mfp5-alpha casein-RFP

This is a composite part designed that adding red fluorescence protein(E1010). Also, we added the mussel adhesion protein (K308902) to enhance the adhesion of the protein to have a better fire-defending. The protein sequence in this part is based on Alpha s1 casein (K2924026)

Successful expression of K3503011

In order to validate the protein expression of K3503009, K3503010 and K3503011, we performed SDS-PAGE (coomassie blue staining) and Western blot analysis. To make K3503009, K3503010 and K3503011, 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 K3503009, K3503010 and K3503011. Before performing the SDS-PAGE, we grew up our engineered E. coli cells containing a plasmid with K3503009, K3503010 and K3503011 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.
