In-Vivo Biology

The In-Vivo Biology department houses a state of the art laboratory animal facility based on clean and dirty corridor concept. Further, the facility is equipped with an airflow system that ensures the supply of clean, HEPA filtered air at specific temperatures and humidity to the animals housed within a room and exhausts all the contaminated air. This is facilitated by the existence of a positive differential pressure maintained between the clean corridor and the animal rooms.

The laboratory animal facility comprises of quarantine, holding, experimental, formulation, necropsy, animal food and bedding material storage rooms and a dedicated washing area with steam sterilizers. The facility is registered for experiments on animals (Registration number: 1964/PO/Rc/S/17/CPCSEA) under the Committee for the Purpose of Control and Supervision of Experiments on Animals (CPCSEA), Ministry of Fisheries, Animal Husbandry & Dairying, Government of India, New Delhi.

Animal experimentation is conducted under the guidance of the Institutional Animal Ethics Committee (IAEC) of Patanjali Research Institute with a license to work on small experimental animals such as mice, rats, rabbits, hamsters and guinea pigs.

The laboratory animal facility is equipped with individually ventilated cages (IVCs) and cage change stations for handling specific pathogen free as well as immunocompromised animals. Further, it possesses well-equipped pharmacology, histopathology and clinical chemistry laboratories. A full time veterinarian along with dedicated scientists and trained animal house technicians are available to provide care to the animals. The facility is under electronic surveillance (CCTV system) and controlled access system for authorized persons, in order to minimize the risk of infection to the animals. Furthermore, the entry to the clean corridor is equipped with an air shower to minimise particulate contamination.

Our highly qualified, experienced scientific team is currently focused in the therapeutic areas of metabolism, inflammation, respiration, nephrology, pain, autoimmunity, hepato-gastroenterology, thyroid, central nervous system, cardiovascular system, wound healing, bone metabolism and thrombocytopenia. So far, we have successfully tested more than 100 Ayurvedic test articles for these therapeutic areas.
