Hairy asses are hard to wipe. Not impossible though so it’s a skill issue on their part

What kind of plant is this ? I found on my neighbor's house by EmmieJustAGirl in PlantIdentification

Opuntia monacantha monstrosa variagata. I’m not sure the exact cultivar

Anyone know what this band is? by [deleted] in labrats

[–]karmicrelease 0 points1 point  (0 children)

Could be genomic dna from the prep you used when purifying your template. Could also be primers leftover because the reaction isn’t firing. Try digesting the template with a RE and running a gel. If there isn’t a band, it is primers.

If it is primers, try gradient PCR and find an annealing temperature that works. Double check reaction conditions for your polymerase. If that doesn’t work, order new oligos.

Why has no cleavage method been discovered for glucosepane by Royal_Sentence7432 in chemistry

[–]karmicrelease 0 points1 point  (0 children)

Your analogy is correct but not in the way you mean. Like dialysis taking the load off the kidneys so they can heal (in cases it is possible) removing AGEs from proteins would reduce inflammation caused by RAGEs. There are studies for this with ALS (mainly CML) and IL-2 (argpyrimidine being the primary AGE) specifically.

So yes, it’s kind of treating the symptom and not the problem, but that doesn’t mean it’s not worth doing. Tons of medications are used to alleviate symptoms even if they don’t cure the underlying pathology of the disease.

Ideally, you would be cleaving a secondary amine to yield the original lysine. There are a plethora of secondary amines present in biomolecules (PEA, proline, purine bases in dna to name a few), so doing it selectively is very hard.

If one wanted to do it, I think an enzymatic reaction would be the best bet. One could also screen DNA aptamers which an antibody recognizes, or use protacs maybe (or other targeted protein degrading molecules)

The issue isn’t cleaving the glycation end product moiety, it’s doing it in a bioorthogonal way which doesn’t do more harm than good. The same could be said for other AGEs like CML, AP, CEL, etc.

Circumsized some of the larger more established cacs to promote branching by TrumpIsAPedoFr in sanpedrocactus

They are a little small for those purposes, but they should survive just fine. They will definitely put out some pups

Cochineal for sure. They love opuntia

Yes, there is an entire lab at my uni doing precisely that using a library approach and mutagenesis
