A nice feature on BMG LABTECH microplate readers is Injection at the Point of Measurement. That is, as the reagent is being injected into the microplate well from the top, the specialized optics are measuring the signal from the bottom of plate at the same time. Therefore, none of the signal is lost on BMG LABTECH microplate readers. The signal can be captured as quickly as 50 measurement points a second, or once every 20 microseconds. If a microplate reader does not have Injection at the Point of Measurement, it can take several seconds after injection before the first measurement is read. If your assay is finished in seconds, these beginning measurement points will be lost. With BMG LABTECH microplate readers, this is not a concern.
Some common assays that require injection include:
- Calcium or sodium flux
- Ion voltage channels
- Dual Luciferase Assay or DLR®
- ORAC antioxidant assay
- Enzyme kinetics
- Flash luminescence or luciferase assay
