BioNumbers is in its infancy and there are notable gaps in the available data. Search results often contain false positives.
Please suggest missing data and references to help remedy these shortcomings (feedback box on the left).
Caution: reported numbers depend upon experimental conditions which are provided as part of the BioNumbers entry.
Search tips: Try not limiting organism. Try abbreviations, full names etc., e.g. 'Oxygen' or 'O2'.
