We study the entanglement detection by using mutually unbiased measurements and provide a quantum separability criterion that can be experimentally implemented for arbitrary d-dimensional bipartite systems. We show that this criterion is more effective than the criterion based on mutually unbiased base measurements. For isotropic states our criterion becomes both necessary and sufficient.
