How does a 280nm UV Narrow Band Pass Filter apply in life sciences?

The 280nm UV narrow bandpass filter is widely used in life sciences for various applications such as fluorescence microscopy, DNA/RNA analysis, and protein analysis.

 

In fluorescence microscopy, the filter isolates a specific excitation wavelength for fluorescence imaging of biological samples. Some fluorescent dyes and proteins have an optimal excitation wavelength of around 280nm, making this filter ideal for exciting and detecting their fluorescence.

 

In DNA/RNA analysis, the filter can be used in UV spectrophotometry to accurately measure the concentration of nucleic acids in a sample. At 280nm, nucleic acids absorb strongly and have a unique spectral signature, allowing for authentic engagement and purity measurements.

 

In protein analysis, the filter can measure the concentration of proteins in a sample based on their absorbance at 280nm. Proteins contain amino acids such as tryptophan and tyrosine, with firm absorbance peaks at 280nm. By measuring the absorbance of a sample at this wavelength, the protein concentration can be accurately determined.
