- SourceUnconjugated Human TPBG, His,Avitag (TPG-H52E5) is expressed from human 293 cells (HEK293). It contains AA Ser 32 - Ser 355 (Accession # Q13641-1).Predicted N-terminus: Ser 32Request for sequence
- Molecular Characterization
This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag.
The protein has a calculated MW of 39.0 kDa. The protein migrates as 50-66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
- ApplicationTPG-H52E5 is the unconjugated version of TPG-H82Eb (Biotinylated Human TPBG, His,Avitag). It can be utilized for assay development or customized biotinylation according to the experimental designs.
- EndotoxinLess than 1.0 EU per μg by the LAL method.
- Purity
>90% as determined by SDS-PAGE.
- Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Unconjugated Human TPBG, His,Avitag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.
- BackgroundTrophoblast glycoprotein (TPBG), also known as 5T4, is the therapeutic target of several anticancer agents currently in clinical development, largely due to its high expression in tumors and low expression in normal adult tissues.This gene encodes a leucine-rich transmembrane glycoprotein that may be involved in cell adhesion. TPBG is expressed by all types of trophoblasts as early as 9 weeks of development.
