Biotinylated Rat FcRn Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Biotinylated Rat FcRn Protein is expressed from HEK293 with His tag and Avi Tag at the C-terminus of FCGRT.
It contains Ala23-Ser298(FCGRT) and Ile21-Met119(B2M) [Accession | P13599(FCGRT)&P07151(B2M)].

分子量大小(Molecular Weight)

The protein has a predicted MW of 33.9 kDa (FCGRT) and 11.63 kDa (B2M). Due to glycosylation, the protein migrates to 45-60 kDa (FCGRT) and 12-14 kDa (B2M) based on Bis-Tris PAGE result.

纯度(Purity)

> 95% as determined by Bis-Tris PAGE
> 95% as determined by HPLC

内毒素(Endotoxin)

Less than 1 EU per μg by the LAL method.

制剂(Formulation)

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

重构方法(Reconstitution)

Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.

存储(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.

背景(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.

分子别名(Synonyms)

FcRn alpha chain; FCGRT; FCRN; FCGRT&B2M

Note: HPLC results always come from liquid protein, due to absorption peak interference of trehalose in lyophilized powder.
