PCR

The result of PCR is shown in Fig.1. All PCR was performed by primers in table 1. All PCR were succeeded. We used PrimeSTAR Max premix for amplification.

Cell-free expression

Here we show the result of expression. (Fig. 4~7) Seq.2 (monomer RFP, mRFP) was expressed well in PURE system and slightly expressed in myTXTL. Seq.1 (polymer RFP, pRFP) has no fluorescence.

Fig.4 Expression in PURE system (No UV)

P: Positive (DHFR gene), N: Negative (Water), tem.: Template DNA

mRFP tem. and mRFP PCR was slightly turned into red.

Fig.4 Expression in PURE system (No UV)

P: Positive (eGFP), N: Negative (Water)

Positive (eGFP) shows green color.

Fig.4 Expression in PURE system under UV

P: Positive (DHFR gene), N: Negative (Water), tem.: Template DNA

mRFP shows the clear fluorescence. mRFP tem. and mRFP PCR shows the same result. mRFP shown in the figure is mRFP tem.

Fig.4 Expression in mtTXTL under UV

P: Positive (eGFP), N: Negative (Water)

Positive (eGFP) turned into green.

SDSPAGE

We performed SDSPAGE to confirm whether pRFP was expressed or not. The result is shown below.

Fig.4 SDSPAGE

As a result of SDS-PAGE, both myTXTL and PURE system shows the intense expression of the protein. In PURE system, we could see the monomer RFP. With the eye, a slight expression of mRFP in myTXTL was confirmed but not in SDSPAGE. In both cell-free system, the long-chain protein and mRFP was not confirmed with Seq.1.
