The role of electrostatic interactions in the viral capsid assembly process was studied by comparing the assembly process of a truncated hepatitis B virus capsid protein Cp149 with its mutant protein D2N/D4N, which has the same conformational structure but four fewer charges per dimer. The capsid protein self-assembly was investigated under a wide range of protein surface charge densities by changing the protein concentration, buffer pH, and solution ionic strength. Lowering the protein charge density favored the capsid formation. However, lowering charge beyond a certain point resulted in capsid aggregation and precipitation. Interestingly, both the wild-type and D2N/D4N mutant displayed …

This paper describes a series of experiments involving handling and manipulating the DNA coding for Green Fluorescent Protein (GFP) including the subcloning of this gene, and mutating the DNA so that Cyan Fluorescent Protein (CFP) or Blue Fluorescent protein (BFP) are expressed. The primers needed for the PCR based subcloning of GFP are presented, as are those needed to mutate the GFP to either CFP or BFP.
