| Hybridization protocol |
Arrays were blocked with BSA overnight, and serum samples (diluted 1:50) was incubated on the array for 4 hours at 37 C and gentle agitation (100 RPM). Slides were then washed with PBS contain 0.05% Tween (PBST). After washing, bound antibodies were detected with fluorescently labeled secondary antibodies. Slides were then washed with PBST, spun dry in a centrifuge, and scanned.
|
| Scan protocol |
Slides were scanned with a Genepix 4000A fluorescence scanner at two gain settings (typically 430 and 520) in order to increase dynamic range. Signal from ch1 (532 nm) was analyzed to determine the level of bound DyLight 549 conjugated secondary antibody specific for human IgG. Signal from ch2 (635nm) was analyzed to determine the level of bound DyLight 649 secondary antibody specific for human IgM. Scanned images were analyzed with Genepix Pro (v6.0) to determine the fluorescence and background signal for each array component.

| Description |
Test Set - Subject #63
|
| Data processing |
First, median pixel intensity of each feature was background subtracted. Second, signals for features that were saturated at the high photomultipler tube (PMT) setting were calculated by proportionally scaling the value from the low PMT setting according to a correction factor, which was calculated based on mid-intensity signals measured at the high and low PMT settings. To account for slide-to-slide variations in array processing, microarray data were normalized by median centering based on a reference serum sample analyzed on each slide. Additionally, a minimum signal of 150 was set as the floor. Since array features were printed in duplicate and all samples were analyzed on two slides, pre-processing averaged normalized data from 4 technical replicates. Final data are reported on a log 2 scale.
Signals for IgG and IgM were analyzed independently and are available as supplementary data linked to GSE68403. Raw (.gpr) files are also available as supplementary data linked to GSE68403. See README file for details.
