BP005324: Human Siglec-2/CD22 Protein with the C-His Tag
Source: The recombinant Human Siglec-2/CD22 Protein, (amino acids Asp20-Arg687) fused with a His tag at the C-terminus, was produced in HEK 293 cells.
Molecular Weight:The recombinant Human Siglec-2/CD22 protein with the His tag at the C-terminus has a predicted MW of 76.2 kDa. Due to glycosylation, the protein migrates to 100-120 kDa based on Tris-Bis PAGE result.
Activity: Immobilized recombinant Human Siglec-2 protein with the C-His tag at 1 ug/ml (100 ul/well) on the plate. Dose response curve for the recombinant Anti-Siglec-2 Antibody protein with the C-hFc tag with the EC50 of 6.6 ng/ml determined by ELISA.
Purity: >95% by SEC-HPLC and SDS-PAGE under reducing conditions.
Endotoxin Level: Less than 1 EU per ug of protein as determined by LAL method.
Formulation: Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution: It is recommended to reconstitute the lyophilized recombinant Human Siglec-2/CD22 Protein in sterile H2O to a protein concentration not less than 100 ug/ml. Centrifuge the tube before opening.
BP005325: Human Siglec-2/CD22 Protein with the C-hFc Tag
Source: The recombinant Human Siglec-2/CD22 Protein, (amino acids Asp20-Arg687) fused with a hFc tag at the C-terminus, was produced in HEK 293 cells.
Molecular Weight:The recombinant Human Siglec-2/CD22 protein with the hFc tag at the C-terminus has a predicted MW of 101.9 kDa. Due to glycosylation, the protein migrates to 120-130 kDa based on Tris-Bis PAGE result.
Activity: Immobilized recombinant Human Siglec-2 protein with the C-hFc tag at 0.5 ug/ml (100 ul/well) on the plate. Dose response curve for the recombinant Biotinylated Anti-Siglec-2 Antibody protein with the C-hFc tag with the EC50 of 18.4 ng/ml determined by ELISA.
Purity: >95% by SEC-HPLC and SDS-PAGE under reducing conditions.
Endotoxin Level: Less than 1 EU per ug of protein as determined by LAL method.
Formulation: Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution: It is recommended to reconstitute the lyophilized recombinant Human Siglec-2/CD22 Protein in sterile H2O to a protein concentration not less than 100 ug/ml. Centrifuge the tube before opening.
