美国Plant Cell Technology公司为商业及研究用植物组织培养实验室和植物种植者开发、生产了旗舰产品PPM™ (Plant Preservative Mixture)，它是一种广谱抗微生物剂，可以杀死细菌和真菌细胞，防止真菌孢子的萌发，并在较高浓度下能消除内源性污染的外植体。研究表明PPM™活性成分可以渗透过真菌或细菌细胞壁，抑制柠檬酸循环和电子传递链等中心代谢循环中的关键酶的活性，并且可以抑制培养基中的单糖和氨基酸向真菌和细菌细胞的运输。PPM™能有效地抑制植物细胞和植物组织培养中的通过空气、水、人传播的微生物污染及内源性污染，而不会影响体外种子发芽、愈伤组织增殖和愈伤组织的再生。并且，PPM™具有热稳定性，可以和培养基一起灭菌，同时比常用抗生素价更低廉，可以作为植物组织培养基的标准成分。

The principal PCT scientist involved in the development of the PPM™ application is Dr. Assaf Guri. Dr. Assaf Guri holds degrees in genetics, applied genetics and plant breeding from the Hebrew University in Jerusalem and Michigan State University in the US. Before joining Plant Cell Technology, Inc., Dr. Guri worked with the Volcani Agricultural Research Center in Israel, Michigan State University in East Lansing, Michigan and DNAP in New Jersey.

TiterMax®佐剂被用于增强免疫反应。TiterMax®佐剂有着跟弗氏佐剂相同的功效，但具有更安全、更易用的特点，是弗氏佐剂的理想代替产品。

TiterMax® adjuvants are used to produce cell mediated and humoral responses in research animals. TiterMax® adjuvants were developed to meet the specific needs of investigators for immunoadjuvants that are at least as effective as Freund's Complete Adjuvant, safer and easier to use. They are an attractive alternative to Freund's Complete Adjuvant for use by researchers in inducing antibody to diverse antigens. The key to the potency of TiterMax® adjuvants lies both in the immunostimulatory activity of their components and in the fact that they form a stable water-in-oil emulsion. TiterMax® adjuvants contain three essential ingredients: Proprietary block copolymers, squalene, a metabolizable oil, and a unique microparticulate stabilizer. Like Freund's Complete Adjuvant, TiterMax® adjuvants can be used with a wide variety of antigens because they can entrap any antigen in a water-in-oil emulsion. TiterMax® adjuvants aid in the antigens effective presentation to the immune system without the toxic effects of Freund's Complete Adjuvant.
