Paragraph 0041; 0042; 0043; 0047, (2017/04/19)
The invention discloses a technique for preparing erythrosin B. The technique comprises the steps of 1, making fluorescein which serves as the start material react with iodate to generate erythrosine under the action of a solvent and a catalyst; 2, making the erythrosine prepared in step 1 react with alkali to generate the erythrosine B under the action of a solvent. The technique has the advantages that operation is easy, cost is low, yield is high, pollution is light, and iodine utilization rate is high. The technique is suitable for industrial production and is suitable for production of most relevant enterprises.
Assay for mycobacterium avium/intracellulare nucleic acid

, (2010/12/26)
Disclosed is a method for determining the presence of Mycobacterium avium complex nucleic acids in a biological sample. In particular, the mig gene of M. avium and the DT1 gene of M. intracellulare are detected, preferably following amplification. In addition, the method distinguishes between species of M. avium and M. intracellulare. Also described are oligonucleotides that can be used as primers to amplify target genes such as mig and DT1 genes and as probes as well as kits containing the oligonucleotides.
PROCESS FOR SYNTHESIZING HALOGENATED DERIVATIVES OF FLUORESCEIN FOR USE IN THE PRODUCTION OF NON-VOLATILE MEMORY DEVICES

Page/Page column 7, (2008/06/13)
A process performs solid phase synthesis of halogenated derivatives of fluorescein, and includes reacting fluorescein with a halide MX, wherein M is an alkali metal and X is a halogen, and Oxone? (2 KHSO5.KHSO4.K2SO4), at a temperature higher than or equal to 150° C. A structure uses a halogenated derivative of fluorescein selected from the group consisting of 2′,4′,5′-trichlorofluorescein, 2′,4′,5′,7′-tetrachlorofluorescein, 4′,5′-diiodofluorescein diacetate and 2′,4′,5′-triiodofluorescein as electro-bistable material in a non-volatile memory device.
