Human TPBG/5T4 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human TPBG/5T4 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus
It contains Ser32-Ser355 [Accession | Q13641-1].

分子量大小(Molecular Weight)

The protein has a predicted MW of 38.2 kDa. Due to glycosylation, the protein migrates to 50-70 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 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)

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 TPBG on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.

SEC-HPLC

The purity of Human TPBG is greater than 95% as determined by SEC-HPLC.

ELISA Data

Immobilized Human TPBG, His Tag at 0.5 μg/ml (100 μl/Well) on the plate. Dose response curve for Anti-TPBG Antibody, hFc Tag with the EC50 of 7.3 ng/ml determined by ELISA.

背景(Background)

The oncofetal tumor-associated antigen 5T4 (TBGP) has been linked with CSC properties in several different malignancies. 5T4 has functional attributes that are relevant to the spread of tumors including through EMT, CXCR4/CXCL12, Wnt, and Hippo pathways which may all contribute through the mobilization of CSCs.

分子别名(Synonyms)

M6P1; 5T4AG; WAIF1; TPBG; 5T4

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