Introduction Transformation of bacteria with plasmids is not only of note for bacterial studies but also can be used for gene expression studies in mammalian cells. Most plasmids are of bacterial origin and contain both a bacterial origin of replication and an antibiotic resistance gene which can be used as a selectable marker. The process of transformation allows foreign DNA to be introduced into a cell. Genetic modifications can be made to various bacterial strains to make them more amenable to transformation. Such modifications will maintain the plasmid without rearranging the plasmid DNA. Certain treatments have been shown to increase the transformation efficiency of bacteria. These treatments make them more susceptible to either chemical or electrical based transformation, …

Epidermal Growth Factor (EGF) is a protein that stimulates cell growth and differentiation by binding to its receptor epidermal growth factor receptor (EGFR) which triggers ligand-induced dimerization which activates the intrinsic protein-tyrosine kinase activity of EGFR. This in turn initiates a signal transduction cascade that results in various biochemical changes within the cell being targeted by EGF. This ultimately leads to DNA synthesis and cell proliferation. Members of this protein family are all similar due to their shared structural and functional characteristics. Each member of the EGF family have at least one common structural motif, the EGF domain, which is characterised by six conserved cysteine residues forming three disulphide bonds. Family members include EGF, …
