Abstract: According to one embodiment, a substance delivery carrier and a composition are used for delivering an intended substance to a myeloid tumor cell. The substance delivery carrier has a lipid particle, and an intended substance encapsulated in the lipid particle. The lipid particle contains, as a constituent thereof, at least a first lipid represented by formula (I).

Abstract: According to one embodiment, a set of nucleic acid constructs which detects a DNA homologous recombination deficiency includes a first nucleic acid construct and a second nucleic acid construct. The first nucleic acid construct includes a first promoter sequence and a cleaved Cre gene ligated to downstream of the first promoter sequence. The second nucleic acid construct includes a second promoter sequence, a first loxP sequence ligated to downstream of the second promoter sequence, a reporter gene ligated to downstream of the first loxP sequence, and a second loxP sequence ligated to downstream of the reporter gene.

Abstract: According to one embodiment, a nucleic acid construct is used for detecting an estrogen-sensitive cell. The nucleic acid construct includes an enhancer sequence, a promoter sequence and a reporter gene. The enhancer sequence includes at least an ERE sequence and at least a XRE sequence. The promoter sequence is ligated to downstream of the enhancer sequence. The reporter gene is ligated to downstream of the promoter sequence.

Abstract: According to one embodiment, a method for determining a characteristic of a tumor cell group, the method includes bringing a lipid particle including a lipid membrane and a first nucleic acid included in the lipid membrane into contact with the tumor cell group (the first nucleic acid including a promoter sequence of a marker gene for determining the characteristic and a reporter gene linked to a downstream of the promoter sequence to be functionable), culturing the tumor cell group, detecting the presence or absence or an amount of a signal from a reporter protein that is expressed from the reporter gene, in each tumor cell included in the tumor cell group, and counting the number of tumor cells having the characteristic that is measured from a result of the detecting.

Abstract: A chicken B cell that expresses a variety of human antibodies.

Abstract: According to one embodiment, an examination device includes a reagent, a sheet and a detection unit. The reagent reacts with a measurement target and thereby causes light emission. The sheet is capable of adsorbing the reagent and gradually releasing the adsorbed reagent. The detection unit detects optical characteristics of the light emission caused by the reaction between the measurement target and the reagent.

Abstract: A genetically modified animal that includes an introduced DNA including a functionally linked aryl hydrocarbon receptor-binding enhancer located 5?-upstream of a tyrosine hydroxylase gene, promoter of any type, reporter gene, and poly(A) addition signal.
