摘要:
A penicillin of the formula: ##STR1## (i.e. 6-[D-2-(3-hydroxypyridazine-4-carbonamido)-2-(p-hydroxyphenyl)acetamido]penicillanic acid), which is valuable as an antibacterial agent, a nutritional supplement in animal feeds and a therapeutic agent in poultry and mammals including man and is especially useful in the treatment of infectious diseases caused by Gram-positive and Gram-negative bacteria.
摘要:
A human monoclonal antibody, which has prophylactic and therapeutic effect to infectious diseases caused by Pseudomonas aeruginosa of serotypes A and H classified under the Japanese Committee's Classification, and the epitope of which is located at the common structure in the O-antigen of Pseudomonas aeruginosa of serotypes A and H. A hybridoma producing said human monoclonal antibody, and processes for preparing said hybridoma and antibody are also provided.
摘要:
The objective of the present invention is to provide a gene encoding novel afadin DIL domain-binding protein (ADIP) and use of the novel ADIP protein.The present inventors successfully identified a novel afadin-binding protein (ADIP) using yeast two-hybrid screening in order to identify how the nectin and afadin system organize tight junctions and adherens junctions at the cell-cell junctions. The novel protein is useful for evaluating actin cytoskeleton-controlling agents.
