WebFor a gene to give rise to its protein product, an expression vector must be used that contains the appropriate pieces for a host cell to produce the protein. In the case of a mammalian cell, a standard mammalian expression vector will still contain the origin of replication, multiple cloning site, and selectable marker, but it will also need a promoter … Web11 de abr. de 2024 · Here the authors report six bacterial Cas12f1 proteins with nuclease activity in mammalian cells, ... in HEK293T cells.
