I've got almost as many unfinished blog posts as manuscripts open on my desktop and some pressure to wrap up some things before others, but -- holy cow -- this is fantastic!
Not only do they pull off sequencing a protein, but pull it back in reverse it to do it again! Full de novo single protein sequencing from a single protein molecule. Sure, it's slow, but have you seen their solutions for speeding up their DNA sequencers?
I only x'ed out the one that, in my ever humble opinion, is dumb (it's a cheaper version with too many limitations to make it useful for anything I can think of). You can plug your single sequencer into your laptop with a MinIon (I only have an older one and its a little big for a thumb drive. Think about 1/3 the size of a small iPhone) and if you need to do more sequencing you can plug a bunch of them into a GridIon and plug that into your laptop. And if you need a crap ton of throughput you can plug several hundred of these things into a big box called a PromethIon.
I've been enjoying this blog for a few years now, but I feel I have to step in to defend the humble (if poorly named) Flongle. You can do a lot with 500Mb-2Gb of long read data - especially if you're interested in sequencing a few bacterial or small eukaryotic genome, but don't have enough samples to make a full MinION worthwhile. And they only needed 211 reads to identify the peptide variants - I've gotten 100,000+ from a Flongle before. For ~70USD, being able to confidently identify a protein, including single amino acid variants, using mostly tools/supplies you probably already have in your lab, with a machine that doubles as a DNA sequencer? I can see that being very useful for anyone doing protein expression & modification, e.g. monoclonal antibodies.
