Choosing a calcium imaging light source
Calcium imaging is a powerful technique for understanding the many biological processes controlled and mediated by Ca2+ oscillations. Ratiometric calcium imaging with dyes such as Fura-2 is a popular technique and selecting the best calcium imaging light source is crucial. Where traditional arc lamps with a monochromator were the go-to approach, LEDs have evolved significantly over the last decade. LEDs which can quickly switch between 340 nm and 380 nm now provide the ideal solution as a powerful, flexible, cost-effective and controllable calcium imaging light source.
