n-Butanol is useful for the removal of ethidium bromide from DNA purified by CsCl gradient ultracentrifugation. It is also suitable for use in the concentration of dilute nucleic acid solutions by repeated extractions. Increased nucleic acid concentration improves recovery by ethanol precipitation.

beta Glucuronidase is extracted from red abalone ( Haliotis Rufescens ). This is the most widely utilized and stable reagent for cleaving the glucuronide from drug metabolites. The amber solution prepared can be stored at 2-8°C and has a shelf life of one year. This amber solution is…

N,N,N',N'-Tetramethylethylenediamin is a tertiary amine base. N,N,N',N'-Tetramethylethylenediamine is used to catalyze the formation of free radicals from ammonium persulfate or riboflavin. The free radicals will cause acrylamide and bis-acrylamide to polymerize to form a gel…
