ChromoTek offers two bispecific T cell engagers:
- anti-Her2 x anti-CD3ε:
Nanobody (VHH) against human Her2 fused to a single-chain variable fragment (scFv) against human/cynomolgus CD3ε
- anti-CEA x anti-CD3ε:
VHH against human CEA fused to a scFv against human/cynomolgus CD3ε
Binding to target molecules has been characterized in-vitro. For in-vivo assays the bispecific T cell engagers are endotoxin free (endotoxin level < 0.005 EU/mL).
