| Note | Validity: The validity for this kit is at least 6 months. Up to 12 months validity can be provided on request. This product is for research use only. The range and sensitivity is subject to change. Please contact us for the latest product information. For accurate results, sample concentrations must be diluted to mid-range of the kit. If you require a specific range, please contact us in advance or write your request in your order comments. Please note that our ELISA and CLIA kits are optimised for detection of native samples, rather than recombinant proteins. We are unable to guarantee detection of recombinant proteins, as they may have different sequences or tertiary structures to the native protein. |
Descripción
Signal regulatory protein alpha (SIRPA) is a transmembrane glycoprotein encoded by the SIRPA gene in humans, primarily expressed on myeloid cells such as macrophages, dendritic cells, and neutrophils, and to a lesser extent on neurons. SIRPA belongs to the immunoglobulin superfamily (IgSF) and functions as an inhibitory receptor, playing a critical role in immune homeostasis, cellular signaling, and cell-cell interactions. SIRPA interacts primarily with CD47, a widely expressed protein known as the “don’t eat me” signal on host cells. This interaction is fundamental for immune surveillance, as it prevents macrophages and other immune cells from targeting healthy self-cells for phagocytosis, thereby maintaining tolerance to self while supporting immune responses against foreign antigens and damaged cells. SIRPA is integral in modulating immune responses and is implicated in a range of physiological processes, including cell migration, cell adhesion, and tissue homeostasis. Research indicates that SIRPA is not only crucial in the innate immune system but also impacts adaptive immunity. Dysregulation or mutations of SIRPA have been linked to autoimmunity, cancer, and other pathologies due to its role in immune evasion, particularly in the context of cancer, where many tumor cells upregulate CD47 to escape immune clearance.
