LDS-751
Lds-751 is a nucleic acid stain that mainly detects DNA. Lds-751 is a nucleic acid stain that mainly detects DNA. Lds-751 has a high affinity for DNA and fluorescence is enhanced after binding, but the maximum emission wavelength is 670nm. Lds-751 and Thiazole orange can be used for the differentiation of red blood cells, platelets, reticulocytes, and nucleated cells and can be stimulated at 488nm. Studies have shown that LDS-751 binds almost exclusively to mitochondria when incubated with nucleated living cells. After nucleated Acridine Orange (HY-101879) staining and LDS-751 treatment of cells, confocal microscopy revealed almost no co-location of the cells. Staining with Rhodamine 123 (HY-D0816), a dye known to bind polarized mitochondria, was almost identical to the pattern observed with LDS-751[1][2][3]. Uses: Scientific research.

leachianone-G 2''-dimethylallyltransferase
This membrane-bound enzyme is located in the plastids and requires Mg2+ for activity. The reaction forms the lavandulyl sidechain of sophoraflavanone G by transferring a dimethylallyl group to the 2'' position of another dimethylallyl group attached at postiion 8 of leachianone G. The enzyme is specific for dimethylallyl diphosphate as the prenyl donor, as it cannot be replaced by isopentenyl diphosphate or geranyl diphosphate. Euchrenone a7 (a 5-deoxy derivative of leachianone G) and kenusanone I (a 7-methoxy derivative of leachianone G) can also act as substrates, but more slowly. Along with EC 1.14.13.103 (8-dimethylallylnaringenin 2'-hydroxylase) and EC 2.5.1.70 (naringenin 8-dimethylallyltransferase), this enzyme forms part of the sophoraflavanone-G-biosynthesis pathway. Group: Enzymes. Synonyms: LG 2''-dimethylallyltransferase; leachianone G 2''-dimethylallyltransferase; LGDT. Enzyme Commission Number: EC 2.5.1.71. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder.
