Product Specific Information
This monoclonal antibody Cr24.1 reacts with human CD355, also known as Class-I MHC-restricted T-cell-associated molecule (CRTAM). CD355 usually exists as a homodimer, however, it forms a heterodimer with its ligand Necl-2. CD355 is transiently expressed by activated NK, NKT, gamma delta T, and CD8+ T cells. CD355 is also expressed by Purkinje neurons. Human CD355 is involved in immunosurveillance of cancer cells, gamma delta T cell survival, cell polarity, retention of lymphocytes in lymph nodes, promotion of cytotoxicity in NK cells, and IFN gamma secretion from CD8+ T cells. Cr24.1 has been reported to have antagonist activity.
This Cr24.1 antibody has been pre-titrated and tested by flow cytometric analysis of stimulated normal human peripheral blood cells. This can be used at 5 µL (1 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test.
Light sensitivity: This tandem dye is sensitive to photo-induced oxidation. Please protect this vial and stained samples from light.
Fixation: Samples can be stored in IC Fixation Buffer (Proudct # 00-8222-49) (100 µL of cell sample + 100 µL of IC Fixation Buffer) or 1-step Fix/Lyse Solution (Product # 00-5333-54) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically.
Filtration: 0.2 µm post-manufacturing filtered.
Target Information
Class-I MHC-restricted T cell-associated molecule (CRTAM) is a gene located on chromosome 11q24.2, encoding a member of the immunoglobulin superfamily that plays a crucial role in immune cell interactions. CRTAM is expressed on activated CD8+ T cells, natural killer (NK) cells, and some subsets of CD4+ T cells, where it is involved in promoting cell adhesion, cytokine production, and cytotoxic responses. The protein binds to Necl-2 (CD112), mediating intercellular communication that influences immune responses, particularly in the context of viral infections and tumor surveillance. CRTAM's involvement in directing immune cell activity highlights its importance in the regulation of adaptive and innate immunity. Research into CRTAM is exploring its potential as a therapeutic target for modulating immune functions, aiming to enhance immune responses against cancer and infectious diseases or to attenuate autoimmune reactions.
