Method (primary source abstract:) "[Researchers] show by chromatin immunoprecipitation that C/EBPbeta binds the p40 promoter following lipopolysaccharide stimulation of peritoneal macrophages."
Comments "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." "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."
