Specificity: Ala24-Ser297(FCGRT)&Ile21-Met119(B2M)

Sterility: 0.22 μm filtered

Endotoxin Level: < 0.1 EU/μg of the protein by LAL method.

Biological Activity Comment: 1.Measured by its binding ability in a functional ELISA. Immobilized Human FCGRT&B2M at 5 μg/mL (100 μL/well) can bind biotinylated human IgG1 with a linear range of 1-6μg/mL.|2.Immobilized Trastuzumab on COOH Chip can bind Human FCGRT&B2M Heterodimer Protein with an affinity constant of 0.22 μM as determined in a SPR assay (OpenSPR).

Application Details

Restrictions: For Research Use only

Handling

Format: Lyophilized

Reconstitution: Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid votex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1 % BSA, 5 % HSA, 10 % FBS or 5 % Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.

Buffer: Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.

Storage: -20 °C,-80 °C

Storage Comment: Store the lyophilized protein at -20°C to -80 °C for long term.
After reconstitution, the protein solution is stable at -20 °C for 3 months, at 2-8 °C for up to 1 week.

Target Details

Target: FcRn (neonatal Fc Receptor (FcRn))

Alternative Name: FcRn

Background:

Description: FCGRT & B2M heterodimer protein (FcRn complex) consist of two subunits: p51 (equivalent to FCGRT), and p14 (equivalent to beta-2-microglobulin), and forms an MHC class I-like heterodimer. Fc fragment of IgG, receptor, transporter, alpha (FCGRT) binds to the Fc region of monomeric immunoglobulins gamma and mediates the uptake of IgG from milk. FCGRT possible role in transfer of immunoglobulin G from mother to fetus. Beta-2-microglobulin (B2M) is a component of MHC class I molecules, MHC class I molecules have α1, α2, and α3 proteins which are present on all nucleated cells (excludes red blood cells) and B2M involved in the presentation of peptide antigens to the immune system.
