The PGA Eco Screen™ MD1-50-ECO
A version of the PGA Screen of 96 premixed conditions at 10 mL, where cacodylate has been replaced by MES.
This kit is based on the poly-γ-glutamic acid polymer, PGA and is the first of a new breed of chemical polymers that exploit poly-amino acids to unlock new areas of crystallization space.
The high nucleation-precipitation potential of PGAs enables their use at very low concentrations and in combination with classical precipitants, thus scaling down the amount of precipitant necessary for crystal appearance and growth. This feature of PGAs makes them especially useful in applications for labile, easily precipitating proteins.
All our Eco Screens are free from nasties such as cacodylate, azides and dioxane.
