As mentioned by others, CoCl2 helps stabilize HIF1 transcription factor. As such it only mimics HIF1 activation (as detected by gene expression profile). There are many other effect of hypoxia that are not mimiced by CoCl2 treatments.

As mentioned by other experts also, CoCl2 inhibits PHD enzymes (the oxygen sensors) through replacement of Fe with Co making these enzymes unable to mark HIF alpha for degradation. CoCl2 based/hypoxia mimetic samples are often employed in hypoxia studies as positive control for HIFs analysis.
