Overview

Cytogenex provides a fast and flexible Analytical and Research service using internationally accepted and validated methodologies. These activities allow for testing in the following categories:

  • Pharmaceutical/Nutraceutical/Food Supplement
  • Food analysis
  • Environmental monitoring
  • Stability
  • Anti-microbial activities of disinfectants/preservatives
  • Bio-Medical Research and Development

In addition to the above and to the provision of a trouble-shooting consultancy, Cytogenex also provides a consultancy service for the testing of pre-launch products for the food preparation and kitchen appliance industries.


Pharmaceutical/Nutraceutical/Food Supplement

Licensed and non-licensed products are analyzed for microbial contaminants using Methodologies approved by the MHRA. Results are presented to the customer by way of a Cytogenex Microbiology Report Form in a time period agreed with the customer.

Product identity, in the case of natural products, is addressed using in-house-developed DNA recognition techniques. Some of these techniques have been developed at the specific request of companies such as, Mycology Research Laboratories.

Other potential contaminants/active principals can be determined by in-house techniques, such as ELISA (Aflatoxin) and high performance thin layer chromatography and by HPLC/GC-MS/ ICP-MS and ICP spectrograph, provided in collaboration with the University of Hull as part of a pre-arranged project.


Food Analysis

Using principals developed under the guidelines of EU GMP for Pharmaceutical raw materials and products, microbiological analysis can performed for food products using methodologies provided by the customer. These methodologies are performed under the Accredited Quality Management System developed by Cytogenex. Allergens can be determined by methodologies involving antibody recognition (ELISA) and common genetic modifications can be screened using DNA techniques.


Environment Analysis

Microbial contamination of environmental samples can be performed using technologies available within the laboratory and the specific detection of pathogens can be performed using DNA techniques.

Cytogenex has developed an expertise for the detection of fungal agents, such as the Dry Rot fungus, Serpula lacrymans, using the technique of DNA-polymerase chain reaction (DNA-PCR). In instances of wood rot, it can sometimes be difficult to accurately identify the extent and spread of the Dry Rot fungus in a building environment. Cytogenex can provide an analysis of a small amount of material (less than 1g wood etc.) within 3 days of receipt of the sample.


Stability Monitoring

For the Pharmaceutical/Food/Healthcare and Cosmetics industries, it is important to obtain data concerning the length of time a product can be maintained at a normal shelf temperature before significant microbiological spoilage occurs. Cytogenex is able to perform stability studies at the temperature and relative humidity as instructed by the customer.


Anti-microbial Activities of Disinfectants/Preservatives

The ability of surface-acting and immersion-dependent disinfectants to adequately prevent the growth of microbial agents can be tested using methodologies that conform to international standards. Cytogenex has been working with companies, such as BioD Ltd., to develop Eco-friendly disinfecting agents for use in both domestic and industrial environments.


Bio-Medical Research and Development

Over the years that Cytogenex has been operating, the Company has maintained an interest in novel health-care-related therapeutic approaches. A number of projects have been undertaken and some of these have resulted in significant international publications:
