Automated and DIY microplate on fabric
An automated 96 well microplate for fabric was made using a fluorescent microplate, 96 well tip holder and laser-cut cotton circles.
1. Spread a flat, wet cotton sheet on glass substrate of 96 well plate dimension.
2. 96 Wet cotton circles of 6.5mm are laser cut on glass substrate.
3. Remove the fabric. The circles of cotton stay on the glass substrate.
4. Place the glass substrate of cotton circles on fluorescent microplate such that all circles face the wells and align well.
5. Hold it tight and move the glass substrate laterally so that all the cotton circles fall into the wells.
5. Put the tip plate holder on the top of the microplate and adhere it to the microplate using a glue.
6. Cover it with a lid and the microplate is ready to use for experiments. The same can be done for other fabrics like silk, polystyrene, nylon etc.
Selected Peptides from Binding Domain Group
From approximately 20 sequences for 5 different fabrics each we picked total of 9 peptide sequence to pass on to Enzyme search group to fuse it with enzymes they are working on and study their efficiency in binding fabrics.
The peptides are named FBD 1-9 for Fabric binding domain - 1 to 9.
Out of the 9 sequences 5 are specific, i.e, one sequence specific for each fabric. The sequences were not selected based on the consensus sequence but their repeatition in that particular fabric or some unique feature in the peptide. and the other 4 sequences are non specific, found in multiple fabrics.
-
FBD1 - Is non specific, it is repeated in all 5 fabrics.
-
FBD 2, 3, 4- Repeated in all fabric.
FBD2-FBD3-
FBD4-
-
FBD5 - Specific to Wool, it was repeated 3 times out of 16 sequences.
-
FBD6 - Specific to cotton
-
FBD7 - Specific to Silk
-
FBD8 - Specific to Linen, the sequence was selected because it has multiple proline residues
-
FBD9 - Specific to polyester, it was selected because of its high number of positively charged amino acids
-
FBD10 - Picked from literature, Guo et.al, (2013) it will serve as a positive control - shown to bind to cellulose
-
FDB11 - Random amino acids put together(7aa) to be used as negative control.
