At the Atlanta Centers for Disease Control, researchers have detected about 100 attograms (0.0001 picograms
) of 2,3,7,8-TCDD in human serum samples.
Activity measurement for deoxyribonucleases I and II with picogram
sensitivity based on DNA/SYBR Green I fluorescence.
In a report submitted to agency chief Kayoko Shimizu, the Central Environment Council also suggested that limits on dioxin concentration in soil and water be set at 1,000 picograms
per gram and 1 picogram
per liter, respectively.
Based on the viral load as detected by RLIJ, women were stratified into four groups, ranging from a low viral load of 1-10 RLU per picogram
to more than 1,000 RLU per picogram
in the cohort of women with the highest viral load.
Agreat number of laboratory instruments perform highly reliable analyses, down to the picogram
level, on 8 to 200 l of specimen --and often on less.
The ThruPLEX-FD Prep Kits are designed for use with the next-generation sequencing (NGS) platforms of US Illumina Inc (NASDAQ:ILMN) to streamline library preparation for fragmented DNA/cDNA and reduce sample input amounts to picogram
The HGA 900 graphite furnace for proprietary AAnalyst 400 atomic absorption spectroscopy instruments is controlled by WinLab32 software, which offers advantages for trace metal analysis, including detection limits in the picogram
range, low microliter-level sample consumption and freedom from interferences.
Average measurements taken at the 14 survey sites, which were concentrated in the prefectures of Osaka, Saitama, Chiba and Tokyo, exceeded the prescribed level of 0.8 picogram
per cubic meter of air.
The system is capable of detecting picogram
to nanogram levels of most chemicals.
The dose is simply a picogram
TEQ per day quantity taken in by the infant, which is determined externally; the model requires only the picogram
TEQ per day input.
Reproducible quantitative and linear results are routinely achieved at picogram
