Human Claudin 18.2 Protein
Design & engineering, expression & purification
Based on structure constraints and structure modeling design, Kactus Biosystems display the functional domain of the transmembrane Protein CD20 which has the full bioactivity with the reference antibody Rituximab,deteremined by ELISA and SPR assay.
The MHC/antigenic peptide complexes designed and developed by Kactus Biosystems are expressed from mammalian system. The development short the expression time, no need to be refolded , have the post-translational modification and have the highest bioactivity. They are good tools for the intracellular tumor antigens.
