    Product Description

    SignalStar multiplex immunohistochemistry (IHC) is an advanced technology for labeling multiple proteins simultaneously in tissue samples using specific primary antibodies and fluorescent detection reagents. This technology offers accuracy and reliability in visualizing and analyzing protein expression while maintaining spatial context and tissue architecture.

    SignalStar Oligo-Antibody Pairs are compatible with the SignalStar Multiplex IHC Buffer Kits for use in fluorescent multiplex imaging experiments. This product includes the oligo-conjugated antibodies and complementary oligos required for labeling your target protein on up to 10 slides. SignalStar Multiplex IHC Buffer Kits are required to amplify and image the target signal. Multiple oligo-antibody pairs can be conveniently combined into a multiplex panel using the SignalStar Multiplex IHC Panel Builder. SignalStar Multiplex IHC Kits & Reagents are not compatible with all of Cell Signaling Technology® products and protocols that are recommended for use in immunohistochemical assays.

    Protocol

    Specificity / Sensitivity

    TACSTD2/TROP2 (F4W4J) Rabbit mAb (SignalStar™ Conjugate 0150) recognizes endogenous levels of total TACSTD2/TROP2 protein.

    Species Reactivity:

    Human

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the extracellular domain of human TACSTD2/TROP2 protein. The antigen has been further characterized as corresponding to residues surrounding Ile219 of human TACSTD2/TROP2 protein.

    Background

    TROP2 is a transmembrane glycoprotein encoded by gene TACSTD2 (tumor-associated calcium signal transducer 2). TROP2 was first discovered as a biomarker of invasive trophoblast cells and later reported in many types of cancer cells, in various organs during development, and adult stem cells during homeostasis (1,2). TROP2 has an extracellular domain with EGF thyroglobulin type-1 repeats, a transmembrane domain, and a short cytoplasmic tail with a HIKE domain containing a PIP2 binding site and PKC phosphorylation site (Ser303) (1-4). TROP2 functions by regulating multiple signaling pathways, including the interaction of its extracellular domain with integrin beta1 to regulate FAK signaling, the association of its transmembrane domain with Claudin-1 and Claudin-7 for tight junction formation, and the regulation of intracellular calcium release by its PIP2 binding and activation of the ERK/MAPK pathway (1,2,5-8). All these functions are important for its role in tumor proliferation, metastasis, and invasion (1,2). PKC can phosphorylate TROP2 at Ser303; the phosphorylation changes the cytoplasmic tail conformation and further promotes its signaling (9). TROP2 can be activated through intramembrane proteolysis first by TACE, followed by further cleavage by Presenilin 1 and Presenilin 2. The proteolysis process is required for its role in tumor cell proliferation (10,11).
