Human Alkaline Phosphatase (Placental type)/ALPP Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human Alkaline Phosphatase (Placental type)/ALPP Protein is expressed from HEK293 with His tag at the C-Terminus.
It contains Ile23-Asp506 [Accession | P05187].

分子量大小(Molecular Weight)

The protein has a predicted MW of 53.8 kDa. Due to glycosylation, the protein migrates to 63-68 kDa 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 ug 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)

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 12 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
2-8°C for 2-7 days 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 Alkaline Phosphatase (Placental type) on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.

SEC-HPLC

The purity of Human Alkaline Phosphatase (Placental type) is greater than 95% as determined by SEC-HPLC.

ELISA Data

Immobilized Human Alkaline Phosphatase (Placental type), His Tag at 1μg/ml (100 μl/Well) on the plate. Dose response curve for Anti-Alkaline Phosphatase Antibody, hFc Tag with the EC50 of 2.8ng/ml determined by ELISA (QC Test).

背景(Background)

Alkaline phosphatase can be considered "our favorite enzyme" for reasons apparent to those who diagnose and treat metabolic bone diseases or who study skeletal biology. Few might know, however, that alkaline phosphatase likely represents the most frequently assayed enzyme in all of medicine. Elevated activity in the circulation is universally recognized as a marker for skeletal or hepatobiliary disease.

分子别名(Synonyms)

Alkaline phosphatase; PLAP-1; ALPP; PLAP

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