Sulfo DBCO-PEG3-NHS ester TEA is a click chemistry reagent containing an azide group. Sulfo DBCO-PEG3-NHS ester (TEA) is an analog of DBCO-Acid with PEG linker and a DBCO group. The DBCO group is commonly used for copper-free Click Chemistry reactions due to its strain promoted high energy. The hydrophilic PEG chain and sulfo group increase water solubility. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research use only .

Cat. No.: HY-D0924B
Synonyms: Sulfo-Cyanine5.5 tea
Cy5.5 TEA is a CY dye. CY, short for Cyanine, is a compound consisting of two nitrogen atoms connected by an odd number of methyl units. Cyanine compounds have the characteristics of long wavelength, adjustable absorption and emission, high extinction coefficient, good water solubility and relatively simple synthesis . CY dyes are of en used for the labeling of proteins, antibodies and small molecular compounds. For the labeling of protein antibodies, the combination can be completed through a simple mixing reaction. Below, we introduce the labeling method of protein antibody labeling, which has certain reference significance .

Cat. No.: HY-125678S
Jasmine lactone-d2 is deuterated labeled Jasmine lactone (HY-125678). Jasmine lactone, a volatile substance produced by plants under stress, has a strong odor and is known for its unique jasmine-like floral and fruity scent which is very popular in tea, especially in oolong and black tea. The biosynthesis mechanism of Jasmine lactone in tea is regulated by various stresses, including mechanical damage and low temperature stress. Continuous mechanical damage and low temperature and mechanical damage can enhance the accumulation of Jasmine lactone in tea .
