蛋白长度：A DNA sequence encoding the human SIRPA (NP_542970.1, with natural variant Gly 75 Ala) extracellular domain (Met1-Arg370) was expressed fused with a polyhistidine tag at the C-terminus.
性质：
表达系统：HEK293 Cells
种属：Human
氨基酸序：Met1-Arg370, Gly 75 Ala
标签类型：C-His
分子量：The recombinant human SIRPA consists of 351 amino acids and predictes a molecular mass of 39 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of human SIRPA is approximately 45-55 kDa due to glycosylation.
活性：Immobilized Recombinant Human CD47 Protein (ECD,Fc Tag)(Cat:PH51441M4) at 2 μg/mL (100 μL/well) can bind Recombinant Human SIRP alpha / CD172a Protein (ECD, His Tag)(Cat:PH50493M2), the ECis 280-850 ng/mL.
内毒素：< 1.0 EU per μg of the protein as determined by the LAL method.
基因名称：signal-regulatory protein alpha
通用名：SIRPA
蛋白序参考：NP_542970.1
总结：Tyrosine-protein phosphatase non-receptor type substrate 1, also known as SHP substrate 1, Inhibitory receptor SHPS-1, Brain Ig-like molecule with tyrosine-based activation motifs, Macrophage fusion receptor, CD172 antigen-like family member A, SIRPA and CD172a, is a single-pass type I membrane protein which contains two Ig-like C1-type (immunoglobulin-like) domains and one Ig-like V-type (immunoglobulin-like) domain. SIRPA is ubiquitously expressed. It is highly expressed in brain and detected at lower levels in heart, placenta, lung, testis, ovary, colon, liver, small intestine, prostate, spleen, kidney, skeletal muscle and pancreas. It is also detected on myeloid cells, but not T-cells. SIRPA is an immunoglobulin-like cell surface receptor for CD47. SIRPA acts as docking protein and induces translocation of PTPN6, PTPN11 and other binding partners from the cytosol to the plasma membrane. SIRPA supports adhesion of cerebellar neurons, neurite outgrowth and glial cell attachment. It may play a key role in intracellular signaling during synaptogenesis and in synaptic function. SIRPA is involved in the negative regulation of receptor tyrosine kinase-coupled cellular responses induced by cell adhesion, growth factors or insulin. It mediates negative regulation of phagocytosis, mast cell activation and dendritic cell activation.
形式：Lyophilized
纯度：> 98 % as determined by SDS-PAGE.
储存条件：In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
储存溶液：Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.
