A Siemens gamma camera allows for the capture and analysis of in vivo images.
Additional Equipment
Additional equipment includes a PerkinElmer Optima 5300 inductively-coupled plasma optical emission spectrophotometer, four chemical fume hoods, three laminar flow hoods, an HP 6890 Series GC with HP 7694 headspace sampler, an HP series 1100 HPLC with both UV and radiometric detection, an Agilent series 1200 Infinity HPLC with diode array UV and radiometric detection, an Agilent series 1200 Infinity HPLC with mass spec, variable wavelength UV and radiometric detection and a PerkinElmer Cyclone Plus Phosphor Imager, which provides autoradiography capabilities.
Biological Equipment
We have biological equipment for growing cell lines such as CO2 incubator, -80oC freezer, a certified Biological Safety Cabinet. Additional equipment includes lyophilizer, rotary evaporators, environmental chambers for product studies, steam autoclave, and various microscopes. A 96-well plate washer & reader allow us to efficiently set up ELISA assays and polyacrylamide gel electrophoresis allows for protein characterization.
cGMP facility
The 3600 sq ft cGMP facility encompasses six controlled environment rooms and a large general lab area to assist customers with radiopharmaceutical manufacturing under the FDA guideline 21 CFR 11.
The facility is registered as a manufacturer with the FDA. The facility is equipped with the state-of-art equipment, such as class 5 lead-shielded isolators, laminar flow hoods, fume hoods, HPLC, LC-MS, autoclave, depyrogenation oven, and lyphollizer for making freeze-dried kits.


animal research laboratory
The annex-building that houses our laboratory animals is equipped with a HEPA-filtered cabinet for housing athymic mice along with a PerkinElmer Wizard 3″ 1480 Automatic Gamma Counter to aid in bio-distribution studies. We own a variety of rodent cage types including metabolic cages for mice and rats. IsoTherapeutics is registered with the USDA as a Class R Research Facility under the Animal Welfare Act.
