| Source name |
MGUS_CD138+ selected cells
|
| Organism |
Homo sapiens |
| Characteristics |
subject condition: monoclonal gammopathy of uncertain significance
cell type: CD138+ selected cells from bone marrow aspirates
restriction enzyme used: MspI
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Following Ficoll-Hypaque gradient centrifugation, plasma cells obtained from the bone marrow were isolated from the mononuclear cell fraction by immunomagnetic bead selection using a monoclonal mouse anti-human CD138 antibody (Miltenyi-Biotec, Auburn, CA). Total More than 90 percent of the cells used for gene expression profiling were plasma cells, as shown by two-color flow cytometry using CD138+/CD45- and CD38+/CD45- markers.Genomic DNA was isolated using Puregene Cell and Tissue Kit according to the manufacturer instructions (Qiagene). Representation of the genome generated by digestion with either MspI or HpaII and amplification by ligation-mediated PCR according to the HELP protocol Khulan B et al.

| Description |
LMM06024B
Methylation data from HELP assay
|
| Data processing |
Signal intensities at each HpaII amplifiable fragment were calculated as a robust (25% trimmed) mean of their component probe-level signal intensities. Any fragments found within the level of background MspI signal intensity, measured as 2.5 mean-absolute-differences (MAD) above the median of random probe signals, were categorized as “failed.” These “failed” loci therefore represent the population of fragments that did not amplify by PCR, whatever the biological (e.g. genomic deletions and other sequence errors) or experimental cause. On the other hand, “Methylated” loci were so designated when the level of HpaII signal intensity was similarly indistinguishable from background.PCR-amplifying fragments (those not flagged as either “methylated” or “failed”) were normalized using an intra-array quantile approach wherein HpaII/MspI ratios are aligned across density-dependent sliding windows of fragment size-sorted data (described in detail in Thompson et al, Bioinformatics 2008;24:1161-1167.)
