Gel electrophoresis was used as the main research technique

As has been mentioned before, gel electrophoresis was used as the main research technique. Overall, it relies on the movement of ions in an electric field (Garret & Grisham, 149). The proteins were placed in a solution that contained sodium dodecyl sulfate and a dye. It should be borne in mind that sodium dodecyl sulfate performs the following functions: denaturation and separation of proteins according to their molecular weight (Scheppler et al, 163). Therefore, one can assume, that the proteins of the unknown sample if is a fake one would travel either faster or slower than those proteins of the real one. But one should take into account that the findings of this experiment will be valid under certain conditions namely that samples are not contaminated, that appropriate temperature is maintained, and that the gel contains a sufficient percentage of agarose. Thus, necessary precautions should be taken in order to meet these standards.

There are some other criteria according to which one can distinguish fish from crabmeat. Fish as a species have an increased level of antibodies or gamma globulin proteins in their bodies and this is one of the ways to detect substitution of crabmeat. (Hall, 165; Dominguez et al, 280). However, for this purpose, one should apply a set of immunological forensic techniques that are widely utilized in the field of food research. Besides, we should set stress on the idea that this is a blind experiment, which implies that the researcher is unable to predict the results of the investigation. There is a great likelihood that the unknown sample is similar to the real crabmeat and there is no reason for panic.
