+<p>BXD strains:</p>

+<ul>
+ <li>The first 32 of these strains are from the Taylor series of BXD strains generated at the Jackson Laboratory by Benjamin A. Taylor. BXD1 through BXD32 were started in the late 1970s, whereas BXD33 through 42 were started in the 1990s.</li>
+ <li>In 2004, BXD24/TyJ developed a spontaneous mutation, rd16 which resulted in retinal degeneration and was renamed BXD24b/TyJ (BXD24 in this database). The strain, BXD24a, was cryo-recovered in 2004 from 1988 embryo stocks (F80) and does not exhibit retinal degeneration. In 2009, BXD24b was renamed BXD24/TyJ-Cep290rd16/J by JAX Labs to reflect the discovery of the genetic basis of the mutation. At the same time BXD24a was then referred to just as BXD24/TyJ by Jax Labs, but still called BXD24a in this dataset.</li>
+ <li>The other 36 BXD strains (BXD43 and higher) were bred by Lu Lu, Jeremy Peirce, Lee M. Silver, and Robert W. Williams starting in 1997 using B6D2 generation 10 advanced intercross progeny. This modified breeding protocol doubles the number of recombinations per BXD strain and improves mapping resolution (Peirce et al. 2004). All of the Taylor series of BXD strains and many of the new BXD strains are available from the Jackson Laboratory. All of the new BXD strains (BXD43 and higher) are also available directly from Lu Lu and colleagues at the University of Tennessee Health Science Center in Memphis, TN, USA. BXD24/TyJ is now known as BXD24b/TyJ and has nearly complete retinal degeneration. BXD24a/TyJ, a 1988 F80 inbred stock that has been rederived from cryogenic storage, does not have retinal degeneration (stock number 005243) and is an ideal coisogenic control, but is not included in the HEI data set.</li>

This data set consists of 75 BXD strains, C57BL/6J, DBA/2J, both reciprocal F1s, and BALB/cByJ. A total of 80 strains were quantified. The data are now open and available for analysis.</p>
+
+<p>This is RMA expression data that has been normalized using what we call a 2z+8 scale, but without special correction for batch effects. The data for each strain was computed as the mean of four samples per strain. Expression values on a log2 scale range from 6.25 to 18.08 (11.83 units), a nominal range of approximately 3600-fold. After taking the log2 of the original non-logged expression estimates, we convert data within an array to a z score. We then multiply the z score by 2. Finally, we add 8 units to ensure that no values are negative. The result is a scale with a mean expression of the probes on the array of 8 units and a standard deviation of 2 units. A two-fold difference in expression is equivalent roughly to 1 unit on this scale.</p>
