Table 2 Rates of synthesis and degradation of c-fos and c-fos-2 transcripts upon serum stimulation

From: Alternative splicing of c-fos pre-mRNA: contribution of the rates of synthesis and degradation to the copy number of each transcript isoform and detection of a truncated c-Fos immunoreactive species

  c-fos c-fos-2
NIH 3T3 cells amount (molec/pg) half-life (min) synthesis (molec/min) amount (molec/pg) half-life (min) synthesis (molec/min)
