Calcium is used by most cells to convert external signals into biochemical events within the cytosol. To detect the effects of cold stress, a gene encoding apoaequorin has been introduced into various cell types that, in the presence of coelenterazine, allows calcium levels to be monitored by the emission of blue light. All cell types respond to the cold by elevating calcium. This event is rapid after cold stress but then shows a slower kinetic response. The magnitude is dependent on both the… CONTINUE READING
