Application Details

Restrictions: For Research Use only

Handling

Format: Lyophilized

Reconstitution: Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 μg or less, at 1 mg/mL for 500 μg or 1 mg lyophilized powder. Do not mix by vortex or vigorous shaking.

Buffer: Lyophilized from 0.22 μm filtered solution in PBS ( pH 7.4). Normally 8 % trehalose is added as protectant before lyophilization.

Storage: -20 °C,-80 °C

Storage Comment: -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.

Expiry Date: 12 months

Target Details

Target: FcRn (neonatal Fc Receptor (FcRn))

Alternative Name: FcRn

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.

Molecular Weight: 31.5 kDa (FCGRT)&11.7 kDa (B2M). Due to glycosylation, the protein migrates to 35-40 kDa (FCGRT)&13-14 kDa (B2M) based on Bis-Tris PAGE result.

UniProt: P55899

Pathways: Regulation of Leukocyte Mediated Immunity, Positive Regulation of Immune Effector Process
