Recombinant Mouse Signal-Regulatory Protein alpha-1/SIRPA/CD172a (C-Fc)

Cat.No.: CP68

Recombinant Mouse SIRPA (C-Fc)
Description
Recombinant Mouse Signal-Regulatory Protein alpha 1 is produced by our Mammalian expression system and the target gene encoding Lys32-Asn373 is expressed with a Fc tag at the C-terminus.
Accession #:Q6P6I8
Known as:Tyrosine-Protein Phosphatase Non-Receptor Type Substrate 1; CD172 Antigen-Like Family Member A;Signal-Regulatory Protein Alpha-1; CD172a; SIRPA; MFR; SHPS1; SIRP
Formulation
Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.
Quality Control
Purity:Greater than 95% as determined by reducing SDS-PAGE.
Endotoxin:Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.
Reconstitution
Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
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.
Storage
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.
Background
Mouse Signal Regulatory Protein α (SIRPα) is a type I transmembrane glycoprotein.It contains two Ig-like C1-type domains and one Ig-like V-type domain. Mouse SIRP alpha ECD shares 61%, 75%, 62%, 61%, and 59% aa sequence identity with human, rat, equine, bovine, and porcine SIRP alpha, respectively.SIRPα 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. SIRPα acts as docking protein and induces translocation of PTPN6, PTPN11 and other binding partners from the cytosol to the plasma membrane. SIRPα shows adhesion of cerebellar neurons, neurite outgrowth and glial cell attachment. SIRPα engagement generally produces a negative regulatory signal; it may mediate negative regulation of phagocytosis, mast cell activation and dendritic cell activation
