Human IL-3 R alpha/CD123 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human IL-3 R alpha/CD123 Protein is expressed from HEK293 with His tag at the C-Terminus.
It contains Thr19-Arg305 [Accession | P26951-1].

分子量大小(Molecular Weight)

The protein has a predicted MW of 33.9 kDa. Due to glycosylation, the protein migrates to 60-70 kDa based on Bis-Tris PAGE result.

纯度(Purity)

> 95% as determined by Bis-Tris PAGE

内毒素(Endotoxin)

Less than 1EU per μg by the LAL method.

制剂(Formulation)

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

重构方法(Reconstitution)

Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

存储(Storage)

-20 to -80°C for 24 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.

产品数据(Assay Data)
Bis-Tris PAGE

Human IL-3 R alpha on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.

SEC-HPLC

The purity of Human IL-3 R alpha is greater than 95% as determined by SEC-HPLC.

ELISA Data

Immobilized Human IL-3 R alpha, His Tag at 1μg/ml (100μl/Well) on the plate. Dose response curve for Anti-IL-3 R alpha Antibody, hFc Tag with the EC50 of 7.7ng/ml determined by ELISA (QC Test).

SPR Data

Human IL-3, hFc Tag captured on CM5 Chip via Protein A can bind Human IL-3 R alpha, His Tag with an affinity constant of 0.276 μM as determined in SPR assay (Biacore T200).

背景(Background)

Interleukin-3 receptor subunit alpha, also known as IL-3 receptor subunit alpha, IL-3R-alpha, CD123, and IL3RA, is a single-pass type I membrane protein which belongs to the type I cytokine receptor family and Type 5 subfamily.The specific alpha subunit of the interleukin-3 receptor (IL-3Ralpha, CD123) is strongly expressed in various leukemic blasts and leukemic stem cells and seems to be an excellent target for the therapy of leukemias.

分子别名(Synonyms)

CD123; IL-3R subunit alpha; IL3R; IL3RA; IL-3Ra; IL3RAY; IL3RX; IL3RY; MGC34174; IL-3 R alpha

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