表達(dá)區(qū)間及表達(dá)系統(tǒng)（Source） |
Cynomolgus/Rhesus macaque CD19 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Gln21-Trp291.[Accession | A0A2K5W8L9] |
|
分子量大?。∕olecular Weight） |
The protein has a predicted MW of 30.96 kDa. Due to glycosylation, the protein migrates to 50-70 kDa based on SDS-PAGE result. |
|
內(nèi)毒素（Endotoxin） |
Less than 1EU per μg by the LAL method. |
|
純度（Purity） |
> 95% as determined by SDS-PAGE and HPLC. |
|
活性（Activity） |
SPR Data:Anti-CD19 Antibody, hFc Tag captured on CM5 Chip via Protein A can bind Cynomolgus/Rhesus macaque CD19, His Tag with an affinity constant of 0.24 μM as determined in SPR assay . |
|
制劑（Formulation） |
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
