Source

Detergent Human Claudin-4 Protein, His,Twin-Strep Tag (CL4-H5587) is expressed from Baculovirus-Insect cells. It contains AA Met 1 - Val 209 (Accession # O14493-1).

Predicted N-terminus: Met

Molecular Characterization

Other Tags and Version Biotin & Other Labeled Version

This protein carries a polyhistidine tag at the N-terminus and a twin strep tag at the C-terminus.

The protein has a calculated MW of 27.5 kDa. The protein migrates as 25-27 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE).

*The DDM/CHS buffer (Cat. No. DC-11) is sold separately and not included in protein, you can follow the link for product information.

1. Structure

   

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

2. 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.

Endotoxin

Less than 1.0 EU per μg by the LAL method / rFC method.

Purity

>90% as determined by SDS-PAGE.

Formulation

This product is not suitable for cell based experiments due to cytotoxicity of DDM.
DDM and CHS are INDISPENSABLE to keep membrane protein soluble and active, under no circumstances should you remove DDM and CHS.
DDM/CHS buffer (DC-11) 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 Tris, 150 mM NaCl, DDM, CHS, pH7.5 with glycerol as protectant.
