Description
Info: Plant culture preservative and biocide
Product Number: PPM
Storage Conditions: 39ºF / 4º C
PRODUCT DESCRIPTION
Plant Preservation Mixture (PPMTM) is a robust broad-spectrum biocide formulated for use in plant tissue culture. PPMTM targets bacteria and fungi in plant tissue culture growth media as well as contaminated tissue. It affects key enzymes in the Krebs cycle and in the Electron Transport Chain. Depending on the dose and the level of contamination, PPM is a biocidal component in plant culture medium. In addition, it may also function as a bio-static compound as a preventative measure. When
diluted with plant growth media it is effective as a micro-biocide (i.e. bactericide and fungicide) against non-human health pathogenic organisms component of liquid or
semi-solid plant culture media.
PPMTM is effective for most seed baring plants – angiosperm, as well as gymnosperm,- however, it is not recommended for use in ferns, mosses, algae and aquatic plants. Optimization may be required to maximize potency. While PPM is an excellent tool in the prevention and elimination of culture contamination it is not a substitute for
aseptic laboratory techniques and appropriate air handling systems are recommended.
Composition Proprietary
PHYSICAL PROPERTIES
Physical form: Solution

PPM should be added post-autoclave to media containing proteins, prior to dispensing to culture vessels.
PPM at final concentration (diluted in medium) is stable at ambient temperatures for up to 1 month.
PRECAUTIONS
It is a violation of Federal Law to use this product in a manner inconsistent with its labeling. See MSDS for safety, handling, and disposal instructions.
USAGE
The instructions listed below are for general use. Optimization may be required.
| PPM Quick Reference | Maintenance | Sterilization | Agrobacterium |
| Concentration (v/v) | 0.05 – 0.2% | 5.0% (see note) | 0.05 |
| Duration | Continuous | 4 – 12 hours | Continuous |
| Note |
Plant tissue types vary, optimization is required. For freshly isolated protoplast or callus use 0.05% Higher concentrations may result in toxicity or uptake. |
In 3X MS salts (use dry powder formulation from commercial companies) Do not use in combination with other sterilization techniques. Do not adjust pH. Treated tissues should be placed directly into culture medium of choice containing 0.05% PPM. |
May be added to antibiotic cocktail.

PATENT NO. 5,750,402 – The formulation of PPM in tissue culture media at certain concentrations and the use of PPM in tissue culture at certain concentrations to prevent
or eliminate microbial contamination is protected by US patent No. 5,750,402. Patents have been issued in Canada, New Zealand, Australia, the European Community, Israel and other countries. It is also patent pending in many other countries of the world.
