Biomolecules form the basis of life. Biomolecular Analysis involves the characterization of polymeric biomolecules such as DNA, RNA, protein, carbohydrates and lipids as well as single biomolecules. Some of the techniques that are available include absorbance spectroscopy, fluorimetry, luminometry, gel electrophoresis, capillary electrophoresis, and analytical high performance liquid chromatography. Results generated by either 1D or 2D gel electrophoresis can be acquired and analyzed via fluorescence and phosphor storage imagers. Mass spectrometry is covered in detail in a separate section.
