概述

concentrates 2 ml down to 15-70 µl
98% sample recovery
fast processing time - 10 to 30 minute spin times
engineered dead stop reverse spin capability provides consistent recoveries

applications

concentration of biological samples containing antigens, antibodies, enzymes, nucleic acids, or microorganisms
purification of macromolecular components found in tissue culture extracts or cell lysates
primer removal, pcr cleanup, removal of linkers or macromolecular labels from a reaction mix, and protein removal prior to hplc
desalting, buffer exchange and protein dialysis
size exclusion and protein fractionation

material supplied

the amicon ultra-2 device is supplied with two microcentrifuge tubes. during operation, one tube is used to collect filtrate; the other tube is to recover the concentrated sample.

collection tube	polypropylene
the ultrafiltration membranes in amicon ultra-2 ml devices contain trace amounts of the following:	amicon ultra 3k, 10k, 30k, 50k, 100k devices: glycerine
if these materials interfere with analysis, pre-rinse the device with buffer or milli-q water. if interference continues, rinse with 0.1 n naoh followed by a second spin of buffer or milli-q water.
