Analyzing the Results
The Venor Gem kit provides a clear, straightforward way to analyze your results. A key element is understanding the visual presentation of the results. The kit often employs colorimetric or fluorescent assays, with specific color changes or fluorescence intensities correlating with the presence or absence of mycoplasma. Carefully examining the color intensity or fluorescence signal on the provided assay plate or instrument readout is essential.
Quantitative measurements, when available, allow for a more nuanced assessment.
Interpreting the Results
Interpreting results hinges on established criteria. These criteria are usually provided in the kit’s instructions, which should be meticulously followed. Compare the observed readings to the positive and negative controls included in the kit. Deviation from the expected values for these controls necessitates further investigation. Consistency is key: a consistent pattern across multiple samples points towards a significant finding.
Identifying Mycoplasma Contamination
Identifying mycoplasma contamination is a matter of careful comparison. A positive result, typically indicated by a color change or fluorescence signal exceeding the threshold values, suggests the presence of mycoplasma. Conversely, a negative result, usually within the expected range, indicates no detectable mycoplasma. Results should be evaluated within the context of the entire experimental setup and previous observations.
It is vital to consider any potential confounding factors or experimental errors that might affect the results.
Examples of Different Results and Interpretations
Let’s illustrate with examples. A strong positive signal, exceeding the positive control by a substantial margin, strongly suggests a significant mycoplasma contamination. A result close to the negative control, but not exceeding the threshold, might indicate a low level of contamination or a false positive. A result matching the negative control suggests no detectable mycoplasma.
