Scientific Services

With cutting edge technologies in scientific research along with wide range of experienced professionals, CPT alliances with its partners to bring forth endless variety of disease models and preclinical services in the following areas

  • Pharmaceuticals
  • Medical devices
  • Agrochemicals and Pesticides
  • Food products and Nutraceuticals
  • Folklore Remedies

Pharmacokinetics by various routes viz., oral, intravenous and subcutaneous in mouse models in (SAM, Balb/C), rats (Wistar, Sprague Dawley)

  • Tissue Distribution
  • Brain to Plasma Ratio

CPT have validated animal models on

  • Alzheimer's and Parkinson's disease (Chemical and ICV surgical model)
  • Cerebral stroke (middle cerebral artery, 2/4 vessels occlusion surgical models)
  • Depression (Chemical and behavioral CUMS models)
  • Epilepsy (Chemical and ICV surgical models)
  • Gastric ulcer (Surgical, chemical models)
  • Diabetes (Chemical, diet and genetic models)
  • Hepatic diseases (Drugs and chemical models)
  • Pain and Inflammation models (carrageenan, cotton pellet granuloma, formalin and acetic acid models) )
  • Nootropics (radial arm maze, passive avoidance, transfer latency)
  • Rheumatoid arthritis (FCA model)

Toxicology is a highly eclectic branch of medical science that deals with study of toxic / adverse effects of chemicals, biologics in living systems. This branch of science serves the society in many ways by not restricting to protect humans and the environment from the deleterious effects of toxicants but also to facilitate the development of newer drugs. CPT is approved (license no: 155/PO/Re/S/1999/CPCSEA) by Committee for Control and Supervision of Experiments on Animals (CCSEA), Ministry of Environment and Forests, Government of India, to conduct experiments on animals (rodents, guinea pigs, rabbits)

Test Systems

  • Histopathology and Immunohistochemistry

    Fixing, trimming, embedding, sectioning and staining tissues. Special requirements with selective staining or immunohistochemical also performed

  • Biochemical assays

    ELISA and fluorescence assays, inflammatory markers, cell membrane markers, oxidative stress markers and anti-oxidant proteins such as superoxide dismutase, catalase, glutathione, etc.
