This guide applies to many, but not all antibodies.  Always consult the product insert of the antibody for storage and handling instructions.

Spectrophotometric analysis, also called spectral scanning, of biomolecules serves two main purposes – the quantitation of nucleic acids (DNA and RNA) and purity assessment. Since the amount or concentration and purity of the DNA or RNA in a solution significantly affect the results of subsequent downstream applications, establishing these values early on can reduce, if not totally eliminate, the risk of committing errors and guarantee optimum results.
