Figure 2
Precipitant strength of the individual salts for SERCA. The individual salts were each included under many chemical conditions in the precipitant screen conducted for SERCA. Each chemical condition was rated as strong (three points), medium (two points), weak (one point) or non-precipitant (zero points) depending on what protein concentration was needed to precipitate the solution. For each salt, points awarded to the chemical conditions containing that salt were averaged and then divided by the molar concentration of the salt stock solution. This resulted in an ordering of the salts in terms of their molar precipitating strength. Sodium acetate turned out to be the strongest precipitant for SERCA, which is interesting since sodium acetate has previously been used as a crystallization agent for SERCA (Sørensen et al., 2004  ). |
