Hampton research代理 HR2-829 100% Tacsimate pH 8.0
Tacsimate pH 4, 5, 6, 7, 8, & 9
APPLICATIONS
- Crystallization grade Tacsimate for formulating screens or for optimization
FEATURES
- Sterile filtered solution
- Formulated in Type 1+ ultrapure water: 18.2 megaohm-cm resistivity at 25°C, < 5 ppb Total Organic Carbon, bacteria free (<1 Bacteria (CFU/ml)), pyrogen free (<0.03 Endotoxin (EU/ml)), RNase-free (< 0.01 ng/mL) and DNase-free (< 4 pg/µL)
DESCRIPTION
To screen pH as a crystallization variable using Tacsimate one can mix together different ratios of different pH Tacsimate solutions. Refer to the pdf “Mixing Tacsimate Stocks to Screen pH” on this page. Or, one can add a buffer to the crystallizaiton reagent containing Tacsimate. Recommended final buffer concentration in the reagent well is 0.05 to 0.1 M.
