Nice, economical protocol. To me the only really questionable step is the HotShot extraction - it doesn't sound like long-term DNA preservation is very good. Any new ideas on that?

Rudolf Meier3 years ago

This protocol is optimized for speed. If high quality DNA is needed for other purposes, one has to add the time for DNA extraction to the 6 hours.

We learned it from you and it really works like this. Awesome. Thanks 👍

@EckartStolle The future is here ☀️ Great work @RudolfMeier15 and team 👍🏼

Approximate total cost for setup minus typical lab materials?

Rudolf Meier3 years ago

Cost differs a lot between countries and is best determined for each country (but rough consumable costs are in the paper). The manuscript also disucsses how to trade off cost for time given that faster always means more expensive.

Out now: Real-time DNA barcoding with MinION! DNA barcoding isn't only for fancy labs - you can now discover global biodiversity in your kitchen while frying an egg (almost)! Reminds us of Dorothy Parker´s "Creativity is a wild mind and a disciplined eye"

🧬A new imaging technique developed by the Liu Lab uses a novel DNA barcode system to track hundreds of RNA & protein molecules in single cells within thick biological samples, providing a full picture of how these structures are organized inside tissues.

I will not rest until he is in prison.. (NEW) Fauci says it’s a LIE the mRNA COVID Vaccines Alter your DNA 🔴 1.) In Arizona, The GOP "Ban the Jab" resolution was passed calling the Covid Vaccines a Biological Weapon which Alters your DNA ( 🔴 2.) The Surgeon General of Florida sounded the Alarm that the mRNA Covid Vaccines are Altering and Installing Foreign DNA into your Cell’s —— “These vaccines are the ANTI-CHRIST of all products” • The DNA hangs on with the mRNA and is getting delivered into people’s cells with the lipid nano-particles… Therefore BILLIONS of DNA fragments are literally changing your own DNA —— “The more you get it… the more DNA fragments enter into your cells” (Video: 🔴 3.) The Florida Grand Jury report on Covid-19 finds there were excessive amounts of DNA Contamination in various mRNA Covid vaccine batches… DNA Contamination like this “can become incorporated into the genome of the recipient”, hence, it alters your DNA. (Source: 🔴 4.) Pfizer’s own CEO Albert Bourla bragged about the "DNA editing" potential of mRNA vaccine technology • “There’s a third application which is for people that they are born with a mistake in their DNA code.“ (Video: I can go on and on… Fauci Clip

🧬🦎EVOLUTIONARY CONVERGENCE🐊🧬 Is it really that hard to believe humanoid Reptilians exist? Some scientists hypothesise that evolution is not random and will eventually evolve based on optimum designs. The humanoid form is an excellent design and is ubiquitous throughout the universe; standing upright with 2 legs, 2 arms, 2 ears, 2 eyes, 1 head, 1 nose, 1 mouth etc. is the norm and seems to be written into the fabric of our reality/matrix. While there are indeed many aliens out there that break the mould and look vastly different than us, Homo sapiens are part of a much larger family and we share common DNA with other humanoid races. The creation of Homo sapiens was a group effort by multiple aliens/ETs (see below) but that doesn’t mean evolutionary convergence isn’t possible over long periods of time. Most Earth scientists are still uninformed regarding this fascinating subject but they will soon learn the truth once we make official contact.🧬🦎👽🐊🧬 “May you live in interesting times.” ~ Ancient Chinese curse

🚨 Anthropic's CEO: "software engineering will be fully automated in 12 months." two types of people right now: type 1: uses Claude Code with basic prompts. scared about the future. type 2: knows all 35 commands, tricks, and workflows. ships faster than a team of 5. type 1 gets replaced in 12 months. type 2 does the replacing. I wrote a full guide on how to start. zero experience needed.
