  • Insert Size (bp)
  • Mutation
    Ci-VSP contains R217Q mutation; super ecliptic pHluorin contains A227D mutation. The A227D mutation increases the fluorescence response magnitude. We replaced residues 71-91 within CiVSD with an amino acid sequence (KSRITSEGEYIPLDQIDINV) from the Kir2.1 channel Golgi-to-plasma membrane trafficking signal. The Kir 2.1 channel ER export signal sequence (FCYENEV) was added to C-terminus of super ecliptic pHluorin. The sequence is codon optimized using mammalian codon preference.
