Cellular Use Rating
Thus compound is recommended for use in human cell lines. It may not be used in standard model organisms such as rat or mouse. However, it may be used in these model organisms in xenograft studies.
Note: The Chemical Probes Portal only endorses compounds as chemical probes for use as specific and selective modulators of the proposed target if they receive three or more (3-4) stars. Read more about our evaluation criteria
