Source

Detergent Biotinylated Human STEAP1 Full Length Protein, Avitag,Flag&His Tag (ST1-H82D3) is expressed from human 293 cells (HEK293). It contains AA Glu 2 - Leu 339 (Accession # Q9UHE8-1).

Predicted N-terminus: Asp

Molecular Characterization

This protein carries a Flag tag at the N-terminus, and a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™). The protein has a calculated MW of 44.7 kDa. The protein migrates as 40-43 kDa and 65-70 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

*The Buffer A (Cat. No. DN-12) is sold separately and not included in protein. You can learn about the product information through the link. We recommend DN-12 for ELISA assay and DC-11 for SPR/BLI assay.

Structure

Each full-length transmembrane protein is encapsulated by detergent micelle.

Synthesis Process

Through mild detergent micelle extraction, dedicated solubilization, and stringent affinity purification, we maximally retain the native transmembrane conformation of full-length transmembrane proteins throughout downstream purification. This workflow yields purified, detergent-solubilized proteins free of unrelated membrane impurities and exogenous scaffold proteins, with exceptional purity, accurate quantitation, and well-preserved biological activity—ideal for immunization, binding assays in antibody discovery and screening (ELISA) and affinity testing (SPR and BLI), etc.

Labeling

Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

Protein Ratio

Passed as determined by the SABA assay / HABA assay / binding ELISA.

Purity

>85% as determined by SDS-PAGE.

Formulation

This product is not suitable for cell based experiments due to cytotoxicity of detergent.
Detergent buffer is INDISPENSABLE to keep membrane protein soluble and active, under no circumstances should you remove detergent.
Detergent buffer is sold separately and not included in protein, and please contact us if you need the buffer.
If glycerol is not compatible with your application, remove glycerol just before the immediate experiment, and NEVER store glycerol-free protein solution.

Supplied as 0.2 μm filtered solution in 50 mM HEPES, 150 mM NaCl, Buffer A, pH7.5 with glycerol as protectant.

Please avoid repeated freeze-thaw cycles.

This product is stable after storage at:
  • The product MUST be stored at -70°C or lower upon receipt;
  • -70°C for 3 months under sterile conditions.

Background

A transmembrane metalloreductase highly overexpressed in prostate cancer with minimal normal tissue distribution. It facilitates cellular iron and copper reduction. Its tumor-selective profile makes it a compelling target for antibody-drug conjugates and T-cell engagers in metastatic prostate cancer.
