Sequencing and sequence alignment of K3503006

Figure 1. Representative sequencing results of K3503006

To future confirm that our constructs have the correct sequence, we send our clones (with positive PCR results) out to sequencing.
The sequencing results show that we have successfully assembled target genes K3503004 to the vector (pET-11a).

Successful expression of K3503006

In order to validate the protein expression of K1608000, K3503006 and K3503004, we performed SDS-PAGE (coomassie blue staining) and Western blot analysis. To make K3503001, K3503007 and K3503008 easily detectable via Western Blot, we designed our constructs to include a “His tag” which is targeted by a commercially available antibody. With the SDS-PAGE and western blot (anti-his for his-tagged protein), we found successful expression of K1608000, K3503006 and K3503004
Before performing the SDS-PAGE, we grew up our engineered E. coli cells containing a plasmid with K1608000, K3503006 and K3503004 under control of the T7 promoter. Cells were induced with0.1mM IPTG until either OD0.4 (wavelength: 600nm) at 30°C. After expression, cells were then lysed according to our protein extraction protocol, and supernatant and pellet were collected for the SDS-PAGE.

For more experimental details of the Western Blot and SDS-PAGE, please see protocol.

Fire retardant test of K3503006

The test subject was in the size of bed sheet in 300*130mm and the average Moisture content% is 13.55%-14.37%. As demonstrated on Fig 3, all of our engineered flame retardant displayed a significant improvement compared with the water control.

Figure 4. Flame retardancy test using wood.

As demonstrated in Fig 4, all of our engineered K3503001, K3503007 and K3507008 flame retardants displayed a significant improvement compared with the water control.
