Ion-pair reagents (IPR) are used in reversed-phase liquid chromatography (RP-LC) and has effectively separated ionic or ionizable analytes.  Successful applications of Ion-pair Reagents Single- and double- stranded RNA / biological or synthetic (2011) [1] Stationary Phase: Non-porous polymeric columns and monolithic polymeric capillary columns Ion-Pair Reagent: Various traditional or volatile amine cation salts Detector: Fluorescent-based...

A major challenge in the development of a chromatographic method is the rational selection of experimental conditions that can provide adequate resolution in a reasonable run time. To increase the retention of ionic and polar analytes with a reversed phase column, it is important to choose an oppositely charged ion-pair...

Guide to Safely Transfer Anhydrous Reagents from a Sealed Container for Air Sensitive Reactions Many reactions in the chemistry lab are air or moisture sensitive, often causing potentially catastrophic accidents if mishandled. Common reagents such as lithium aluminum hydride, Grignard reagents, and alkali metals fall under this category. In late...

     Biological Activity For double-stranded DNA (ds-DNA) repair templates, RS-1 stimulates the binding of human HDR protein RAD51 (hRAD51) to cleavage-induced single-stranded DNA (ss-DNA) over-hangs, which enhances HDR proficiency by facilitating the formation of active presynaptic filaments and stabilizing ss-DNA-RAD51 nucleoprotein filaments, without inhibiting hRAD51 ATPase activity. [ 1 ]...

Basic Introduction of Green Chemistry Green Chemistry Green chemistry, also known as sustainable chemistry, is the design of chemical products and processes that serve to reduce or eliminate hazardous substances. With a green chemistry approach, we can better protect people and the environment by reducing and even preventing hazards and...
