How do you normalize data on FRAP?
Sarah Duran 
Normalization that does NOT involve acquisition bleaching correction The FRAP curve is simply normalized by taking pre-bleach fluorescence intensity as 1 and bleach intensity 0.
How do you quantify a FRAP?
Alternatively, FRAP measurements can be quantified simply in terms of the half time of recovery (τ1/2), defined as the time required for a bleach spot to recover half way between initial and steady state fluorescence intensities (6-9).
What is the bleached area in a FRAP?
In FRAP, a specific area of a cell or tissue is photobleached by intense laser light, removing fluorescence from this area. This area is typically a cell membrane or area where diffusion occurs, such as the nucleus, as FRAP requires fluorescent molecules to move around freely in order to function.
What is FRAP analysis?
FRAP (Fluorescence recovery after photobleaching) is used to characterize the mobility of cellular molecules. Several images using a low light level are acquired to determine the initial fluorescence, and then a high level of light for a short time inside a region of interest is applied to bleach the fluorescence.
Does temperature affect FRAP?
For antioxidant capacity determination, oxygen radical absorbance capacity (ORAC) and ferric ion reducing antioxidant power (FRAP) assays were used. The results showed that antioxidant capacity, and phenolic and anthocyanin content all decreased with increasing temperature and drying time.
What do FRAP curves tell us?
In the FRAP curve, the immobile & mobile fraction can be measured by determining the plateau level. A more automatic way of obtaining Half life and mobile/immobile fractions is by “Curve Fitting”. and 1-A is the immobile fraction. Half Life is the time when the recovery is the half of A, by definition.

What is the bleached area in a FRAP fluorescence recovery after photobleaching experiment?
Thanks to the development of GFP fusion proteins, a revival of FRAP applications was seen in the mid-1990s. In FRAP, fluorescent molecules in a region of interest (ROI) within the plasma membrane are bleached by a high-intensity laser source.
