Description

NK cell immunodetection kit with good sealing performance Technical Field The utility model relates to the technical field of immunodetection, in particular to an NK cell immunodetection kit with good tightness. Background NK cell immunodetection kit is mainly used for evaluating and detecting the functional activity of Natural Killer (NK) cells, is widely applied to immunoresearch and clinical diagnosis, and has the core effects of ①, efficiently separating NK cells from peripheral blood by specific reagents (such as antibody magnetic beads) to ensure the purity of experimental samples, ②, providing cytokines (such as IL-2 and IL-15) and a culture medium to support the in vitro amplification and activity maintenance of NK cells, ③, quantitatively detecting the killing capacity of NK cells, for example, evaluating the clearance efficiency 17 of the NK cells to abnormal cells by co-culturing target cells (such as K562 tumor cell lines) and measuring LDH release or fluorescent marker signals. In addition, the kit generally comprises a calibrator and a standardized reagent to reduce experimental errors, and is suitable for tumor immunotherapy, virus infection research, immune function evaluation and the like. After the reagent bottle is opened, the staff can forget to seal immediately after operating, and the longer the inside of the reagent bottle is exposed to the outside, the more easily the reagent bottle is polluted, and then the detection result is affected.
