一般說明
Drug Metabolism (DM) Pharmacokinetic (PK) studies provide crucial insight into the way drug candidates behave in the body. These studies are a critical step in drug development.
QIAcard™ FTA™ DMPK Cards for Drug Metabolism Pharmacokinetics enable microvolume sampling with only 10 to 20 µl per sample and are designed for use with blood samples. The cards can also be used with colorless samples such as plasma, cerebrospinal fluid and urine.
QIAcard™ FTA™ DMPK-A contains impregnated chemicals enabling protein denaturation to inactivate endogenous enzymes. Cell lysis releases endogenous cellular materials onto card. Stabilization of DNA allows resampling of blood spot for pharmacogenomics. Impregnated chemicals may interfere with mass spectrometry detection e.g. ion suppression.

特點和優勢
- DBS microvolume sampling requires only 10—20 μl per sample.
- Consistent data are obtained through more serial sampling from individual animals.
- Less reliance on composite data.
- The 3-step DBS procedure is more straightforward than the cumbersome centrifugation, isolation and clean-up of plasma.
- Conveys greater analyte stability through on-substrate clean-up, especially for enzyme-sensitive compounds.
- Room temperature stability saves on cost of dry ice shipments and allows remote sampling.
其他說明
Analysis is primarily with HPLC or UHPLC followed by MS/MS detection, direct desorption MS techniques such as DESI. Methanol or aqueous/organic mixtures have been shown to work well for small molecules and aqueous buffers are recommended for proteins. Select a good solvent for the analyte while maintaining compatibility with the HPLC conditions to be used. The choice of DMPK card depends on many factors such as the analyte chemical structure, extraction solvent and analysis workflow.
