There is much more to R-Phycoerythrin than its distinctive red colour.

Alongside its established use as a fluorescent protein, research into its antioxidant properties is creating interest across areas including cosmetics and skincare.

RubySea brings this naturally derived compound from Asparagopsis algae into a controlled, traceable production environment here in Fremantle.

Award-winning science is only valuable if you can turn it into something the market can use.

SeaStock has spent more than a decade developing the science behind two commercial products: RubySea and AlgaToro.

From pharmaceutical diagnostics and cosmetics to livestock methane reduction, we are now focused on taking that science to scale.

Built in Fremantle. Designed for global markets.

For buyers sourcing R-Phycoerythrin, the question isn't simply how pure is it?

It's also where did it come from, how consistent is each batch, and can you rely on the supply?

SeaStock's land-based process gives us control from cultivation through to extraction, creating a highly traceable and consistent source of R-Phycoerythrin.

What does a day inside an Australian biotech company actually look like?

From cultivation and high-precision extraction to testing under the microscope, our Fremantle team is working every day to turn Asparagopsis algae into commercially valuable products.

This is the science behind SeaStock.

Most people assume algae comes from the ocean. At Seastock, we do things differently. Our Asparagopsis algae is cultivated entirely onshore, in a controlled facility in Fremantle, Western Australia.

Precise conditions. No ocean contaminants. Consistent, high-purity output, batch after batch. That is the foundation of everything we produce.

Flow cytometry. Here is the science behind why RubySea matters.

Flow cytometry is a technique used in diagnostic laboratories to analyse and sort cells, detecting specific markers using fluorescent labels.

R-Phycoerythrin, the compound behind our RubySea product, is one of the most widely used fluorescent labels in flow cytometry because of its exceptional brightness and stability.

SeaStock produces RubySea at pharmaceutical grade from Asparagopsis algae cultivated onshore in Fremantle, WA. A naturally derived, consistently pure fluorescent label that diagnostics manufacturers can rely on.

Livestock account for approximately 14.5% of global greenhouse gas emissions.

Cattle methane represents the largest proportion of that total. And as carbon commitments tighten and sustainability expectations on the agriculture sector increase, the demand for proven, natural methane reduction solutions is growing fast.

AlgaToro, SeaStock's trademarked natural feed ingredient derived from Asparagopsis algae, is already accredited and commercially ready.

The market is there. The product is here.

SeaStock was built on a simple belief.

That algae, cultivated and extracted correctly, could solve real commercial problems across multiple industries.

From establishing land-based Asparagopsis cultivation in Fremantle to developing two trademarked products, AlgaToro for livestock methane reduction and RubySea for pharmaceutical diagnostics, the journey has been about turning science into something the market can actually use.

Here is how it started.

The cosmetics industry is shifting. And R-Phycoerythrin is at the centre of it.

R-PE, the naturally occurring compound behind our RubySea product, is one of the most vibrant natural pigments on earth, with antioxidant properties making it increasingly sought after in premium cosmetics formulations.

Produced in our controlled, land-based Fremantle facility, RubySea offers cosmetics brands a sustainably cultivated, pharmaceutical-grade ingredient they can trust.

Natural origin. Proven bioactivity. Consistent purity.

Not every algae species is commercially viable. Asparagopsis is different.

It naturally produces two of the most commercially valuable bioactive compounds in marine science today

- Bromoform - the active ingredient in AlgaToro, our trademarked methane-reducing livestock feed.

- R-Phycoerythrin - the pharmaceutical-grade fluorescent pigment behind RubySea, our diagnostic product for life science.

Cultivating Asparagopsis at the quality and consistency our clients require demands a controlled, land-based environment. That is what we have built in Fremantle.

And it is not easy to replicate.
