  • Patent number: 11987850
    Abstract: The present application relates to a field of a biological detection technology, in particular, relates to a universal probe, a primer-probe set and a kit. The present application provides a universal probe, in which, from 5? end to 3? end, the universal probe sequentially comprises: quenching group-fragment A -fluorophore-fragment B-C3; the fragment A has a nucleotide sequence selected from a group consisting of SEQ ID NO:1-7; and the fragment B has a nucleotide sequence selected from a group consisting of SEQ ID NO:8-14. The present application further provide a primer-probe set, an application and the kit.

  • Patent number: 11964271
    Abstract: The present application discloses drop preparation device and drop preparation method and relates to the technical field of biochip. In the drop preparation device, the chip, the temperature control module and the pressure detection unit are provided in the cavity, the temperature control module is configured for adjusting a temperature value in the chip, and the pressure detection unit is configured for detecting a pressure data in the cavity; two chip ports, that is, a sample inlet and an oil inlet are provided at the top of the chip; the perforated cap has a vent hole and is elastically deformed to change a volume of the vent hole. When the perforated cap is directly connected to the oil inlet, the pressing assembly is lifted or lowered to open or cover the vent hole. When the pressing assembly covers the oil inlet, a pressure difference is formed in the chip.

  • Publication number: 20240024504
    Abstract: The subject invention pertains to methods of acetylation of the Fc region of immunoglobulins, particularly Lys248 of the heavy chain of human Immunoglobulin G (IgG) using a novel Fc-III derived peptide. The acetylation reaction with the phenolic ester with an azide or alkyne enables site-selective functionalization of Lys248 with a bioorthogonal reactive group for further derivatization. Further methods are provided to synthesize an antibody-lipid conjugate that allows for the construction of an immunoliposome that can target cells expressing oncogenes, including HER2+ cells, and a bispecific antibody complex (bsAbC) linking two distinct antibodies. The bsAbC can induce an effector-cell mediated cytotoxicity at nanomolar concentrations.
