Plant Cell Technology Your go-to hub for cutting-edge plant tissue culture products, expert knowledge, innovative techniques, and hands-on master class education! 🌱🧫

Plant Cell Technology, Inc. develops, produces and markets innovative solutions for commercial and research plant tissue culture laboratories and plant growers. Our flagship product, PPM™ (Plant Preservative Mixture), is a broad-spectrum biocide/fungicide for plant tissue culture. PPM™ (Plant Preservative Mixture) is a heat stable preservative/biocide that, based on the dose, effectively prevents or reduces microbial contamination in plant tissue culture. At optimum doses, PPM™, does not impair in vitro seed germination, callus proliferation or callus regeneration. Despite the most stringent use of sterile techniques and aseotic conditions, the contamination of plant cell and plant tissue cultures remain a persistent problem. PPM™ prevents the germination of both bacteria and fungi spores. Because it's heat stable, it can be autoclaved with media. PPM™ can be used as a standard ingredient in plant tissue culture media. PPM is less expensive than antibiotics and can prevent fungal contamination simultaneously. PPM is both biostatic and biocidal. In addition to inhibiting airborne, waterborne and human contact contamination, it also can be used to reduce endogenous contamination.

The class you kept asking for is back!

Our spicy tomatoes master class last went live in December last year, and we’ve heard you loud and clear. Round two is happening.

Two full days, live with Francisco Palacios, covering the techniques culturists use most: media prep, sterilization, meristem work, pathogen testing, embryo rescue, and hands-on micropropagation.

📅 November 21 to 22, 2026
🕐 1 PM to 7 PM EST

That cross you were sure would fail? Embryo rescue can save it 🍅

Pull the embryo before it aborts, grow it in vitro, and keep genetics you’d otherwise lose. It’s one of the most valuable techniques for anyone breeding spicy tomatoes.

We teach it live in our Specialty Plant Master Class, and this is the only online session of the year.

Apical meristem dissection, sped up 3.5x 🔬

Our PCT intern isolating the actively dividing tissue at the very tip of the shoot. Because these cells are so young, meristem culture is one of the go-to techniques for producing clean, pathogen-free plants and preserving elite genetics.

What you’re seeing in seconds takes real time, steady hands, and a lot of patience. Every culturist remembers their first meristem.

Your tissue culture looks perfectly clean. Then, two weeks later, the bacteria show up. What happened?

Endophytic bacteria can live inside plant tissues, meaning surface sterilization may not be enough to eliminate them. They can remain hidden and only become visible once the explant is established in culture.

So, how do you manage contamination that keeps coming back?

Our latest blog looks at how to detect and manage endophytic bacterial contamination, from choosing cleaner source material and indexing cultures to understanding the limitations of antibiotics and other approaches.

Building your own tissue culture protocol isn’t as simple as finding a recipe and following it.

The right protocol depends on the plant species, explant, medium, PGRs, and even the conditions in which the culture is grown.

If you’re working with a plant that doesn’t have a well-established protocol, you may need to test, document, and gradually optimize different conditions to find what works.

We’ve broken down where to find existing protocols, how to read them, and how to approach building your own in our latest blog.
