  1. Low M values indicate high expression stability, and recalculated M values are given in brackets. The recalculated M values are given for the three most stably expressed genes according to geNorm, after elimination of the three less stable genes.
  2. Abbreviations: Dev 1 - developmental stages before activation of zygotic transcription, Dev 2 - developmental stages after hatching, A. kidney - anterior kidney, Mock - mock-injected, NNV - NNV-injected.
