Example
Poor: We performed Western blot analyses to determine the expression of MDM2. The Western blots showed that the protein was overexpressed in two of the four cell lines. We also determined whether the results of the Western blots for protein expression correlated with the mRNA expression of MDM2 using RT-PCR.
Good: We determined the expression of the MDM2 protein by Western blot analysis. We observed that the protein was overexpressed in two of the four cell lines. We then examined whether there was a correlation between the MDM2 protein expression and its mRNA level by RT-PCR.
Also be sure that you do not start every paragraph with the same word or phrase.
