CAS: 846-70-8; Naphthol Yellow S

该化合物是一种合成的黄色染料,在纺织品,食品和化妆品等各种应用中常用,其特征是亮黄色,其原因是有异声功能组(-N=N-),这种化合物具有水溶性,适合水染过程使用.酸黄1号在酸性条件下表现出良好的轻便性和稳定性,在酸性染料环境中使用是有利的.然而,它与许多异声染料一样,可能会引起对潜在毒性和环境影响的关切,特别是由于在退化时释放芳香胺的可能性.安全数据表通常建议谨慎处理它,使用适当的个人防护设备来尽量减少接触.

    权利人:KAO CORP
    摘要:The present invention is on polymers derivatized with an organic deposition-enhancing group for their enhanced deposition onto keratin fibers, especially human hair. The deposition-enhancing group is a di-hydroxyl phenolic compound with a spacer alkyl group bound to a reactive amine or carboxyl group, which reacts with one of the hydroxyl, carboxyl, primary and secondary amine groups on the polymeric backbone. The invention is on the method of synthesizing such compounds and compositions comprising the compounds.

    标题:Methods and compositions of amplifying RNA
    发明人:GINSBERG STEPHEN D; CHE SHAOLI
    权利人:BAYLOR COLLEGE MEDICINE
    摘要:The present invention pertains to a method that will increase the efficiency of second strand cDNA synthesis through a mechanism of “terminal continuationâ€? before further RNA amplification by RNA transcription using, for example, a bacteriophage promoter. In a specific embodiment, a transcription promoter is attached to the 5′ region of cDNA through the same mechanism of “terminal continuationâ€?. Genetic signals are subsequently amplified in a linear manner through RNA transcription. In specific embodiments, the orientation of the transcribed RNA is either sense or antisense, depending on the desired downstream application. In other embodiments, the present invention pertains to methods for extraction and amplification of RNA, particularly mRNA, from histologically stained tissues and cells.

    标题:Silk nanoparticle synthesis: tuning size, dispersity, and surface chemistry for drug delivery

    权利人:TUFTS COLLEGE
    摘要:Methods disclosed herein relate to generating silk nanoparticles with a low polydispersity index (PDI). Methods include adding a silk solution dropwise into a volatile solvent that is miscible with water, thereby forming a precipitate-bearing solution and applying shear forces to the precipitate-bearing solution for a length of time sufficient to achieve evaporation of at least 95% of the volatile solvent, thereby producing a population of silk fibroin nanoparticles in water having a polydispersity index (PDI) of 0.35 or less, including but not limited to, a PDI of 0.330 or less, 0.325 or less, 0.315 or less, 0.310 or less, 0.30 or less, 0.275 or less, 0.250 or less, 0.225 or less, or 0.200 or less. Parameters related to silk fibroin molecular weight, silk fibroin concentration, shear force application, and temperature may all be modified to achieve silk nanoparticles of a particular size exhibiting particular PDIs.
