About Plant Preservative Mixture (PPM™)
PPM™ is a heat stable preservative/biocide which can be used to effectively prevent or reduces microbial contamination in plant tissue culture.
- At optimum doses, PPM™, which stands for Plant Preservative Mixture™, is an extremely effective Preservative/Biocide, yet does not impair in vitro seed germination, callus proliferation and callus regeneration.
- PPM™ prevents the germination of both bacteria and fungi spores. It is heat stable and therefore can be autoclaved with the media.
- PPM™ 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.

PPM
I am very grateful to have found PPM. In the past I was averaging a 70% contamination rate. Since using PPM I'm holding steady at a 5% contamination rate.

Works Perfectly!
I'm new to micropropagation. I was concerned about contaminated cultures. I've use PPM in the first several media batches and all have been contamination-free. For me, PPM is a required ingredient in a media formulation.

Makes a difference in home culture lab
I am a beginner hobbyist in tissue culture, still experimenting to get reliable results. There is a notable improvement in contamination rates when using PPM. I recommend it and will continue to use it in my culture medium.

PPM
Had fungal growth in my latest batch of water-germinated VFT seeds. After rinsing the seeds w/0.5% bleach and then plating it into MS+PPM, they germinated without any contaminants. PPM works.

PPM is an integral part of my business
We use PPM everyday in our business’s tissue culture division. A high throughput approach is capped off by PPM cementing the successes and helping convert them to profit. Thanks.

Fast and Easy
Quick shipping and amazing customer service as well as competitive pricing. Highly recommended to anyone looking to reduce the contamination possibilities. Opened up my package and they even tossed in a free shirt, only thing I wish is that it would have been a little bigger size so I could rep it out and about.

First time user
Have used another companies ppm and excited to try out this one from other reviews. Got to me super quick and was securely shipped with no damage.

Plant Preservative Mixture (PPM) 30 ml
Adding the recommended amount of heat-stable PPM (2 ml per liter of orchid germination medium) provides assurance that small lots of imported orchid seed received under the USDA APHIS 587 program are more likely to be sown successfully without competing, destructive contamination.
