CEACAM1 Protein, Human, Recombinant (ECD, His & hFc Tag)
纯度:> 90 % as determined by SDS-PAGE
内毒素:< 1.0 EU per μg of the protein as determined by the LAL method
生物活性:Measured by its binding ability in a functional ELISA. Immobilized CEACAM8-His (Cat:11729-H08H) at 10 μg/mL (100 μL/well) can bind CEACAM1-Fch (Cat:10822-H03H), the EC50 of CEACAM1-Fch (Cat:10822-H03H) is 70-200 ng/mL.
蛋白构建:A DNA sequence encoding the extracellular domain of human CEACAM1 (NP_001020083.1) (Met 1-Gly 428) was fused with the C-terminal polyhistidine-tagged Fc region of human IgG1 at the C-terminus.
NP No.:NP_001020083.1
表达宿主:HEK293 Cells
种属:Human
预测 N 端:Gln 35
分子量:The secreted recombinant human CEACAM1/Fc chimera is a disulfide-linked homodimer. The reduced monomer comprises 642 amino acids and predicts a molecular mass of 71.4 kDa. As a result of glycosylation, the apparent molecular mass of rhCEACAM1 is approximately 124.8 kDa in SDS-PAGE under reducing conditions.
缓冲液:Lyophilized from sterile 100 mM Glycine, 500 mM NaCl, 5 % Glycerol, 50 mM Arg Hcl, 50 mM Glu, 0.01 % tween 20, pH 5.0.
Please contact us for any concerns or special requirements.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the hard copy of CoA.
运输方式:In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
稳定性 & 储存条件:Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃
Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
复溶:A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
