摘要:
According to the present invention, 22,23-dihydroavermectin B1a, which is useful as a medicine, a veterinary drug, and a pesticide, can be directly fermented and produced. This can obviate the need for the complicated and difficult conventional processes for purifying avermectin B1a at an industrial level and for chemically modifying avermectin B1a and can significantly decrease cost and time required in the industrial production of 22,34-dihydroavermectin B1a. The production of the formulation containing only 22,23-dihydroavermectin B1a, which is highly effective as a medicine, is also realized.

摘要:
The present invention provides a technology for creating functional inner ear stria vascularis marginal cells that are potentially applicable for screening of agents and pathological analysis of hearing impairment. A method for producing inner ear stria vascularis marginal cells includes a step of culturing a cell population including inner ear progenitor cells in an insulin-free culture medium that does not contain insulin or contains insulin only in a trace amount.
摘要:
It is an object of the present invention to provide a transmission-blocking vaccine using an immunogenic protein which is specifically expressed in the oocyst stage of malaria parasites or a peptide fragment thereof, and an oral transmission-blocking vaccine capable of immunizing various animals involved in the malaria infectious cycle with such a vaccine. The present invention relates to a malaria transmission-blocking vaccine for oral administration containing an immunogenic protein derived from malaria parasite which is specifically expressed in the oocyst stage of malaria parasites or a peptide fragment thereof, and a method of blocking the transmission of malaria using the same.
