Priority of Access
Preference in scheduling services is given to UACC Members and Investigators with peer reviewed and competitively funded grants, to UA Investigators and then to external entities.
All biological materials are potential biohazards, some more than others.
As a courtesy, please include relevant information about potential biohazardous samples or conditions on the Request Form.
Notify the lab staff if your samples present any undue biological hazard.
TACMASR does not accept
- Radiolabeled material
- Fresh material with known infectious agents (AIDs, hepatitis, etc)
- Fresh tissue without making prior arrangements with staff
- Cell pellets on Fridays without prior arrangements
TACMASR is equipped with technology and reagents to perform routine histology including: TissueTek tissue processor, embedding station, two rotary microtomes, Microm HM550 cryostat, a Benchtop Solvent Recycler (CBG Biotech) and refrigerators/freezers.
Tissue specimens are handled in a ThermoScientific Shandon Tissue Grossing Station. Blood and urine are centrifuged in a Sorvall Legend RT Refrigerated Benchtop centrifuge and aliquotted in a NuAire Biological Safety Cabinet Class II Type A/B3. A Shandon Cytospin 2 is used to prepare cytospin cell preps. Two rolling carts containing equipment and supplies to fix and snap freeze tissue are available. Frozen biospecimens are stored in four -80°C freezers located in the basement of the Salmon Building. This room is equipped with backup emergency power and an emergency alarm system which is monitored by UA Facilities Management.
The majority of IHC assays are performed on the Discovery XT Automated Staining platform for IHC and ISH (Ventana Medical Systems, Inc, Tucson, Ariz.). Equipment for manual staining immunostaining is also available.
[NOTE: currently not working] The Arcturus VeritasTM Laser Capture Laser Microdissection instrument is available for use by investigators. TACMASR provides technical support to prepare samples for LCM and trains users to harvest RNA, DNA and protein by LCM to address issues of tissue heterogeneity. A Qiagen BioRobot EZ1 for harvesting DNA from blood samples is also available.
Photomicrography and molecular imaging equipment includes:
