CD3 Proteins
Highly active CD3 proteins including monomers, homodimers, heterodimers, and biotinylated
Product Features
High Protein Affinity
We verified the activity of our heterodimers, such as CD3E/G-His Tag and CD3E/D-His Tag, via ELISA and SPR.
Equal Expression of Subunits
We adopted a specialized design that ensures the two subunits of the heterodimers are expressed in equal proportions with greater than 95% purity.
Stability
We demonstrated via ELISA high consistency across batches and long-term stability of our products.
Applications
Antibody Discovery
Immunization
Antibody Screening
Functional characterization
Affinity Determination (ELISA, SPR, BLI)
