Reconstitution
It is not recommended to reconstitute to a concentration less than 100 μg/mL. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
Buffer
Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.2.
Conseil sur la manipulation
Always centrifuge tubes before opening. Do not mix by vortex or pipetting.

Stockage commentaire
Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.

Sujet
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 Alternative Names: Tyrosine-Protein Phosphatase Non-Receptor Type Substrate 1, SHP Substrate 1, SHPS-1, Brain Ig-Like Molecule with Tyrosine-Based Activation Motifs, Bit, CD172 Antigen-Like Family Member A, Inhibitory Feceptor SHPS-1, Macrophage Fusion Receptor, MyD-1 Antig
