Fusion between the ice nucleation protein (INP) and annexing V. RFP is found in the sequence to facilitate localization of plasmids. Part made using the INP submitted by the Edinburg team 2011 Part:BBa_K523013.

Experimental set-up

Bacteria containing INP-Annexin V in a high copy plasmid (pSB1C3) or a low copy plasmid (pSEVA371) were cultured in Lysogenic Broth (LB) with 50 µg/mL (for pSB1C3) and 12.5 µg/mL (pSEVA371) of chloramphenicol overnight at 37&ord;c with a shaking of 200 rpm. The cultures were emulsified with EmulsiFlex-C3 to obtain a cell lysate. Then, a Western blot was performed. Two different conditions were tested for each cell culture:

  • Cell lysate with no further treatment (crude).
  • Cell lysate that was centrifuged for 10 min at 10,000 rpm to separate the soluble proteins from the membrane fraction (supernatant).

Results

As can be seen in Figure 1, there is expression of INP-Annexin V inside the cell and it seems that it is present on the membrane fraction.
