Cellsius is a curated shop and skill tree for hands-on molecular biology. Follow the path from your first petri dish to CRISPR gene editing — and get the exact kits, gear, and reagents that teach each skill.
Some links are affiliate links — we may earn a commission at no extra cost to you. How this works.
Skills build on each other. The skill tree shows what to learn next — and what to buy to get there.
We hand-pick trusted kits and gear from makers like The ODIN, plus lab staples, so you don't have to guess.
Only non-pathogenic, BSL-1 organisms and education-grade materials. Never for clinical, human, or animal use.
The tree turns "where do I even start?" into a clear route. Each node below is a real, teachable skill — click it to get the kit or tool that teaches it, or open the full interactive skill tree to explore every branch.

We do not sell or promote human pathogens, controlled organisms, or anything intended for use in or on the human body. Our picks use the same non-pathogenic strains found in school and university teaching labs.
Shop these items are our picks from trusted makers and retailers — you buy on their site through an affiliate link, and we may earn a small commission. Our Kits come from Cellsius and sell here directly, with secure card checkout.
Yes. Everything we list uses non-pathogenic, biosafety level 1 (BSL-1) organisms — the same harmless strains used in classrooms worldwide. Each kit includes safety and disposal guidance. We recommend users be 16+ or supervised by an adult.
No. The skill tree starts from the very basics and tells you exactly what to learn and buy next. Beginner kits include everything you need. The Equipment section covers affordable gear when you're ready for more.
In most countries, working with non-pathogenic organisms for personal education is legal. Rules vary by region, so please follow your local laws. We never list regulated organisms or anything for use in humans or animals.
Affiliate links cost you nothing extra — the price is the vendor's normal price, and we receive a small commission that helps keep our guides free. Prices shown here are indicative. The live price is always on the vendor's page.
Stripe handles checkout, so your card details never touch our servers. This demo storefront runs in "demo mode" until you add Stripe keys — buttons fall back to an email order in the meantime.
