Redi-Dri™ – The World of Free-flowing Hygroscopic Products

Redi-Dri™ prevents hygroscopic powders, such as inorganic salts, from absorbing moisture and forming clumps, leaving the salts free-flowing every time.

Molecular systems biology, 10, 754-754 (2014-10-19)
Most complex disease-associated genetic variants are located in non-coding regions and are therefore thought to be regulatory in nature. Association mapping of differential allelic expression (AE) is a powerful method to identify SNPs with direct cis-regulatory impact (cis-rSNPs). We used

Sulfhydryl-containing compounds, including thiols and hydrogen sulfide (H2S), play important but differential roles in biological structure and function. One major challenge in separating the biological roles of thiols and H2S is developing tools to effectively separate the reactivity of these

Epigenetics, 9(9), 1238-1251 (2014-07-24)
Allele-specific (AS) assessment of chromatin has the potential to elucidate specific cis-regulatory mechanisms, which are predicted to underlie the majority of the known genetic associations to complex disease. However, development of chromatin landscapes at allelic resolution has been challenging since
