Thermo Fisher Scientific Improves Workflow in HLA Laboratories with 10-Second Analysis of DNA Microsamples using NanoDrop 1000

WASHINGTON, D.C. (July 29, 2008) - Thermo Fisher Scientific Inc., the world leader in serving science, will exhibit a new spectrophotometer that offers unique benefits for human leukocyte antigen (HLA) typing laboratories dealing with donor tissue matching. The Thermo Scientific NanoDrop 1000 represents the growing trend of successful genome research tools finding their way to the clinical research setting. Specifically, the NanoDrop 1000 is utilized in the workflow as a replacement to time-consuming traditional spectrophotometers where efficiency and time-to-result are critical.

The NanoDrop 1000 is capable of carrying out full UV-Vis absorbance measurements with only 1 ul of undiluted sample, enabling HLA laboratories to significantly speed up analysis time. The NanoDrop 1000 has been integrated into tissue typing workflows through a validation process as set by the HLA typing community. The NanoDrop 1000 spectrophotometer will be showcased for the first time at the Thermo Scientific booth 2739 at AACC 2008, being held in Washington D.C., from July 29 - 31.

This innovative cuvetteless method enables HLA laboratories to quickly and effectively process DNA samples without compromising yield. HLA is the major histocompatibility complex in humans, and laboratories performing HLA typing have distinct requirements for instrumentation, including preserving sample yield and optimizing analysis time. The NanoDrop 1000 spectrophotometer has been successfully integrated into the HLA typing workflow in a number of leading laboratories. DNA is extracted and purified from donor tissue and quantified on the NanoDrop 1000 using a patented sample retention system requiring only 1 ul of sample. This quantitation method enables HLA laboratories to quickly and effectively process DNA samples without compromising yield.

In many HLA cases, donor workup results are required in less than four hours as the speed and accuracy of tissue analysis can affect the long-term graft survival of the tissue. The NanoDrop 1000 spectrophotometer allows laboratories to analyze microsamples of DNA in only 10 seconds, reducing labor time and increasing laboratory productivity. Additionally, the novel microsample quantitation technology of the NanoDrop 1000 is critical for typing samples of limited cell mass, such as mononucleated bone marrow specimens.

In addition to reducing spectrophotometric quantitation prior to DNA amplification, the NanoDrop 1000 enables HLA typing laboratories to comply with the strict standards set by the ASHI. The NanoDrop 1000 has passed the rigorous validation process for HLA laboratories across the United States, and is now recommended by many certified laboratory inspectors.
