Cellsius

Cellsius is an open-source biology resource that combines a curated shop with a guided learning path for hands-on molecular biology. Its biotech skill tree helps beginners progress from sterile technique, culturing microbes, and microscopy to bacterial transformation, plasmids, PCR, and CRISPR gene editing. Each skill connects to suggested kits, equipment, and supplies, making it easier to choose what to learn and what tools to use.

The shop features products from makers such as The ODIN, alongside laboratory gear and consumables. Offerings include microbiology and genetic engineering kits, micropipettes, microscopes, centrifuges, agar plates, and other supplies. Cellsius also sells its own starter bundle, a digital protocol handbook, and a supporter membership. Its educational materials include beginner guides and an open library of step-by-step protocols.

Cellsius emphasizes learning with non-pathogenic, BSL-1 organisms and education-grade materials, and states that its products are not for clinical, human, or animal use. Its aim is to make biology more approachable through practical projects, clear guidance, and curated resources for home learners, classrooms, and community biolabs.
