Product Description |
Recombinant Rat FcRn Protein is expressed from HEK293 with His tag at the C-terminus.It contains Ala23-Ser298 (FCGRT) and Ile21-Met119 (B2M). |
Product Background |
The neonatal Fc receptor (FCRN) is an approximately 45 kDa transmembrane glycoprotein with structural homology to MHC class I proteins. It is widely expressed in endothelial and epithelial cells and plays an important role in IgG homeostasis and antigen presentation by dendritic cells.FCGRT & B2M heterodimer protein (FcRn complex) consist of two subunits: p51, and p14 , and forms an MHC class I-like heterodimer. |

Amino Acid Range |
Ala23-Ser298(FCGRT) & Ile21-Met119(B2M) |
Molecular Weight |
The protein has a predicted MW of 32.60 kDa (FCGRT) and 11.63 kDa (B2M). Due to glycosylation, the protein migrates to 45-60 kDa (FCGRT) and 13-15 kDa (B2M) based on Bis-Tris PAGE result. |
Activity |
The affinity constant of 3.26 nM as determined in SPR assay (Biacore T200). See testing image for detail. |

C-His |
Expression System |
HEK293 |
Purity |
> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC |
Endotoxin |
Less than 1EU per ug by the LAL method. |
Form |
Lyophilized |
Shipping |
Shipped at ambient temperature. |
Formulation |
Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water. |
Stability And 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. |
