| description | 2D electrophoresis (2-DE) is a proteomic tool that has been widely used as this
technique is capable of resolving and separating thousands of proteins in a single gel for
parallel analysis. 2-DE allows the identification of individual protein and understanding
of the host-pathogen interaction during their molecular crosstalks. In addition, this
modification technique also allows the study of protein profiling of solid biological
samples. However, the analytical conditions need to be optimized to achieve optimal parameters and
procedures for 2-D gel images. In the present study, optimization was carried out which aimed to
improve image quality, reproducibility and sensitivity of 2-D gel. Generally, focusing time
and voltage of Isoelectric focusing (IEF) affect the reproducibility of 2-D gel images
for protein analysis. It was found that increasing voltage and time for IEF running were optimal
for 2-DE. Reducing development time, enhancing the washing step, prolong fixation to
overnight and the use of freshly prepared reagents of silver staining produced better
image resolution and enhanced sensitivity. |
