According to our SDS-PAGE result, we could see two band at around 41.36 kD and 39.41 kD, which are in line with the molecular weight of F3H and FLS. The two band only occurred in IPTG group, which confirmed with our induction. in keeping with the previous conclusion, the expression level of F3H and FLS after 12 h induction were slightly higher than that with 36 h induction. Taken together, we have successfully expressed FSH and FLS in E.coli.

Applications of BBa_K4236005

Protocol we used: 1. Verification of the sequence. The sequence we submitted here was come from (两种物种). In order to get better field, we has done codon optimization for E.coli expression for this sequence. We contacted with a biology company to synthesize the sequence. 2. We constructed it into a (请老师确认载体骨架) plasmid and transformed the plasmids into E. coli BL21(DE3). 3. After culture overnight, we picked a single colony added it into 4 ml LB medium with the corresponding antibiotic. The mix was then shook at 37℃ until OD = 600. 4. Dividing the liquid medium into 23 parts, adding 1 mM IPTG to two of them for inducing the expression 16℃ at 12 h or 36 h . The other one added nothing to serve as a control. 5. Centrifuged the bacterial solution at 12000 g, the precipitation was mixed with RIPA as a lysis buffer. Added loading buffer to heat at 96℃ for 10 min, underwent SDS-PAGE and Coomassie brilliant blue staining for expression test. According to our SDS-PAGE result, we could see two band at around 41.36 kD and 39.41 kD, which are in line with the molecular weight of F3H and FLS. The two band only occurred in IPTG group, which confirmed with our induction. in keeping with the previous conclusion, the expression level of F3H and FLS after 12 h induction were slightly higher than that with 36 h induction. Taken together, we have successfully expressed FSH and FLS in E.coli.
