We used: The Multiple by NARS.
Serum samples were processed using the Agilent Multiple Affinity Removal Column (Multiple Affinity Removal Column, 4.6 mm × 50 mm; Agilent Technologies, Palo Alto, CA), that selectively removes albumin, IgG, IgA, antitrypsin, transferrin and haptoglobin from the serum sample.
It is also cost effective when compared with methods using multiple column steps, and provides labelled targets for microarray hybridisation with an optimal coefficient of repeatability.
The limit of detection (LOD) for the method using the three columns was also approximated by multiple blank readings.
Also column names might be adapted using the "Column Rename".
This approach is helpful for reducing the total run time without sacrificing chromatographic separation, as using multiple columns reduces separation and wash times.
Other updated features include sorting using multiple columns or rows in Numbers 3.1 on OS X, the addition of new transitions and display options to Keynote, landscape viewing and editing of spreadsheets in Numbers on IOS and keyboard shortcuts object manipulation in the iWork for iCloud beta.
As this method uses multiple LC columns to reduce runtime, we evaluated column identity by investigating the ratio between target peak areas and IS area using the two columns.
There were similarities between the two forms; an example of the influence of the roll on the codex can be seen in the use of multiple columns on the pages of early codices, much like the columnar writing on the rolls.
Analysis of variance was used to compare multiple columns, and t-tests were used for two-column comparisons (the Mann–Whitney).
