Real Time RT-PCR02:57

Real Time RT-PCR

65.3K
Real-time reverse transcription-polymerase chain reaction, or Real-time RT-PCR, is an analytical tool used to determine the expression level of target genes. The method involves converting mRNA to complementary DNA with the help of an enzyme known as reverse transcriptase, followed by the PCR amplification of the cDNA. These two processes can be performed simultaneously in a single tube or separately as a two-step reaction.
The real-time quantification of the number of amplified products is...

Detection of Gross Error: The Q Test

7.0K
When one or more data points appear far from the rest of the data, there is a need to determine whether they are outliers and whether they should be eliminated from the data set to ensure an accurate representation of the measured value. In many cases, outliers arise from gross errors (or human errors) and do not accurately reflect the underlying phenomenon. In some cases, however, these apparent outliers reflect true phenomenological differences. In these cases, we can use statistical methods...

Detection of Black Holes

2.6K
Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s.
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.
Not until the 1960s, when the first neutron...

Difference from Background: Limit of Detection

8.4K
The limit of detection (LOD) is the smallest amount of analyte that can be distinguished from the background noise. The LOD value corresponds to the concentration at which the analyte signal is three times larger than the standard deviation of the blank signal. Below this value, the analyte signal cannot be differentiated from the background noise. It is calculated by dividing the calibration slope by 3 times the standard deviation of the blank signals.
The LOD indicates the presence or absence...

Effects of EDTA on End-Point Detection Methods

667
Different methods, such as visual observance of metal-ion indicators, spectroscopic techniques, and potentiometric methods, can determine the endpoint of an EDTA titration.
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...

    Summary

    A new method using fluorescent V(D)J recombination assay/polymerase chain reaction (FVA/PCR) can detect Cryptosporidium oocysts in beverages. This sensitive, rapid, and easy technique identifies as few as 1.0 oocyst/ml within 6 hours.

    Area of Science:

    • Microbiology
    • Parasitology
    • Molecular Biology

    Context:

    • Food and beverage safety is crucial.
    • Accurate detection of waterborne parasites like Cryptosporidium is essential.
    • Existing detection methods can be time-consuming or lack sensitivity.

    Purpose:

    • To evaluate the efficacy of a fluorescent V(D)J recombination assay/polymerase chain reaction (FVA/PCR) protocol for detecting Cryptosporidium oocysts in beverages.
    • To determine the sensitivity and speed of the FVA/PCR method for parasite detection.

    Summary:

    • An established FVA/PCR protocol was successfully applied to detect Cryptosporidium oocysts spiked in beverage samples.
    • The method demonstrated high sensitivity, detecting as low as 1.0 oocyst/ml.
    • Detection was achieved within a 6-hour timeframe, highlighting its speed.
