蛋白结构（Molecular Characterization）
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 40.4 kDa. The protein migrates as 55-67 kDa under reducing (R) condition, and 100-130 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
纯度（Purity）
>95% as determined by SDS-PAGE.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.

电泳（SDS-PAGE）
Rat CD47, Fc Tag on SDS-PAGE under reducing (R) and non-reducing (NR) conditions. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95% (With Star Ribbon Pre-stained Protein Marker).
活性（Bioactivity）-ELISA
Immobilized Mouse SIRP alpha, Mouse IgG2a Fc Tag (Cat. No. SIA-M5252) at 10 μg/mL (100 μL/well) can bind Rat CD47, Fc Tag (Cat. No. CD7-R5256) with a linear range of 2-20 ng/mL (QC tested).
