| − | Antimicrobial peptide (AMPs) has an extensive ability in disinfect. Unlike antibiotics, AMPs use chargeability puncture the cell membrane to kill the bacteria therefore by passing bacterial antibiotic drug resistance mechanisms. <a href="https://2015.igem.org/Team:TCU_Taiwan/Project/Overview#tcu_references_1">[1]</a> Two kinds of AMPs were selected as our reagents: Epinecidin-1 and Signiferin. </br>
| |
| − | Epinecidin-1 is a peptide comes from <I>Epinephelus coioides</I>, and Signiferin is comes from <I>Crinia signifera</I>. Both of them are extracted from the skin mucus. In addition, epinecidin-1 has the ability to help wounds healing and has been proven by animal studies. <a href="https://2015.igem.org/Team:TCU_Taiwan/Project/Overview#tcu_references_2"> [2]</a> Moreover, signiferin have great ability in disinfect Methicillin-Resistant <I>Staphylococcus aureus</I> (S. aureus), and had already been kindly proved by the TU-Delft 2013 iGEM team. <a href="https://2015.igem.org/Team:TCU_Taiwan/Project/Overview#tcu_references_3">[3]</a>Combining these two properties, we believe that can alleviate the serious problem of skin injury.</br>
| |
| − | To produce AMPs and control AMPs expression, we apply the Lac operon and ligate the DNA of signal peptide into E. <I>coli</I> to help AMPs secret into culture medium. <a href="https://2015.igem.org/Team:TCU_Taiwan/Project/Overview#tcu_references_4">[4][5]</a> Next, to prove that AMPs have the extensive ability in disinfection and helps the wound healing, selected cells and bacteria were tested <I>in vitro</I>, including the squamous epithelial cell and endothelial cell of the blood vessel and MRSA, and mice were used <I>in vivo</I>. Ultimately, create a wound dressing based on the above procedure.</br>
| |
| − | An excellent dressing made of AMPs will make a fast recovery.</br>
