Thermal Cycler Engineering
Our re-design is based upon the Open PCR system originally designed by Josh Perfetto and Tito Jankowski.
Correctly positioning the heating plate on the plastic sample containers proved to be difficult. To make this product more user friendly a button would be added to the heating plate. When in contact with the samples the button would signal the user via the LED display that the heating lid was correctly positioned.
This picture of the roof assembly shows where the button will be added. The blue circle would contain the button that would, when in contact with the plastic containers below, signal to the user that the heating plate was correctly positioned.
This is another image of where the button would be positioned. The relative size is also accurate as it would need to be able to detect a sample anywhere in the heating block.
The original PCR machine was make of lightweight balsa wood. While this was inexpensive it was prone to splitting along the grain and staining. The new PCR machine would be made with a stronger plastic body that would better resist wear and tear and resist becoming stained with liquids commonly seen in a lab.
The original PCR machine had a cord that was slightly short and required an extension cord in some cases. The new PCR machine would have a longer cord so as to avoid this problem.
The original PCR machine had a limited storage capacity that proved to be a problem in our large class. To make the product more attractive to educators the new machine would have double the capacity. To help minimize the cost of this addition the new product would use the same PCR blocks as before, merely double the number. To accommodate the extra load the heater and cooler would likewise need to be doubled.
The original PCR machine was slightly difficult to understand, again to make the product more attractive to educators the new product would have key parts engraved with their names. This would allow a student to quickly identify pieces and deduce their function. No picture is shown for this proposed addition.

Background on Disease Markers
Alzheimer's disease, a form of dimentia in which brain function is lost gradually over time, is associated with the SNP rs121918396. The sequence associated with Alzheimer's is TAG, while a normal sequence is TGG.
