  2. Resource Description
    "Relative Quantitation of the same protein in different samples is usually performed via spectral counting in our laboratory. This type of analysis is simple and easy to perform, as the number of times MS/MS spectra matches to a protein entry in the database has been shown to be roughly proportional to the amount of protein present. Though the analysis of this data is relatively straight forward it requires that more effort is spent on preparing the samples. Errors introduced in the sample preparation phase can result in serious problems with the analysis. Samples for this kind of analysis are usually submitted as either a liquid solution, or lyophilized powder. Single gel bands are not generally compatible with the procedure however, as the counting statistics are affected by the nature of the sample. In this case the abundance difference apparent on gel is a more useful then the spectral counting numbers."
