Olchemlm probably means everything they carry is for "biochemistry". I am not familiar with many chemicals but I must agree that adenine sounds implausible to be used as a cytokinin.

The adenine I know is one of four DNA/RNA nucleotides.

Ah, no wonder you have "cis or trans" as your footer. I do not know what is isoprenoid cytokinins. Are they some types of aromatic substances? Ester of some sort.

It must be an almost impossible job to purify and identify those several proteins involved in their metabolism without advanced equipments. Do you use a PCR machine?

I have not the slightest how and what a "biochemist" does. I am trying to related myself with you with genetics. :lol: I was working with human blood, urine and faeces, and all possible testing and analysis with mammalian genes. Personally, I did not find them exciting. I got bored after a while. Maybe it is not my thing.

Olchemlm replied. They charge me 400g Triacontanol at 4,230.00 EUR (5,577.37 USD), 97%. I can forget about getting from them.

The most expensive Triacontanol I have yet to see is 18,000 USD for 400g of similar purity. I think the price is comparable to precious stones and minerals such as diamonds and gold. Frighteningly exorbitant.

Anyhow, Olchemlm cannot answer my question as to purity affecting the result. Most are only good at "selling" and not knowing what they are selling. Typical salespeople.

They know what are they selling, they just don't know all effects.

Anyway, 5500 USD is less than 18000 USD, isn't it? Do you need that much? Such chemicals are IMO used in at most micromolar concentrations.

Cis or trans? That's what matters.

You are correct. I am thinking of "more" in quantity so it could be cheaper, but I did not consider that PGR can fetch such a high price. Most chemicals can last longer and more stable in powder form, so no harm of buying a little more than needed.

Another thing is I must consider is the trial and error. I think you know there will be a waste with all the testing. If one particular concentration does not work, that will be thrown away and make a new solution with higher concentration. The more is used the more is wasted when no effect is shown.

Do not forget that I am going to spray on plants and they will be in the real world situations where many aspects are not constant as in the laboratory. Even more PGR is used to spray on plants than in tissue culture.
