Human Transferrin R/CD71 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human Transferrin R/CD71 Protein is expressed from HEK293 with His tag at the N-terminus.
It contains Cys89-Phe760 [Accession | P02786].

分子量大小(Molecular Weight)

The protein has a predicted MW of 77.25 kDa. Due to glycosylation, the protein migrates to 78-90 kDa based on Bis-Tris PAGE result.

纯度(Purity)

> 90% as determined by Bis-Tris PAGE
> 95% as determined by HPLC

内毒素(Endotoxin)

Less than 0.1 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 transferrin receptor (CD71) is known as a receptor for IgA1 on mesangial cells. The transcript and protein expression of glomerular CD71 was determined by real-time polymerase chain reaction and immunohistochemistry. Human mesangial cells (HMCs) were treated with sera from IgAN patients and expression levels of CD71 and inflammatory cytokine markers were compared according to disease status.

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