NeoFv513 VH-LinY12H-VL

NeoFvs are engineered antibody fragments. An scFv is defined as the variable domains of a full length antibody connected via a flexible linker. A NeoFv is a name given by iGEM 2022 team IISER-Pune2_India to scFvs with a small peptide extension that binds to the human neonatal Fc receptor (or FcRn receptor). Such scFvs with an FcRn binding peptide have recently been described in literature [1] with potential to overcome the size problem of scFvs, and extend their half life of circulation in the human body.

NeoFv513 VH-LinY12H-VL is one such NeoFv derived from the Ab513 antibody targeting the envelope protein domain III epitope of the Dengue virus. A NeoFv derived from Ab513 can ideally be a therapy for Dengue fever.
