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

ICOS (E5F7E) Rabbit mAb (SignalStar^® Conjugate 0188) recognizes endogenous levels of total mouse ICOS protein.

Species Reactivity:

Mouse

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Val198 of mouse ICOS protein.

Background

ICOS (Inducible Co-Stimulator, CD278) is a member of the CD28 family that regulates T cell activity and immune responses (1). The ICOS protein contains an extracellular IgV-like domain, a transmembrane domain, and an intracellular domain with a YMFM motif (1-2). ICOS is primarily expressed on activated CD4⁺ and CD8⁺ T cells (1). Upon binding to its ligand, ICOS potentiates the T cell response to antigen through activation of the PI3K signaling pathway (3). In addition to enhancing T cell activation and proliferation, ICOS plays an important role in the regulation of T follicular helper cells (4). Research studies suggest that ICOS is a potential therapeutic target, and could serve as a prognostic biomarker for neoplastic therapy involving CTLA-4 blockade (5-7).
