WebHowever, the level of endotoxin contamination found in plasmid DNA is dependent on the purification method used . QIAGEN Plasmid Kits and 2x CsCl gradient centrifugation both yield very pure DNA with relatively low levels of endotoxoin. Silica slurry-purified DNA contains significantly higher endotoxin contamination. Web1. An isolated antibody which binds specifically to human angiopoietin-2, wherein said antibody comprises: a) a heavy chain variable domain which comprises a CDR3 region of SEQ ID NO: 1, a CDR2 region of SEQ ID NO: 2, and a CDR1 region of SEQ ID NO: 3, and b) a light chain variable domain which comprises a CDR3 region of SEQ ID NO: 4, a …
WebTraditional plasmid DNA purification methods all have some limitations[1]. Some are fast and allow isolation of nucleic acids within an hour[2], but speed usually comes at the price of reduced yield and/ or purity[3,4]. Although cesium ch loride (CsCl) plasmid purification produces high yield and purity[3,5], it requires extended periods (6 to WebPureLink™ HiPure Expi plasmid purification kits use a novel, proprietary anion-exchange resin to enable the purification of the highest levels of transfection-grade plasmid DNA. The enhanced resin combines large capacity with fast flow rate, high resolution, and efficient endotoxin removal.
