FITC-Labeled CD7 His Tag Protein is a recombinant detection tool consisting of the extracellular domain of the T-cell surface marker CD7 fused with a histidine tag and covalently labeled with fluorescein isothiocyanate (FITC). As a specific probe for a key marker of T lymphocyte and NK cell activation, it holds irreplaceable value in the diagnosis and classification of T-cell acute lymphoblastic leukemia, certain autoimmune diseases, immunodeficiency disorders (such as HIV infection), and the development of cutting-edge cell therapies.

FITC-Labeled CEACAM-5/CD66e Fc Chimera is a recombinant protein tool consisting of the extracellular domain of human carcinoembryonic antigen-related cell adhesion molecule 5 (CEACAM-5/CD66e) fused to the Fc fragment of immunoglobulin G (IgG) and labeled with fluorescein isothiocyanate (FITC).

FITC-Labeled CD38 Fc Chimera is a recombinant protein tool that combines the extracellular domain of human CD38 with the Fc fragment of immunoglobulin G (IgG) and is labeled with fluorescein isothiocyanate (FITC). As a specific detection probe for the multifunctional immunomodulatory receptor CD38, it is non-pathogenic but serves as a core experimental reagent in key disease research areas such as multiple myeloma, autoimmune diseases, metabolic disorders, viral infections, and age-related immune decline.
