설명

애플리케이션

• Enzymatic/chemical analysis of dietary fiber.: Focused on the analytical techniques for analyzing dietary fibers, which could be adapted for the analysis of complex organic matrices in the presence of DMSO ( Theander et al., 1994).


• Levans: I. Fractionation, solution viscosity, and chemical analysis of levan produced by Streptococcus salivarius.: This research details the fractionation and analysis of bacterial levan, which could inform studies involving the solubilization and analysis of similar polysaccharides in DMSO ( Ehrlich et al., 1975).

주의사항

Supercools easily and remelts slowly at room temperature. Solidified product can be re-liquified by warming to room temperature without detriment to the product.
