[[5µg,ABP-FP-TPNCS]] pNCS-mTFP1 is a bacterial expression vector that constitutively expresses 6xHis-tagged mTFP1 in E. coli. The properties of mTFP1 are superior to those of the commonly used Aequorea victoria variant ECFP and which can be easily detected in mammalian cells using standard CFP filter sets.
