StockOptions Polymer is designed to help researchers improve the speed, accuracy, precision, and quality of the formulation of crystallization screen reagents and crystallization optimization reagents. Researchers can use the individual StockOptions reagents to conveniently formulate custom screen solutions or accurately reproduce standard screen solutions from Hampton Research kits such as Crystal Screen™, Crystal Screen Cryo™, Crystal Screen Lite™, Natrix™, Crystal Screen 2™, Index™, PEGRx™ 1, PEGRx™ 2 and PEG/Ion™. StockOptions Polymer reagents can also be used to create solutions for the refinement and optimization of preliminary crystallization conditions. Finally, StockOptions Polymer reagents can be used to create accurate, precise, reproducible, high quality solutions for the production of single crystals.

StockOptions Polymer contains 24 reagents in sterile, screw cap polypropylene tubes. Each tube contains 10 milliliters of reagent and is purged with argon to promote reagent stability.
