R-M-5415 ROX NHS ester, 5 and 6 isomers ROX NHS ester, 5 and 6 isomers,Rhodamine X NHS ester , 5 and 6 isomers from ruixi.Rox, also known as rhodamine 101, is the abbreviation of rhodamine x (or x-rhodamine). X in the name indicates that rhodamine amino group is replaced by cyclization. In the field of fluorescent dyes, Rox often refers to Rox derivatives with 5 / 6 carboxylic acid structure, which can be used for the activation and labeling of fluorescent dyes. Rox is a fluorescent dye commonly used in the laboratory. It has good fat solubility and poor water solubility. It is often used as a fluorescent reporter of biological probes that need membrane penetration NHS activated ester (N-hydroxysuccinimide ester, successful ester, Se) is the most commonly used activated group in biomarker reaction. NHS activates the carboxyl group in the dye molecule, so that it can react with the amine group (main primary amine) on the target biological molecule to form a stable amide bond, so as to label the dye molecule on the biological macromolecule. price>
R-M-5416 Rhodamine X carboxylic acid  Rox, also known as rhodamine 101, is the abbreviation of rhodamine x (or x-rhodamine). X in the name indicates that rhodamine amino group is replaced by cyclization. In the field of fluorescent dyes, Rox often refers to Rox derivatives with 5 / 6 carboxylic acid structure, which can be used for the activation and labeling of fluorescent dyes. Rox is a fluorescent dye commonly used in the laboratory. It has good fat solubility and poor water solubility. It is often used as a fluorescent reporter of biological probes that need to penetrate the membrane. The product is Rox carboxylic acid, and the functional groups are not activated. Therefore, the labeled dye will not react with any functional groups and is very stable in organic solvents or aqueous solvents. price>
R-M-5417 ROX amine Rox, also known as rhodamine 101, is the abbreviation of rhodamine x (or x-rhodamine). X in the name indicates that rhodamine amino group is replaced by cyclization. Rox is a fluorescent dye commonly used in the laboratory. It has good fat solubility and poor water solubility. It is often used as a fluorescent reporter of biological probes that need membrane penetration (Rox amine) the product contains amino functional groups and can react with functional groups such as carboxylic acid. 6 carbon short chain helps to separate dye molecules from labeled objects, improve labeling efficiency and reduce the impact of labeled objects on dye molecules. price>
R-M-5418 X-Rhodamine maleimide Rox, also known as rhodamine 101, is the abbreviation of rhodamine x (or x-rhodamine). X in the name indicates that rhodamine amino group is replaced by cyclization. Rox is a fluorescent dye commonly used in the laboratory. It has good fat solubility and poor water solubility. It is often used as a fluorescent reporter of biological probes that need membrane penetration (x-rhodamine maleimide) the active group of the product is maleimide. Maleimide is a group commonly used in biomarker reaction. It can generate stable thioether structure through affinity addition reaction with sulfhydryl (- SH), so as to realize labeling. price>
R-M-5419 Rhodamine Red-maleimide Rhodamine red, also known as sulfonated rhodamine B, and lissamine rhodamine B (LRB), is a sulfonated substituted rhodamine B. Its excitation and emission peaks are 570 nm and 590 nm, respectively. The emission spectrum is between tetramethylrhodamine and Texas Red. It is a common fluorescent dye. Similar to Dezhou red, rhodamine red has its own sulfonate ion, which has good water solubility and is conducive to biomarker Maleimide is a group commonly used in biomarker reaction. It can generate stable thioether structure through affinity addition reaction with sulfhydryl (- SH), so as to realize labeling. Although amino groups (such as lysine arginine side chain) also have affinity, maleimide selectively labels sulfhydryl groups in neutral or slightly acidic buffer (reaction speed > 1000 times faster than amino groups). The labeling reaction has the advantages of rapid reaction, high selectivity and good yield. In addition, sulfhydryl is a functional group widely existing in biomolecules, such as serine and disulfide bond in proteins. Therefore, maleimide / thiol labeling has become the most commonly used biological ligation reaction second only to NHS / amino labeling. price>
R-M-5420 Rhodamine Red-amine Rhodamine red, also known as sulfonated rhodamine B, and lissamine rhodamine B (LRB), is a sulfonated substituted rhodamine B. Its excitation and emission peaks are 570 nm and 590 nm, respectively. The emission spectrum is between tetramethylrhodamine and Texas Red. It is a common fluorescent dye. Similar to Dezhou red, rhodamine red has its own sulfonate ion, which has good water solubility and is conducive to biomarker (rhodamine red amine) the product contains amino functional groups and can react with functional groups such as carboxylic acid. 6 carbon short chain helps to separate dye molecules from labeled objects, improve labeling efficiency and reduce the impact of labeled objects on dye molecules. price>
R-M-5421 Texas Red NHS ester Texas Red NHS ester,Sulforhodamine 101, nhs from ruixi.Texas Red, also known as sulfonated rhodamine 101, is a traditional but still commonly used red fluorescent dye. The main excitation peak of Texas Red dye is 589 nm, and it can also be excited by krypton laser at about 567 nm. The excitation efficiency is slightly lower. The fluorescence emission peak of Dezhou red is about 615 nm, which belongs to the visible area of human flesh eye and is more sensitive. Dezhou red molecule has sulfonate ion, good water solubility and bright fluorescence. It can be used to develop antigens with very low expression NHS activated ester (N-hydroxysuccinimide ester, successful ester, Se) is the most commonly used activated group in biomarker reaction. NHS activates the carboxyl group in the dye molecule, so that it can react with the amine group (main primary amine) on the target biological molecule to form a stable amide bond, so as to label the dye molecule on the biological macromolecule. price>
