Ice Nucleation Protein(INP)

ice nucleation protein(INP) is a kind of transmembrane protein, which can help proteins to play their role outside the membrane.

Data

Fig.1

According to Fig.1-1, all the fragments designed have been successfully made, including S1&S2, which are Silicatein combined with INP, and P1&P2, which are S010_pET28b-csgA-linker-mfp5-7His(pET).

Fig.2

Fig.1-2 represents the results of gel electrophoresis to test the fragment after Gibson Assembly. The length is about 600bp, which, together with the results from sequencing, indicates a positive outcome.

Fig.3

Fig.1-3 represents qualitative OD values, showing that there is sufficient amount of silicatein produced, since: •Both NC Control are darker (NC1 remain as yellow which indicates that it needs MORE NaOH to turn blue, it contains more acids). •Both silicatein mixture (with / without homogenization) have higher OD810nm, meaning that there are more bacteria inside the test tube (the solution is thicker / not as clear as NCs).

Fig.4

Fig.1-4 shows the results from TEM testing. Dark proportions represent silicon dioxide produced on the surface of cells.
