Recombinant Human LILRB2/CD85d/ILT4 Domain1&2 Protein is expressed from HEK293 with His tag at the C-terminal. It contains Gln22-Val229.[Accession | Q8N423-1] |
|
分子量大小（Molecular Weight） |
The protein has a predicted MW of 24.2 kDa. Due to glycosylation, the protein migrates to 25-30 kDa based on Tris-Bis PAGE result. |
|
内毒素（Endotoxin） |
Less than 1EU per μg by the LAL method. |
|
纯度（Purity） |
> 95% as determined by Tris-Bis PAGE and HPLC |
|
活性（Activity） |
ELISA Data: Immobilized Human LILRB2 Domain1&2, His Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Anti-LILRB2 Antibody, hFc Tag with the EC50 of 16.6ng/ml determined by ELISA. ELISA Data: Serial dilutions of Anti-LILRB2 Antibody were added into Human LILRB2 Domain1&2, His Tag : Biotinylated Human HLA-G Complex Tetramer, His Tag binding reactioins. The half maximal inhibitiory concentration (IC50) is 0.43μg/ml. SPR Data: Human HLA-G Complex Tetramer, His Tag immobilized on CM5 Chip can bind Human LILRB2 Domain1&2, His Tag with an affinity constant of 6.5μM as determined in a SPR assay |
|
制剂（Formulation） |
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. |
|
重构方法（Reconstitution） |
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
储存条件
