But how much are the enzymes going to cost?

I don't understand the downvotes, because it seems to be an interesting question, and the article is not very clear.

Is $900 the price for the gadget alone? Is the price for the gadget + 1 time enzyme kit? Is it the price of each repetition of the analysis (enzyme + disposables), but there is an additional initial cost (gadget)? This thing is reusable, or you must buy a new whole kit each time?

Ars had its own article on this saying that you do not need enzymes. It's forcing the molecule through a tiny pore and reading the change in an electrical signal. That said, one problem mentioned is that the error rate is quite high.

This article says:

"Both GridION and MinION operate using the same technology: DNA is added to a solution containing enzymes that bind to the end of each strand. When a current is applied across the solution these enzymes and DNA are drawn to hundreds of wells in a membrane at the bottom of the solution, each just 10 micrometres in diameter."

Perhaps this method use fewer enzymes than the old one.
