產品描述：

The SIRPA antibody is generated by immunizing rabbits with the peptide mapping within amino acids 31-373of the human SIRPA protein. It is a polyclonal antibody and occurs as a Biotin-conjugated IgG. This Biotin-conjugated SIRPA antibody can be used as a detection antibody in combination with HRP to amplify the signal for the measurement of the SIRPA protein in the ELISA analysis. Its purity is over 95% using protein G purified. It only reacts with human SIRPA. The target protein SIRPA is a membrane glycoprotein immunoreceptor rich in cells of monocyte lineage. SIRPA-CD47 ligation initiates a signaling cascade that leads to the suppression of phagocytosis.

靶點詳情

功能：

Immunoglobulin-like cell surface receptor for CD47. Acts as docking protein and induces translocation of PTPN6, PTPN11 and other binding partners from the cytosol to the plasma membrane. Supports adhesion of cerebellar neurons, neurite outgrowth and glial cell attachment. May play a key role in intracellular signaling during synaptogenesis and in synaptic function. Involved in the negative regulation of receptor tyrosine kinase-coupled cellular responses induced by cell adhesion, growth factors or insulin. Mediates negative regulation of phagocytosis, mast cell activation and dendritic cell activation. CD47 binding prevents maturation of immature dendritic cells and inhibits cytokine production by mature dendritic cells.
