Abstract:
Fluorescence recovery after photobleaching (FRAP) has been useful in delineating cardiac myofilament biology, and innovations in fluorophore chemistry have expanded the array of microscopic assays used. However, one assumption in FRAP is the irreversible photobleaching of fluorescent proteins after laser excitation. Here we demonstrate reversible photobleaching regarding the photoconvertible fluorescent protein mEos3.2. We used CRISPR/Cas9 genome editing in human induced pluripotent stem cells (hiPSCs) to knock-in mEos3.2 into the COOH terminus of titin to visualize sarcomeric titin incorporat

Abstract:
Fluorescent recovery from photobleaching coupled with confocal microscopy was explored as a potential high-resolution method of imaging the distribution of enzyme activity in single living cardiac myocytes without relying on steady state measurements of fluorescence. On a fundamental level, much remains to be determined regarding how local conditions within a cell affect metabolism. Many studies have suggested that energy metabolism in muscle cells cannot be accurately described assuming a homogenous system of enzymatic reactions [1,2]. The autofluorescence of NADH has been used in many studie

Purpose Vitreous humor is a complex biofluid whose composition determines its structure and function. Vitreous viscosity will affect the delivery, distribution, and half-life of intraocular drugs, and key physiological molecules. The central pig vitreous is thought to closely match human vitreous viscosity. Diffusion is inversely related to viscosity, and diffusion is of fundamental importance for all biochemical reactions.

Abstract:
Fluorescence recovery after photobleaching (FRAP) is a widely used tool for estimating mobility parameters of fluorescently tagged molecules in cells. Despite the widespread use of confocal laser scanning microscopes (CLSMs) to perform photobleaching experiments, quantitative data analysis has been limited by lack of appropriate practical models. Here, we present a new approximate FRAP model for use on any standard CLSM. The main novelty of the method is that it takes into account diffusion of highly mobile molecules during the bleach phase. In fact, we show that by the time the first postblea

AbstractFluorescence recovery after photobleaching (FRAP) is a versatile tool for determining diffusion and interaction/binding properties in biological and material sciences. An understanding of the mechanisms controlling the diffusion requires a deep understanding of structure–interaction–diffusion relationships. In cell biology, for instance, this applies to the movement of proteins and lipids in the plasma membrane, cytoplasm and nucleus. In industrial applications related to pharmaceutics, foods, textiles, hygiene products and cosmetics, the diffusion of solutes and solvent molecules cont

Abstract:
To account for the many functions of phosphatidylinositol 4,5-bisphosphate (PIP2), several investigators have proposed that there are separate pools of PIP2 in the plasma membrane. Recent experiments show the surface concentration of PIP2 is indeed enhanced in regions where phagocytosis, exocytosis, and cell division occurs. Kinases that produce PIP2 are also concentrated in these regions. However, how is the PIP2 produced by these kinases prevented from diffusing rapidly away? First, proteins could act as “fences” around the perimeter of these regions. Second, some factor could markedly decre

One recent hypothesis for the mechanism of chromosome movement during mitosis predicts that a continual, uniform, poleward flow or "treadmilling" of microtubules occurs within the half-spindle between the chromosomes and the poles during mitosis (Margolis, R.

Abstract Fluorescence recovery after photobleaching (FRAP), or fluorescence photobleaching recovery (FPR), describes a family of related techniques that measure transport properties of fluorescently labeled molecules. This is done by monitoring the evolution of a fluorescence signal after a spatially localized population of fluorophores is bleached by light. The classical FRAP experiment with one-photon excitation uses a focused laser beam to bleach a disk-shaped region of fluorescently labeled molecules in a thin sample such as a cell membrane or a lamellipodium (Fig. 26.1) (Axelrod et al., 1
