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
Request for sequence蛋白结构（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.
标记（Labeling）
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
蛋白标记度（Biotinylation）
As determined by Quantitative ELISA binding assay against streptavidin.
纯度（Purity）
>90% as determined by SDS-PAGE.
制剂（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.
