Comments Value from reference, range from primary source abstract: "The specific activity of recA protein is maintained at a relatively constant "basal' level (800 to 1,200 molecules per cell for wild-type E. coli in L-broth, salt-depleted broth and minimal media) during early-log and mid-log phase growth, but it increases by two- to ten-fold as the culture approaches saturation density."
