Storage	1. Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. 2. Avoid repeated freeze-thaw cycles. 3. Store working aliquots at 4°C for up to one week. 4. In general, protein in liquid form is stable for up to 6 months at -20°C/-80°C. Protein in lyophilized powder form is stable for up to 12 months at -20°C/-80°C.
Notes	Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Details

Target Function	Receptor (or element of a larger receptor complex) for C1q, mannose-binding lectin (MBL2) and pulmonary surfactant protein A (SPA). May mediate the enhancement of phagocytosis in monocytes and macrophages upon interaction with soluble defense collagens. May play a role in intercellular adhesion. Marker for early multipotent hematopoietic precursor cells. May play a role in cell-cell interactions during hematopoietic and vascular development.
Subcellular Location	Membrane; Single-pass type I membrane protein.
Database References	KEGG: mmu:17064 STRING: 10090.ENSMUSP00000096876 UniGene: PMID: 29498549 The expression of cd93 was observed in pancreatic islets, and leaky vessels were apparent in cd93-deficient pancreases. We further demonstrated that stress-induced release of sCD93 is impaired by hyperglycemia. Study propose CD93 as an important component in glucometabolic regulation. PMID: 27659228 soluble EGF-like domain containing CD93 protein is a novel angiogenic factor acting on the endothelium PMID: 23272129 [review] CD93 regulates inflammation as demonstrated in a murine model of cerebral ischemia reperfusion-induced injury and peritonitis; recent data suggests that a soluble form of CD93 regulates the inflammatory function of monocytes/ macrophages. PMID: 22206251 these data suggest that cell-associated CD93 regulates leukocyte recruitment and complement activation during murine peritonitis. PMID: 21849679 we speculate that CD93-neuroprotection is mediated via suppression of the neuroinflammatory response through downregulation of CCL21. PMID: 20439917 Cd93 may be an autoimmune susceptibility gene residing within the Idd13 locus, which plays a role in regulating absolute numbers of CD4(+) NKT cells. PMID: 20387063 Data demonstrate that inflammation triggers release of sCD93 in vivo, identify the inflammatory macrophage as a source of sCD93, and provide insight into the mechanism by which CD93 contributes to engulfment of apoptotic cells. PMID: 19603257 Impaired uptake of apoptotic cells in C1qRp-deficient mice indicates that the C1qRp receptor may contribute to the removal of dying cells in vivo. PMID: 15004139 CD93-deficient mice were unable to maintain antibody secretion and bone-marrow plasma-cell numbers, demonstrating that CD93 is important for the maintenance of plasma cells in bone marrow niches. PMID: 19228948 These data suggest that AA4.1 is a cell surface marker that can identify the earliest lymphohematopoietic progenitors in mouse development. PMID: 19458045

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
