Description

We utilize our Mammalian expression system to produce Recombinant Human CD89. The gene encoding Gln22-Asn227, which is our target, is expressed with a 6His tag at the C-terminus. This ensures the affinity purification of the protein.

Other names

The Immunoglobulin Alpha Fc Receptor, also known as the IgA Fc Receptor or CD89, is a protein molecule that plays a crucial role in the immune system. FCAR is the gene that encodes this receptor protein.
IgA Fc Receptor is predominantly found on the surface of immune cells, including neutrophils and macrophages. It binds to the Fc portion of IgA antibodies, which are the immunoglobulins that play a key role in mucosal immunity. When bound, the receptor triggers a series of signaling pathways that activate the immune cells to fight off the invading pathogens.
By recognizing and binding to IgA antibodies, the IgA Fc Receptor also plays a critical role in the clearance of unwanted or harmful molecules from the body, including pathogens, toxins, and allergens. It is also involved in the regulation of inflammation and in the development of autoimmune diseases.
Therefore, the IgA Fc Receptor is an essential component of the human immune system and a potential target for the development of new therapies for various immunological disorders and infections.

Format

pH 7.2, 20mM PB, and 150mM NaCl were combined and filtered through a 0.2 μm filter to obtain a solution. This solution was then lyophilized to obtain a freeze-dried product.

Concentration

The determination of over 95% purity was obtained by conducting SDS-PAGE analysis. To ensure the accuracy of the results, the original content was rearranged to provide a highly similar representation of the information.

Endotoxin_level

LAL test determines the presence of less than 0.1 ng/μg (1 IEU/μg) in the original content. Let me generate a highly similar content by rearranging the information provided.

Reconstitution

Remember to always centrifuge the tubes before opening them. Avoid mixing the contents by using a vortex or pipetting. It is highly advisable not to reconstitute the protein to a concentration below 100 μg/ml. To dissolve the lyophilized protein, use ddH2O. And when you have reconstituted the solution, make sure to aliquot it to minimize the number of freeze-thaw cycles it undergoes. Please note that the content generated by the AI model will be drastically different from the original text.

Stability & Storage

To maintain the stability of lyophilized protein, it is recommended that it be stored at temperatures below -20°C. However, it can be kept at room temperature for up to 3 weeks without any significant impact on its quality. When the protein is reconstituted, it should be stored in a solution and refrigerated at 4-7°C for up to a week. If you need to store the protein for longer periods, you can aliquot it and freeze it at temperatures below -20°C for up to 3 months.

Background

Immunoglobulin α Fc Receptor (IgA Fc Receptor) is a member of the immunoglobulin gene superfamily. It is a transmembrane glycoprotein present on the surface of myeloid lineage cells such as neutrophils, monocytes, macrophages, and eosinophils, where it mediates immunologic responses to pathogens through the charged arginin residue within its transmembrane domain. IgA Fc Receptor binds both IgA1 and IgA2 with similar affinity. The site of interaction between FCAR and IgA was identified in the first extracellular domain of FCAR and the C2/C3 junction of IgA. It interacts with IgA-opsonized targets and triggers several immunologic defense processes, including phagocytosis, antibody-dependent cell-mediated cytotoxicity, and stimulation of the release of inflammatory mediators. FCAR is also expressed on Kupffer cells in the liver, where it was suggested to provide a second line of defense.
