexibility to optimize signal intensity for your specific experimental conditions and instrumentation. The antibody is also validated for ELISA applications, supporting quantitative detection workflows.
For researchers investigating Trop-2 biology in cancer progression, therapeutic target validation, or biomarker development, this antibody delivers the technical consistency and validated performance needed to advance your studies with confidence.
