StockOptions MES Buffer Kit


  • Focused, titrated buffer stocks for crystal screening, optimization, & production


  • 0.1 unit increments for fine tuning pH
  • pH 5.2 - 7.1 (20 reagents)
  • 1.0 M concentrated stocks


StockOptions Buffer kits are reagent toolboxes for the macromolecular crystal grower. Stock-Options reagent kits offer precisely formulated, high quality crystallization grade reagent stocks in convenient, cost-effective kits. The chemicals utilized in StockOptions kits are the same crystallization grade, ultra-high purity chemicals utilized in the Hampton Research kits. StockOptions reagents are carefully formulated under strict quality standards to ensure reliable performance and lot-to-lot consistency.

Preformulated stocks remove calculation, measurement, and formulation errors. No more second guessing how the reagent was formulated, what specific chemical was used, when it was made, or how to precisely reproduce that reagent when it is gone and more reagent is required for additional setups. HR2-243 contains 10 milliliters each of 20 unique MES buffer solutions titrated to the indicated pH using NaOH.
