Hi, We would like to measure changes in the volume of cultured mammalian cells. The changes occur in about 10-20 seconds, and we would like to do some kinetics studies on them. So we need fairly fast sampling rate (like every second or half-second). We have a ZEISS LSM that can be used for the experiments. Any advice, including pointers to publications on the subject would be greatly appreciated. Thanks! Laszlo Menczel Biological Research Center Szeged, Hungary [log in to unmask]
