A lithographic printing plate precursor is disclosed including a support and a coating comprising a photopolymerisable layer including a polymerisable compound, a photoinitiator, and an infrared absorbing compound including a long chain linear or branched alkyl group.

A wavelength selective absorption filter contains a resin, a coloring agent, and a compound having at least one polar group of a carboxylic acid ester bond, a carboxylic acid amide bond, a sulfonic acid amide bond, a urethane bond, or a sulfonyl bond and a MW≤1,000 where dye includes at least one of dye A having a main absorption wavelength range at a wavelength of 390 to 440 nm and dye D having a main absorption wavelength range at a wavelength of 680 to 780 nm, a 20% value wavelength A with respect to an absorbance maximal value exhibited by a main absorption wavelength is 455 nm or less where dye A is contained, and a 20% value wavelength D with respect to the absorbance maximal value exhibited by the main absorption wavelength is 640 nm or more where dye D is contained, and a display device.

Disclosed are a leukocyte classification reagent and kit, a classification method, an erythrocyte classification reagent and kit, and an analysis method. Both the leukocyte classification reagent and the erythrocyte classification reagent comprise a fluorescent dye represented by the general formula F. The dye can stain the nucleic acids of leukocytes and erythrocytes, therefore, during blood analysis, the classification and/or counting of leukocytes in a sample can be accurately realized, and the classification and/or counting of erythrocytes in a sample can be accurately realized, in particular the identification and/or counting of RETs. In addition, the types of dyes used in blood cell analysis may also be simplified.

The total of n1 to n4 is an integer of 3 or more, and m=n1+n2+n3+n4−1 is satisfied.

At least one of R.sup.1 to R.sup.4, R.sup.13, L.sup.11 or L.sup.12 in Formula (1) and at least one of R.sup.1 to R.sup.4, R.sup.24, L.sup.11, or L.sup.12 in Formula (2) have a specific substituent.

A fluorescent dye, as well as a preparation method and uses thereof, wherein the fluorescent dye is sensitive and specific to viscosity and has low background fluorescence; it can also be used as a fluorescent activated and lighted probe used for fluorescent labeling, quantification or monitoring of protein, enzymes or nucleic acid.

This disclosure provides cyanine dye compounds having linked hydrogen bond-forming groups that can be used for detecting nucleic acids, particularly for fluorescent staining of DNA, in a biological sample. We found that the simultaneous incorporation of at least two hydrogen bond-forming groups (HBGs) into such a nucleic acid stain can provide for crosslinking interactions between the stain and the target nucleic acid, and lead to a significant increase in the detection sensitivity without substantially increasing undesirable cytotoxicity or mutagenicity properties of the dye compounds. The cyanine dye compounds can have a cyanine structure that connects two particular fused heterocycle ring systems, where at least two HBGs are connected to the core structure through linkers. Also provided are nucleic acid complexes including the cyanine dye compounds, and methods of using the compounds to detect nucleic acids in a biological sample.

An object of this invention is to provide a streptavidin mutant reduced in affinity to the naturally-occurring biotin, and to provide a modified biotin which shows a high affinity to such streptavidin mutant reduced in affinity to the naturally-occurring biotin. This invention can provide a compound composed of a dimer of modified biotin, a streptavidin mutant, and usage of them.

Provided are delocalized lipophilic cation (DLC) compounds and methods of using such compounds. Also provided are pharmaceutical compositions that include a DLC compound. Provided methods include methods of killing cells and methods of fluorescently labeling mitochondria by contacting the cells with a DLC compound of the present disclosure. Also provided are methods of imaging cell mitochondria, methods of determining whether a patient has a mitochondria related disease, and methods of treating a patient for a mitochondria related disease. Kits that include compounds of the present disclosure are also provided.
