Fun fact: DNA sticks to plastic really easily, so it is common practice to put "carrier DNA" in biotech products that are only DNA. This carrier DNA is at a much higher concentration than your DNA of interest and fills up the plastic so the DNA we care about doesn't. Salmon sperm extract is a common carrier DNA.
Fun fact: no it does not. It sticks to glass well, but it only slightly adheres to polypropylene after spinning over 10,000g of force. That's why you add salt to DNA precipitation. Know every reagent in your protocol and why it is there.
Funfact: sperm contains protamin, the antidote for heparin which is used for anti coagulatory properties in medicine. During cardio vascular surgery you get a shit ton of heparin so they can perform the open heart surgery (so the heart lung machine doesn't get clogged). After the surgery you get protamin so you do not bleed to death. This protamin is often sourced from salmon sperm. If you have strong fish allergies you could theoretically react on it but it's not very likely.
Fun fact the best invisible ink has traditionally been semen. British intelligence switched to other stuff after their tabloids started making fun of them for it at one point, 20th century sometime idk. Lemon juice sort of works too, put a letter on a radiator and the invisible ink becomes visible.
I follow a lot of skincare communities online and whenever I see a product with PDRN, I cringe. Who even thought of making skincare products with it? What company approved the idea? How on Earth did any marketing team convince anyone to buy it is beyond me.
To be fair, they didn't know that ambergris was an excretion of the whale until long after they started using it for these purposes. It was just "that waxy thing we find floating in the ocean." Also, it's apparently not vomited, but defecated.

Is only salmon acceptable? I have a cheaper source from another animal, also cladistically a fish.

The active ingredient is DNA, which they could get from any plant far easier without smelling like Gwyneth Paltrow's vagine.

If your friend waits a few hours, it should smell kinda like salmon....

it literally does, and here's data from Promega testing a eppendorf lo-bind tubes to oxygen tubes. https://worldwide.promega.com/-/media/files/resources/conference-proceedings/ishi-23/poster-abstracts/53-poster.pdf?rev=62368fd4fbb44e95a6d760af2b0cfa5d

Hi, my name is salmon, and I'll be doing your skin care today

Salmon here, you guys are gross

You have to admit it's probably the best part of being a salmon.

A trick they learned from old Sea Men no doubt. These johnny cum latelies are pretending like they just invented this.

Pretty much everyone was booting off at the image of the cows getting artificially inseminated the other day.
Saying it's rape and animal torture and that.
Yet wiping salmon spaff all over your face in the name of vanity is apparently totally fine

So we all agree that some guy got caught blowing a salmon and made this up as an excuse, right?

I mean, bat shit is a common ingredient in make-up and whale barf is used in high end perfumes. The cosmetic industry uses a lot of gross products.
