||(primary source abstract:) "[Researchers] adapt a novel method of fluorescent in situ hybridization to quantify the global spatio-temporal dynamics of bicoid mRNA particles."
||P.617 left column bottom paragraph: "A survey of all credible published estimates that [Biggin] could find for four well studied species suggests that most animal transcription factors are expressed at 10,000–300,000 molecules per nucleus (Table 1). These estimates are further supported by [his] own experience and that of many other biochemists who have purified additional endogenous transcription factors with similar yields to the proteins in Table 1." P.620 right column bottom paragraph: "The data in Table 1 may be biased toward easily studied proteins, so the identification of transcription factors expressed at lower levels may identify better candidates for Coselective DNA Binding-based regulation."
