How To Use A Threshold To Reduce Background Noise In Flow Cytometry

Getting a clear signal with reduced noise is an essential component to good data. Adding a threshold when acquiring flow cytometry data is one way to do that. It reduces the number of events by setting a bar that a signal pulse must clear before it is counted as an event. Depending on the importance of the data, the downstream applications for the data (or sorted cells) will dictate how critical the threshold is. In combination with proper sample preparation, appropriate thresholding will reduce debris and ensure best outcome.

How Flow Cytometry Converts Photons To Digital Data

Flow Cytometry conversion of photons to electrons
Pin It

From photon, through conversion from light, into an electron, into an electronic signal pulse. The journey of a photon, through to its data representation via flow cytometry, involves the detection system and the electronics, and basically following a bouncing photon to its ultimate digitization. This article provides 3 key takeaways in the process from photons through to end data for analysis.

T cell differentiation and effector function regulation is an area that needs to be better understood. Until then, speculation combined with best practices help you determine your T cell population’s status. Functional profiling is the primary determinant with surface markers as supporting evidence to assess whether your T cell is activated, resting, or naïve. Here are ways to help differentiate your T cells.
