What Is a Microplate Reader?
A microplate reader is a device that can simultaneously measure the absorbance of multiple samples injected into a microplate. The number of samples depends on the number of wells in the microplate, but generally dozens or more samples can be measured simultaneously, greatly improving work efficiency. They are used for research and quantification in chemistry and biology, most often for protein quantification. While they are expected to improve work efficiency, they have the disadvantage of being prone to errors due to the small amount of samples being measured.
Uses of Microplate Readers
microplate readers are used in the fields of chemistry and biology to quantify proteins and measure cell growth rates. Other applications include concentration measurement using chromogenic reaction and fluorescence polarization, which can be done safely without the use of radioactive materials. They are mainly used when handling a large number of samples at once, contributing to improved work efficiency and reduced workload for researchers. In addition, absorbance measurements often require pretreatment, and in many cases, reactions are performed in microplates.
Principle of Microplate Readers
microplate readers are capable of absorbance measurement and fluorescence measurement, each of which has different measurement principles, features, and precautions.
- Absorbance measurement
The principle of absorbance measurement, which is frequently used, is simple. The absorbance is determined by irradiating a sample in a microplate with light of an arbitrary wavelength and measuring the intensity of the light transmitted through the sample in the opposite direction. Once the absorbance is determined, the sample can be used for calibration curve and the concentration of the sample can be determined by Lambert-Baer's law. However, if the microplate is scratched or contaminated, or if air bubbles enter the sample, the correct absorbance cannot be measured and may be larger than the original value. - Fluorescence measurement
Light is irradiated onto the sample using a filter that cuts off specific wavelengths, and the light intensity in the reflected long-wavelength band is measured. This is based on the property of fluorescent materials that change to an excited state by absorbing a specific wavelength band and release energy as they return to their ground state. This energy is released as heat and light, which means that light should be detected. Since the fluorescence of the sample itself is detected, it has the feature of being able to measure with high accuracy.
