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.

  • 細胞や組織のCa2+測定など、多くのカルシウムシグナルの研究に使用されています
  • 細胞は、培養細胞を含むディッシュに溶解したインジケータを直接添加することにより、これらのカルシウムインジケータのAMエステル形態でロードできます
  • これらの細胞からの蛍光信号は、一般的に蛍光顕微鏡を使用して測定されます
  • Ca2+との結合時に、波長内のわずかなシフトで蛍光が増加します
  • さらに、これらのBAPTAベースのインジケータは、さまざまな重金属陽イオン(例:Mn 2+、Zn2+、Pb2+)をCa2+よりも大幅に高い親和性で結合します
  • 重金属選択的キレート剤を用いて、これらのイオンの存在によって引き起こされるカルシウム測定値の乱れを制御することができます
  • ラベル(Ca2+–結合型のEx/EM):X-rhod-1(580/602 nm)
  • Ca2+結合時の蛍光強度の増加:>100倍
  • バッファー中のMg2+なしのCa2+の場合のKd:約700nM

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.
Authors:Smith MC, Luker KE, Garbow JR, Prior JL, Jackson E, Piwnica-Worms D, Luker GD
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
