Synonym
FcRn alpha chain; FCGRT; FCRN; FCGRT&B2M
Source / expression
Recombinant Biotinylated Human FcRn Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Ala24-Ser297(FCGRT)&Ile21-Met119(B2M) [Accession | P55899(FCGRT)&P61769((B2M)].
Molecular weight
The protein has a predicted MW of 46.5 kDa. Due to glycosylation, the protein migrates to 48-55 kDa based on Bis-Tris PAGE result.
Endotoxin
Less than 1 EU per μg by the LAL method.
Purity
> 95% as determined by Bis-Tris PAGE
> 95% as determined by HPLC
Formulation
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution
Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.
Storage
-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
