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 protein migrates as 20 kDa and 40 kDa under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
>80% as determined by SDS-PAGE.
Supplied as 0.2 μm filtered solution in 50 mM HEPES, 150 mM NaCl, DDM, CHS, pH7.5 with glycerol as protectant.
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 circumastance 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 to your application, remove glycerol just before immediate experiment, and NEVER store glycerol-free protein solution.
Contact us for customized product form or formulation.
Please avoid repeated freeze-thaw cycles.
