The INIA M430 brain Database (April05) consists of 105 Affymetrix 430A and 430B microarray pairs. Each pair was hybridized in sequence (A array first, B array second) with a pool of brain tissue (forebrain minus olfactory bulb, plus the entire midbrain) taken from three adult animals of closely matched age and the same sex. RNA was extracted at UTHSC by Lu Lu, Zhiping Jia, and Hongtao Zhai. All samples were subsequently processed in the INIA Bioanalytical Core at the W. Harry Feinstone Center of Excellence by Thomas R. Sutter, Shirlean Goodwin, and colleagues at the University of Memphis.

Replication and Sample Balance: Our goal is to obtain data for independent biological sample pools from at least one of sample from each sex for all BXD strains. We have not yet achieved this goal. Ten of 45 strains are still represented by single sex samples: BXD2 (F), BXD8 (F), BXD15 (F), BXD18 (F), BXD25 (F), BXD29 (F), BXD33 (M), BXD45 (F), BXD77 (M), and BXD90 (M). Eleven strains are represented by three independent samples with the following breakdown by sex: C57BL/6J (1F 2M), DBA/2J (2F 2M), B6D2F1 (2F 2M) + D2B6F1 (1F 1M), BXD6 (2F 1M), BXD13 (2F 1M), BXD14 (1F 2M), BXD28 (2F 1M), BXD34 (1F 2M), BXD36 (1F 2M), BXD38 (1F 2M), BXD42 (1F 2M).

Batch Structure: Before running the first batch of 30 pairs of array (dated Jan04), we ran four test samples (Nov03). The main batch of 30 includes the four test samples (four technical replicates). The Nov03 data was combined with the Jan04 data and was treated as a single batch that consists of one male and one female pool from C57BL/6J, DBA/2J, the B6D2F1 hybrid, 11 female BXD samples, and 11 male BXD samples. The second large batch was run February 2005 (Feb05) and consists of 71 pairs of arrays. Batch effects were corrected at the individual probe level as described below.

The table below summarizes information on strain, sex, age, sample name, batch result date, and source of mice.
