Product Overview

Tag	His
Host Species	Human
Synonym	CD47 Molecule, Antigenic Surface Determinant Protein OA3, CD47 Antigen (Rh-Related Antigen, Integrin-Associated Signal Transducer), Antigen Identified By Monoclonal Antibody 1D8, Integrin Associated Protein, Integrin-Associated Protein, Rh-Related Antigen, CD47 Glycoprotein, MER6, IAP, Integrin-Associated Signal Transducer, Leukocyte Surface Antigen CD47, CD47 Antigen, Protein MER6, OA3, CD47.
Background	CD47, functions in cell adhesions by performing as an adhesion receptorfor THBS1 on platelets, furthermore CD47 plays a role in the modulation ofintegrins. In addition, CD47 takes a vital part in memory formation as well assynaptic plasticity in the hippocampus. Receptor for SIRPA avoids maturation ofimmature dendritic cells and inhibits cytokine production by mature dendriticcells. CD47 prevents premature elimination of red blood cells, and it is also implicatedin membrane permeability changes induced following virus infection.
Description	CD47 expressed in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain (19-141 a.a.) and fused to a 6 a.a. His Tag at C-terminus containing a total of 129a.a. and having a molecular weight of 14.7kDa.CD47 shows multiple bands between 18-28kDa on SDS-PAGE, reducing conditions and purified by unique purification methods.

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.
