Training and Consultations

The Histology Core is pleased to offer virtual training for self-service users. Virtual training is available for:

  • Paraffin Microtome – Basic Operation and Safety
  • Cryostat Microtome – Basic Operation and Safety
  • Cryofilm Sectioning

If you are interested in receiving training, please email the Core Technical Director, Dr Edgardo Arroro. He will email you a link to the training video. After watching the video, email Dr Arroyo to arrange a phone call to review key training aspects, including safety. He will then provide you with calendar access so you can sign up and use the equipment. Note that standard training fees still apply.

Full Service Histology

Please fill in the PROJECT REQUEST FORM. Ensure all required fields are completed. Project Description should include a 1-2 sentence description of the scientific goals of the project, the tissue type and species. Email the electronic copy to Dr Arroyo, and bring your samples along with the completed request form to the core.

For tissue processing requests only, leave the paper copy and samples on top of the tissue processor in the hallway, and notify Dr Arroyo. Please DO NOT leave samples with no name or paperwork as this will delay processing. Please don't hesitate to contact us with any questions
