摘要:
An object of the present invention is to provide a means for efficiently obtaining mammalian embryos having high conception rates. A first aspect of the present invention is a method for selecting a mammalian embryo prepared by in vitro culture from a fertilized egg, comprising a step of selecting an embryo using two or more of the following indicators: the time from fertilization to the completion of first cleavage; the morphology at a stage after first cleavage and before second cleavage; the morphology at a stage after third cleavage and before fourth cleavage; and the amount of oxygen consumed at the early blastocyst stage, the blastocyst stage, or the expanded blastocyst stage.

The present invention provides an electroluminescence device which can overcome a drawback that a light emitting layer deteriorates when a cathode layer is formed on the light emitting layer and has no decline in the original function; and a production method which is suitable for producing such an electroluminescence device. An electroluminescence device has a laminated structure wherein an anode layer, a light emitting layer, a charge transporting protection layer, and a cathode layer are successively formed on a substrate, in which the charge transporting protection layer comprises a transparent insulating material, or a transparent insulating material and a metal.
