Labeled calcium indicators are molecules that exhibit an increase in fluorescence upon binding Ca2+. They have uses in many calcium signaling investigations, including measuring Ca2+ in cells and tissues that have high levels of autofluorescence and also for detecting Ca2+ release generated by photoreceptors and photoactivatable chelators. Cells may be loaded with the AM ester forms of these calcium indicators by adding the dissolved indicator directly to dishes containing cultured cells. The fluorescence signal from these cells is generally measured using fluorescence microscopy.

  • Usos en muchas investigaciones de señalización de calcio, incluida la medición de Ca2+ en células y tejidos
  • Las células se pueden cargar como éster AM de estos indicadores calcio mediante la adición del indicador disuelto directamente a las placas que contienen las células cultivadas.
  • La señal de fluorescencia de estas células se mide generalmente usando microscopía de fluorescencia
  • Presentan un aumento de la fluorescencia al unirse a Ca2+ con poco cambio en la longitud de onda
  • Además, los indicadores basados en BAPTA, como estos, se unen a varios cationes de metales pesados (por ejemplo, Mn2+, Zn2+, Pb2+) con mucha mayor afinidad que a Ca2+.
  • Las perturbaciones en las mediciones de calcio causadas por la presencia de estos iones pueden controlarse mediante quelante seleccionador de metales pesados
  • Etiqueta (Ex/Em de forma unida a Ca2+): X-rhod-1 (580/602 nm)
  • Aumento de la intensidad de fluorescencia al unirse a Ca2+: > 100 veces
  • Kd para Ca2+ en ausencia de Mg2+, en tampón: aproximadamente 700 nM

Abstract
Mitochondrial modulation of Ca2+ -induced Ca2+ -release in rat sensory neurons.
Authors:Jackson JG, Thayer SA
Journal:J Neurophysiol
PubMed ID:16760347
'Ca2+ -induced Ca2+ -release (CICR) from ryanodine-sensitive Ca2+ stores provides a mechanism to amplify and propagate a transient increase in intracellular calcium concentration ([Ca2+]i). A subset of rat dorsal root ganglion neurons in culture exhibited regenerative CICR when sensitized by caffeine. [Ca2+]i oscillated in the maintained presence of 5 mM ... More
Selective, high-resolution fluorescence imaging of mitochondrial Ca2+ concentration.

'We have developed a digital image processing technique based on highpass filtering of microfluorimetric images for selective transmission of fine image details corresponding to mitochondria. This technique enabled the detection of the mitochondrial calcium signals with high selectivity, simultaneously with the cytosolic calcium signal. The validity of this technique was ... More

'We have studied the degree to which fluorescent Ca(2+) indicator dyes, and green fluorescent protein and its variants, can be used together. We find that the most commonly used fluorescent protein, enhanced green fluorescent protein (EGFP), seriously contaminates fura 2 signals. We suggest two alternative combinations for which there is ... More
CXCR4 regulates growth of both primary and metastatic breast cancer.

Journal:Cancer Res
PubMed ID:15574767
'The chemokine receptor CXCR4 and its cognate ligand CXCL12 recently have been proposed to regulate the directional trafficking and invasion of breast cancer cells to sites of metastases. However, effects of CXCR4 on the growth of primary breast cancer tumors and established metastases and survival have not been determined. We ... More
A novel method for assessing effects of hydrostatic fluid pressure on intracellular calcium: a study with bovine articular chondrocytes.
Authors:Mizuno S
Journal:Am J Physiol Cell Physiol
PubMed ID:15643052
'Chondrocytes in articular cartilage are exposed to hydrostatic pressure and distortional stress during weight bearing and joint loading. Because these stresses occur simultaneously in articular cartilage, the mechanism of mechanosignal transduction due to hydrostatic pressure alone in chondrocytes is not clear. In this study, we attempted to characterize the change ... More
