A SOE-PCR method of introducing multiple mutations into Mycoplasma gallisepticum neuraminidase

A modified splicing with overlap extension PCR (SOE-PCR) was generated to introduce 21 TGA to TGG at Mycoplasma gallisepticum MGA_0329 gene. The recombinant protein was successfully expressed and retained neuraminidase activities, indicating that SOE-PCR is a rapid and highly efficient method of introducing multiple mutations into large M. gallisepticum genes.
