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, PPMā„¢ (Plant Preservative Mixture), is a broad-spectrum biocide/fungicide for plant tissue culture. PPMā„¢ (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, PPMā„¢, 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. PPMā„¢ prevents the germination of both bacteria and fungi spores. Because it's heat stable, it can be autoclaved with media. PPMā„¢ 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.

What started as what may seem as slow growth can quickly become rapid multiplication in plant tissue culture and it can be such a mesmerizing process.

If learning plant tissue culture has been in the back of your mind, this is your sign to learn it.

Our next master classes are now open, comment CLASSES and we’ll send you the link to learn more and save your seat 🧫

Every explant sterilization protocol is a tradeoff. Push the bleach too hard and the tissue browns. Go too gentle and you are culturing bacteria on purpose.

Most people find their way to a working sequence by burning through material until something sticks. That takes months and a lot of dead explants.

Francisco Palacios, our Lab Director, is spending an hour on how he sets that dial in the PCT lab. Free, live on Zoom.

He is covering source material selection, sterilization agents and contact times, why surface sterilization does not touch endogenous contamination, where PPMā„¢ belongs in the workflow, and how to read a contaminated vessel so you can trace the source.

Coupled with proper observation of aseptic laboratory techniques, PPMā„¢ can increase your chances of a successful and thriving tissue cultures!

PPMā„¢ prevents the germination of both bacteria and fungi spores. It is heat stable and therefore can be autoclaved with the media.

PPMā„¢ can be, and should be used as a standard ingredient in plant tissue culture media, and is also substantially less expensive than commonly used antibiotics.

While PPMā„¢ was principally designed to inhibit airborne contamination, waterborne contamination, and contamination introduced from human contact, it can also — in many cases — be used to reduce endogenous contamination.

PPMā„¢ does not affect the genetic profile of the plants.

What most culturists skip after witnessing these is that the symptom tells you where your process went wrong.

Save this one for later.

A lot of people meet tissue culture at Stage 2, the jar full of shoots. That's the part everyone photographs. It's also the part that fails when the stages on either side of it get rushed.

A few things worth knowing:

Stage 0 does more work than it gets credit for. Most contamination rides in on the mother plant rather than starting in your hood. Stock that's been grown clean, kept dry, and actively growing for a few weeks before you cut will give you a much easier time at initiation.

Stage 1 is not measured in growth. If your explant is alive and clean after two weeks, that stage did its job. Save your expectations for multiplication.

Stage 4 is where good work gets lost. Plantlets raised in a sealed vessel at near saturation develop thin cuticles and stomata that are slow to close, so they can't hold water yet. Put them straight into room air and a perfect batch can dehydrate in an afternoon. Bring the humidity down over days.

Five stages, five different jobs. Skip one and you usually pay for it two stages later.

Which stage has cost you the most cultures? šŸ‘‡
