Plant Cell Technology. develops, produces and markets innovative solutions for commercial and research plant tissue culture laboratories and plant breeders. Its flagship product, PPM™ (Plant Preservative Mixture), is a broad spectrum biocide/fungicide for plant tissue culture. PPM™ is the ultimate solution for permanent control of atmospheric, water and endogenous microbial contamination.

PPM™ (Plant Preservative Mixture) is a heat-stable preservative/biocide that, depending on dosage, effectively prevents or reduces microbial contamination in plant tissue culture. At optimal doses, PPM™ does not impair in vitro seed germination, callus proliferation or callus regeneration.

Despite the stricter use of sterile techniques and aseptic conditions, contamination of plant cell and tissue cultures remains a persistent problem. PPM™ prevents the germination of bacterial and fungal spores. As it is heat stable, it can be autoclaved with the medium. PPM™ can be used as a standard ingredient in plant tissue culture media. PPM is less expensive than antibiotics and can simultaneously prevent fungal contamination. PPM is biostatic and biocidal. In addition to inhibiting contamination from air, water and human contact, it can also be used to reduce endogenous contamination.

Plant Cell Technology is owned and managed by its President, Martin Kalin. PCT’s lead scientist involved in the development of the PPM™ application is Dr Assaf Guri, who holds degrees in genetics, applied genetics and plant breeding from the Hebrew University of Jerusalem and Michigan State University in the USA. Plant Cell Technology has numerous distributors located in South America, Europe, Asia and the Middle East. Its headquarters are located at 1823 Jefferson Pl. NW, Washington D.C.

PCT has been a leading organisation in the plant tissue culture industry since 1995.
We develop, produce and market innovative solutions for plant tissue culture operations worldwide. Our well engineered, certified and reliable products keep your crops healthy and free from contamination.

Our mission is to provide world-class products and services to tissue growers of all sizes and experience and to increase access to innovative and effective tissue culture solutions.
Quality is at the heart of everything we do and, because of this value, we have earned the trust of thousands of laboratories and organisations working in the tissue culture field.

Plant Cell Technology’s flagship product, PPM, is essential to the success of any plant tissue culture and we have been proud to supply it to growers, laboratories and distributors around the world for almost three decades. While our product line has evolved since the invention of PPM, our mission remains the same.
