Related Product Information for SIRPA/CD172a active protein
Signal Regulatory Protein alpha (SIRPalpha) is a monomeric approximately 90 kD type I transmembrane glycoprotein. The 504 amino acid human SIRPalpha contains two Ig-like C1-type domains and one Ig-like V-type domain. SIRPalpha can express in various tissues, mainly on brain and myeloid cells, including macrophages, neutrophils, dendritic and Langerhans cells. It also can detect in neurons, smooth muscle and endothelial cells. SIRPA is an immunoglobulin-like cell surface receptor for CD47. SIRPalpha acts as docking protein and induces translocation of PTPN6, PTPN11 and other binding partners from the cytosol to the plasma membrane. SIRPalpha shows adhesion of cerebellar neurons, neurite outgrowth and glial cell attachment. SIRPalpha engagement generally produces a negative regulatory signal; it may mediate negative regulation of phagocytosis, mast cell activation and dendritic cell activation.

Product Notes
The SIRPA/CD172a sirpa (Catalog #AAA177937) is an Active Protein produced from Human Cells and is intended for research purposes only. The product is available for immediate purchase. The amino acid sequence is listed below: Glu31-Arg3 70. It is sometimes possible for the material contained within the vial of "Signal-Regulatory Protein alpha-1/SIRPA/CD172a) Biotinylated, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
