Biotinylated Cynomolgus IL-2 R beta/CD122 Protein (Primary Amine Labeling) is expressed from HEK293 with His tag at the C-terminal. It contains Ala27-Asp239.[Accession | Q38J85] |
|
Molecular Weight |
The protein has a predicted MW of 25.6 kDa. Due to glycosylation, the protein migrates to 40-50 kDa based on Tris-Bis PAGE result. |
|
Endotoxin |
Less than 1EU per μg by the LAL method. |
|
Purity |
> 95% as determined by Tris-Bis PAGE |
|
Activity |
SPR Data: Biotinylated Cynomolgus IL-2 R beta, His Tag captured on CM5 Chip via Anti-His Antibody can bind Human IL-2, No Tag with an affinity constant of 0.148 μM as determined in SPR assay |
|
Formulation |
