In wet areas around the sink, and especially its drain, Enriquez's group has measured up to 10,000 colony-forming units per milliliter of moisture sampled. Sponges and sinks and rags, oh my! Where microbes lurk and how to rout them The four contaminated platelet pools, each derived from ...

The goal of this study was to investigate the clinical significance of enterococci growing in numbers lower than 100,000 colony-forming units per milliliter (cfu/ml) in urine samples. Clinical parameters were collected from patients whose midstream clean-catch urine samples grew Enterococcus spp. ...
Murine bioassay activities were normalized and converted to units per milliliter by dividing by the number of colonies per unit determined from an L-cell CSF-1 standard calibrated against a stable human urinary CSF-1 preparation31 and included in each bioassay (1 unit is approximately 0.22 femto...
The standard assays were performed using between 30,000 and 50,000 bone marrow cells per milliliter. Eight separate bone marrows stimulated by the purified bacterially synthesized hGM-CSF yielded an average spe cific activity of 2.9 ± 1.9 × 107 U/mg of protein after seven days in culture....
The Mars Radiation Environment Experiment discovered that the pathetic Martian atmosphere would let through enough radiation to expose the colonists to 73 milliGrays per year (mGy/a, where "a" {per annum} = 8760 hours = 365 days). On Terra people suffer about 0.4 mGy/a from GCR, and ...
Despite the in vivo response of the white-cells, the concentration of colony-forming cells remained the same. Measurable concentrations of interleukin-2 (2 to 15 units per milliliter) were found in the serum of 8 patients, and high levels of erythropoietin (81 to 1200 IU per liter) were ...
Using an immunoassay, the estimated amounts of were less than or equal to 40 pg per flask in adherent layers, while remaining undetectable in supernatants. The addition of 10 ng or purified recombinant per milliliter of culture medium increased slightly the CFU-GM output over a 5-week culture...
Twenty-five to fifty units of r-IL 2 per milliliter of culture medium provided optimal stimulation. Under these conditions, a linear relationship was observed between plated cell numbers and colony numbers formed. Morphological and immunologic analysis of colony cells indicated that these were ...
