Publication number: 20220404380Abstract: A detection kit for detecting an immunosuppressor in whole blood by high performance liquid chromatography-tandem mass spectrometry and a detection method thereof is provided. An internal standard solution is added with an antioxidant, vitamin E, and mixed with an internal standard diluent containing zinc sulfate heptahydrate, purified water and methanol for sample pretreatment, which not only exerts the function of the internal standard, but also synchronously achieves erythrocyte treatment, protein precipitation and target substance extraction. Various embodiments enable the immunosuppressor to be more stable in a solution matrix, thus promoting the detection accuracy and sensitivity. Various embodiments adopt isotopically-labeled sirolimus as an internal standard of everolimus to substitute isotopically-labeled everolimus, thus overcoming the interference of everolimus on isotopically-labeled everolimus and satisfying the detection requirements.Type: ApplicationFiled: October 27, 2021Publication date: December 22, 2022Inventors: Shanshan Zeng, Qi Zhang, Baoyu Han, Huafen Liu

Publication number: 20220317137Abstract: The present invention describes a test kit for the detection of fat-soluble vitamins in serum using a method based on high performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS). The internal standard (IS) solution included in the kit is based on methanol, acetonitrile and isopropyl alcohol solvents. Ammonium acetate is added to the IS solution to make it more stable and last for longer storage time. The application of this kit can significantly improve the recovery and detection sensitivity of vitamins A, E, K1 and K2 in serum without additional sample enrichment, make sample preparation process simpler and more efficient, keep processed samples stable for longer time, and lower the overall cost for more accurate and repeatable test results.Type: ApplicationFiled: April 23, 2021Publication date: October 6, 2022Inventors: Shanshan Zeng, Qi Zhang, Yuan Wang, Pengyun Liu, Baoyu Han, Huafen Liu

Patent number: 10637603Abstract: In an example, a communication module includes an optical transmitter, an optical receiver, and a periodical filter. The optical transmitter is configured to emit an outbound optical signal. The optical receiver is configured to receive an inbound optical signal. A first frequency of the outbound optical signal is offset from a second frequency of the inbound optical signal by an amount less than a channel spacing of a multiplexer/demultiplexer implemented in an optical communication system that includes the communication module. The periodical filter is positioned in optical paths of both the outbound optical signal and the inbound optical signal and has a transmission spectrum with periodic transmission peaks and troughs. The first frequency of the outbound optical signal may be aligned to one of the transmission peaks and the second frequency of the inbound optical signal may be aligned to one of the transmission troughs, or vice versa.Type: GrantFiled: May 14, 2019Date of Patent: April 28, 2020Assignee: Finisar CorporationInventors: Leo Yu-Yu Lin, Huade Shu, Huiping Li, Li Zhang, Shanshan Zeng, Guangsheng Li
