PLANT CELL TECHNOLOGY PLANT PRESERVATIVE MIXTURE PPM
Plant Preservative Mixture (PPM) 100 Ml. Plant Preservative Mixture (PPM), is a broad-spectrum biocide/fungicide for plant tissue culture. PPM™ is the ultimate solution to the never-ending struggle against microbial airborne, waterborne and endogenous contamination. 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 reservative/Biocide, yet does not impair in vitro seed germination, callus proliferation and callus regeneration.Despite the most stringent use of sterile techniques, the contamination of plant cell and plant tissue cultures remain a persistent problem that can result in losses ranging from small number of cultures to the loss of whole batches.PPM™ prevents the germination of both bacteria and fungi spores. It is heat stable and therefore can be autoclaved with the media.
