BD Biosciences Clontech released the BD Talon Single Step Columns last week and BD Living Colors HcRed Polyclonal Antibody this week. BD Talon purifies histidine-tagged proteins in one step, and can do so directly from bacterial culture, according to the company. A lysis buffer call xTractor lyses the cells while the BD Talon resin binds the proteins. The entire procedure takes 30 minutes, according to the com-pany. The BD Living Colors HcRed antibody detects the red fluorescent protein HcRed1.
