Description
Accession
Q61559
Source
DNA sequence encoding Mouse FcRn including a C-His tag was expressed in HEK293 Cells.
Molecular weight
Recombinant Mouse FcRn is a protein consisting of amino acid residues [Ser22-Ser297(FCGRT) & Ile21-Met119(B2M)] ,The protein has a predicted MW of 32.1 kDa (FCGRT)&11.7 kDa (B2M). Due to glycosylation, the protein migrates to 50-55 kDa (FCGRT)&14-15 kDa (B2M) based on Tris-Bis PAGE result..
Purity
>95%, as determined by SDS-PAGE and HPLC
Biological Activity
see methods section
Endotoxin
Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).
Presentation
Recombinant Mouse FcRn was lyophilized from 0.2 µm filtered PBS solution pH7.4
Reconstitution
Centrifuge vial to ensure maximal product extraction, recommended:20sec, 5K RPM
Storage
The lyophilized protein is stable for at least 2 years from date of receipt at -20° C.
