its International PCR Day - amplify something !
Marking the date of the first PCR experiment. Like any good first experiment . . .it failed.

@TakethatCt Even if it reasonably quick cycling at a minute per cycle, that’s a month to get results. “I put that PCR on a week ago, we need results”
“yeah, it’ll be a few more weeks yet . . . “

Highlander was released OTD in 1986 - A THREAD
The opening sword fight is supposed to take place in Madison Square Gardens' car park, it's actually a London fruit market. The sparks were created by having wires up the actors arms attached to car batteries.

@TakethatCt @TerryHaffnerMD @MarkDavidsonAfr @DrNice2022 . . . and Mullis' current resting method means he is unlikely to say anything in future either !

@ochoa_corona Gotta love HRM Francisco ! But why not use a rapid DNA extraction buffer with so many insects? Buffer, insect, 95deg 2 mins and into HRM.

The latest repliqa HiFi ToughMix feedback from a New Zealand user?
". . .was using it to amplify up gene clusters ( around 10 -15 kb) to be sequenced using an oxford nanopore. The PCRs looked great and didn't have any errors in them"

@TripleVexed @DocDeezWhat @nzfirst After 25 it’s garbage? No, it just means virus is present at a lower level than if less than 25. A Cq of 26 still represents thousands of viral copies present in the sample

[John Mackay @dnatured]

@TripleVexed @DocDeezWhat @c_plushie @nzfirst Where’s that interview? Yes, NZ labs tested out to 45 cycles, no it didn’t take 30 mins (normally > 1 hour)

CYBER Monday? Yeah, but dnature has *SYBR* Monday ! #qPCR @Quanta_bio @SolisBioDyne

@ilyaskhan @p_maverick_b Not quite. He was on his way to his holiday house when he had the thought. A friend of his had started what is now @LGCBiosearch and had made the first automated synthesiser, and put one in Kary’s oligo lab
