CRISPRy to the rescue!!
The CRISPR/Cas9 system can be a beacon of hope for genetic diseases but can also be the harbinger of doom if used unethically. We investigated on the prospects of this technology by surveying the opinion of Singapore's community. On the other hand, we have combine techniques of Computer Aided Design(CAD) sofwares and PyMOL to customise proteins for 3D printing.
"Protein 3D Printing" For Dummies
We're lucky to be in the era of 3D printing. In our opinion, science education are not only fun but cognitively stimulating when there's a model for us to play with. Hence, we decided to design 3D models of Cas9 during our exhibition. For 3D printing, all files have to be converted to .stl fromat. From the web, we have found that we can convert a .pdb file to .stl file with USCB's Chimera software.
Hence, we were very excited and we tried to print a small protein, insulin, in it's alphe helical structure as a start! However, we met few challenges.
To solve our problem, we found out that PyMOL is able to make our structures thicker and, hence, more rigid. After thickening our loop regions in PyMOL. We have to export our desired structure in .vrl format and then convert to .stl with Chimera.
Now, we can have thicker and more stable helices.
When we started to know how to do print a protein, we came out with an idea to put joints into the protein to make our models more interactive and less static.
