THY1, also known as CD90, is a glycosylphosphatidylinositol-anchored membrane glycoprotein that serves as a critical marker in immunological research. Originally identified as a thymocyte differentiation antigen, THY1 plays important roles in cell adhesion, signal transduction, and cell-cell interactions. Its expression patterns make it particularly valuable for identifying specific cell populations, including mesenchymal stem cells and certain fibroblast subsets, positioning it as an essential target for researchers investigating immune cell biology, stem cell characterization, and tissue microenvironment studies.
This recombinant monoclonal antibody, clone 15B3, offers the reproducibility and consistency that demanding experimental workflows require. Generated against a synthesized peptide derived from human THY1 protein, the antibody benefits from recombinant production technology, ensuring sequence-defined specificity and eliminating the lot-to-lot variability that can compromise longitudinal studies or multi-site collaborations. The rabbit IgG format provides excellent signal amplification potential while maintaining specificity for human samples.
Validation in immunohistochemistry demonstrates reliable performance in paraffin-embedded human kidney tissue, where the antibody successfully detected THY1 at dilutions ranging from 1:50 to 1:200. The validated protocol employed citrate buffer antigen retrieval under high pressure conditions, followed by overnight primary antibody incubation at 4°C and detection via HRP-conjugated goat anti-rabbit polymer system with DAB visualization. This established workflow provides researchers with a solid foundation for adapting the antibody to their specific tissue analysis needs. Additional compatibility with ELISA extends its utility for quantitative applications.
For investigators exploring immunology, stem cell biology, or tissue architecture, this THY1 antibody delivers the technical reliability needed to generate meaningful, reproducible data.
