Sample submission instructions
Frequently asked questions
1.  Collect tissue in 0.2 ml 8-tube strips.  Mark the tubes to make the strain and animal ID identifiable. Please do
NOT use individual 0.2 ml tubes or tear off un-used tubes even if you have fewer than 8 samples. Do NOT combine
two mouse lines in the same strip.  
2.  Immediately submerge mouse tissue in alcohol (70% - 95% EtOH).  The samples can then be stored at room
temperature indefinitely.
