Recombinant Human FcRn & B2M H

Recombinant Human FcRn & B2M Heterodimer  (CI01)

 

产品说明(Description)

Recombinant Human IgG Fc fragment receptor transporter is produced by our Mammalian expression system and the target gene encoding Ala24-Leu290&Ile21-Met119 is expressed with a 6His tag at the C-terminus. 

Accession #: P55899&P61769

Known as: IgG receptor FcRn;Neonatal Fc receptor;FCRN

 

制剂（Formulation）

Lyophilized from a 0.2 μm filtered solution of 50mM HEPES,150mM Nacl,pH7.4.

 

质量控制（Quality Control） 

Purity:            Greater than 95% as determined by reducing SDS-PAGE.    

Endotoxin:    Less than 0.1 ng/ug (1 EU/ug) as determined by LAL test.

 

复溶（Reconstitution）

Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100 μg/ml.
Dissolve the lyophilized protein in distilled water.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.    

 

保存（Storage）

Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.
Reconstituted protein solution can be stored at 4-7°C for 2-7 days.
Aliquots of reconstituted samples are stable at < -20°C for 3 months.     

 

背景（Background）

FcRn complex consist of two subunits: IgG receptor FcRn  large subunit p51（alpha chain) and Beta-2-microglobulin（Beta chain). The complexes is similar in structure to MHC class I-like heterodimer. Beta-2-microglobulin involved in the presentation of peptide antigens to the immune system. FcRn binds to the Fc region of monomeric immunoglobulins gamma, mediates the uptake of IgG from milk,Possible role in transfer of immunoglobulin G from mother to fetus. A principal component of antibody transport is the neonatal receptor for the Fc portion of immunoglobulin, a heterodimer of a MHC-1 alpha-chain homolog ( FcRn ) and beta-2-microglobulin ( B2M ).
