Our Patented amasse™ Device


Dried bio-fluid specimen (DBS) collection ...

has been used as a micro-sampling technique for QUALITATIVE capillary blood testing since the 1960’s (e.g., neonatal screening).

Now, with the advent of the new OpAns’ patented amasse™ collection device, DBS can be used to streamline QUANTITATIVE bio-fluids testing (e.g., capillary blood) using state-of-the-art analytical techniques like mass spectrometry with chromatographic separations.

Avantages include reduction in pain and anxiety associated with venipuncture; reduction in processing, handling and shipping requirements resulting in reduction in costs.

Selection from Our Portfolio ...

We developed and validated novel analytical methods, and analyzed specimens in support of the following:


...

Steroid hormones were quantified using high-performance liquid chromatography followed by tandem mass spectrometry (HPLC-MS/MS).  Detection limits varied depending upon analyte.   Media samples were extracted using methyl tert-butyl ether (MTBE); derivatization with dansyl chloride was required for estrone and estradiol.

...

Test articles were incubated in Liver S9 fractions at 37 °C.   Samples were pulled from the incubation mixture at specified time points (0 to 90 minutes) and added to a solution of 1% ammonium hydroxide in N-propyl alcohol.   The amount of test article in each sample was quantified by HPLC-MS/MS.

...

Trimethoprim (TMP) and sulfamethoxazole (SMX) concentrations were quantified using validated liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) assays.   The TMP validation range for the assay was 25 to 50,000 ng/mL.   The SMX validation range for the assay was 250 to 500,000 ng/mL.
