Variation of chloride readings with time.

Shown are chloride blood chemistry measures collected at week 16 by batch for those collected within 2012 for both knockout and control mice collected on the WTSI MGP Select high throughput pipeline for the core strain B6N. The dotted lines indicate the 95% percentile values. The boxplot highlighted in black shows the date on which the Expitm1a(KOMP)Wtsi female data were collected, and shows that all values collected on that date were low. Whilst these data points were low, the instruments daily QC checks were within the required boundaries.
