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 26.3 kDa.
*The DDM/CHS buffer (Cat. No. DC-11) is sold separately and not included in protein, you can follow the link for product information.
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.
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 HEPES, 150 mM NaCl, DDM, CHS, pH7.5 with glycerol as protectant.

Performance Data
Bioactivity-ELISA

Immobilized Human / Cynomolgus Claudin-18.2, His,Twin-Strep Tag (Cat. No. CL2-H5587) at 1 μg/mL (100 μL/well) can bind Monoclonal Anti-Chimeric Claudin-18.2 Antibody, Human IgG1 with a linear range of 0.1-2 ng/mL (QC tested).
Protocol
Immobilized Human / Cynomolgus Claudin-18.2, His,Twin-Strep Tag (Cat. No. CL2-H5587) and Human Claudin-18.1, His,Twin-Strep Tag at 5 μg/mL (100 μL/well) respectively, the Monoclonal Anti-Chimeric Claudin-18.2 Antibody, Human IgG1 can bind the Human / Cynomolgus Claudin-18.2, His,Twin-Strep Tag (Cat. No. CL2-H5587) with a linear range of 0.2-16 ng/mL, but can not bind the Human Claudin-18.1, His,Twin-Strep Tag (Routinely tested).
Protocol
