Using a real-time PCR assay, which requires a considerably low quantity of biological samples, we estimated telomere length in a large number of CRCs and in corresponding adjacent non-cancerous mucosa.
These findings could be related to a low quantity of EV in the sample, which can be detected by using real-time PCR but not by PCR-based VP1 sequencing.
However, due to the low quantity of parasites present in biological samples, DNA markers with high copy number like kinetoplast minicircles are needed.
Using a nanostring device, which digitally quantifies a wide set of mRNA transcripts starting from a very low quantity of tissue, we analysed RNA samples obtained from DRGs of mice which received intrathecal injections of 10 pmol of miRNA-1a-3p inhibitor or mismatch inhibitor in vivo every 24 h with in vivo transfection reagent from PID-4 to PID-9.
In the present study, for the first time, a new extraction method based on "ultrasound assisted microextraction-nanomaterial solid phase dispersion (UAME-NMSPD)" was developed to preconcentrate the low quantity of thymol and carvacrol in pharmaceutical samples prior to their HPLC-UV separation/determination.
This assay offers various advantages, including (1) the small quantities of samples required for detection and a low level of reagent consumption, (2) multiplex detection, (3) flexibility in combining the capture and detection strategies, and (4) higher throughput.
The MID is the lowest quantity of the sample required to inhibit any visible growth.
Thus, it is likely that the 24-mix sample contains very low quantity of viral particles for the 3 strains that failed sequencing process.
HRM is a suitable methodology to test FFPE samples as well as samples with a very low quantity of DNA.
The single Brucella positive spleen sample had a high ct value suggesting a low quantity of DNA within the tissue; follow up attempts to culture Brucella from the splenic tissue of this animal were unsuccessful.
