You're getting downvoted but I think it's a fair question actually. I'd assumed they were referring to tapping into non-stressed supply chains. What you mention is valid though and something I'm curious about as well. Are the consumables reliant on chip fabrication? I don't think PCR machines themselves are scalable, maybe chips are more scalable than the optics systems for qPCR, but a valid point about whether the consumables are more scalable as well.
