Contents: 12 x 0.25 ml NoEndo Resin Vials, 12 Midi Spin Columns with Clear Spin Push Caps, 12 Centrifuge Tubes and 12 Yellow Screw Caps.
The NoEndo Mini columns incorporate a SelfSeal membrane technology which retains the NoEndo resin and sample in the batch incubation chamber. The coated membrane is specially formulated to prevent any sample from leaking into the collection tube on an orbital mixer. In a centrifuge, the membrane pores dilate and the eluate, free of endotoxin, passes into the collection tube. The contact time is maximized to ensure maximum endotoxin depletion without losses of the target protein, antibody or domain antibody. Uniquely, there is also no dilution of the sample.
