The following instruments require training
Arcturus XT Micro Dissection System with Nikon Eclipse Ti Microscope
Microgenomic technologies provide the tools necessary to examine expression profiles from samples as limited as a single cell. Laser capture micro-dissection (LCM) is an advanced separation technology that enables the isolation of desired pure cell populations from heterogeneous tissue samples. LCM utilizes an infrared laser pulse system which adheres cells of interest to a transparent thermoplastic film, preserving essential cellular and morphological characteristics, while maintaining the integrity of biomolecules such as DNA, RNA, and proteins. UV laser cutting may also be utilized in conjunction with LCM allowing for the rapid isolation of larger populations of cells.
Laser capture (5-10 micron section) UV cutting laser (up to 50 micron thickness) Isolate cells for DNA/RNA and Protein extraction.

ECHO MRI 700 BODY COMPOSITION ANALYZER
EchoMRI-700 Whole Body Analyzer – The EchoMRI™700 Analyzer deliver precise body composition measurements of fat, lean, free water, and total water masses in live animals weighing up to 700 grams respectively. Small Animals – mice, rats, hamsters, within the weight range.
Scanning takes 0.5 – 3.2 minutes, depending on the precision options.
The live animals need no anesthesia and no special preparation before measurement. Approved animal protocols are necessary prior to use.
EchoMRI™ Analyzers are exceedingly easy to operate. A training period of one hour is sufficient for individuals without prior knowledge.
Numeric results are stored and can be viewed again later at any time, as well as extracted either into Excel and ASCII files or into Access database.
The EchoMRI 700 Analyzers are stand-alone units, on 4 casters for easy relocation. They use standard power sources, and are completely shielded and safe to run.

PARAFFIN WAX HISTOLOGY EQUIPMENT
Paraffin Infiltration, Embedding and Sectioning
Paraffin embedding is used to prepare the tissue specimen so it does not shred upon slicing. The tissue specimen is infused with paraffin (wax) and placed within a mold to which more melted paraffin is added. The result is a small cube of wax with the paraffin-filled tissue specimen within it. Tissue embedding is routinely used to prepare tissue biopsies for examination.
The tissue embedding process involves several steps.
1. Infiltration – STP 120 (replaced the pictured item on a table beside the Embedding system
2 Embedding – Histostar 4
3. Sectioning – Finesse Rotary Microtome, water bath and slide warmer
A protocol is necessary for this step of tissue processing. The process includes fixation, dehydration, clearing agents and paraffin wax. In some cases fixation is performed prior and the process starts with dehydration. Type of tissue and downstream applications determine protocol.
- A programmable, carousel tissue processor
- Tissue samples are placed in cassettes which are placed in an organizer tissue basket
- The tissue basket is placed on the operating head assembly which lowers into the containers below.
- There are 7 reagent (alcohols or fixative) containers, 3 metal clearing agents (Citrosolv is used in core only), and 2 wax baths.
- Located in PSC 863/841 under the hood in front of the HistoStar 4
- Rotary Microtome, water bath and slide warmer are in PSC 920
