Paper that bubbled up on the Nepetalactone sstack comments section. Image

Note the cells ‘rescue’ the linear DNA with integration.

The plasmid they used in the above study doesn’t have an SV40 72 base enhancer element that Dean et al demonstrate to enhance these efficiencies due to its nuclear targeting sequence. Image
They cut the vector at BsaI leaving that red arrow.
They other 25-40% of the vector has no GFP tracer for integration. That will under estimate the linear risk if they normalized based on molecules.

The vector also has this in it.
Not a NTR

I watched this last night as people had questions about the gene therapy described in it.
A thread on my take
Background.
Im against the drug war. People should be free to Biohack. Even if the government mandates water, I have a problem with it. Not the water but the force and threat to freedom.
I'm glad Bryan is on this journey and sharing what he finds.
I don't care if he sells stuff on the way. Voluntary economic interactions are legit. People who like to control the narrative will complain.

I couldnt do 100 supplements/day but maybe he'll figure out the key 4-5 that do 90% of the work for others.

Profiling circulating DNA is a thing. I’m just skeptical of the tox seen with LNP delivery of mRNA.
We took the cover of Science Translational Medicine in 2010 with profiling circulating tumor DNA.

@P_J_Buckhaults just sent me this.

@P_J_Buckhaults The reason this is a Holy Sh$t is that the resolution and sensitivity is a game changer.
They dont need to load up 100X the dose to track this. Image
@P_J_Buckhaults Would be nice if they looked at Ovaries/Testes Image

🔥My Review of the Recent FDA-Student DNA contamination Paper.🔥 Image
6-470X the limit but this higher limit is from UV spec which is likely inflating the signal Image
The Qubit data did not run DNaseI standards.
This leads to under reporting the DNA 70%.

@blind_nut @DopplerEffect93 @TheStockRizzer @Crash_the_Flash @Double_Christ @MdBreathe Matthew is too incompetent to map reads.
If he could map reads he’d realize Chakraborty doesn’t need peer review because he is using data from 2 peer reviewed papers.
Doah.

@blind_nut @DopplerEffect93 @TheStockRizzer @Crash_the_Flash @Double_Christ @MdBreathe DNA doesn’t need to get into the nucleus to cause problems.
But it does. Image
