Cell preparation Adherent cells: Discard the cell culture medium, digest with trypsin, prepare a single cell suspension, centrifuge at 1000 rpm for 5 minutes, and discard the supernatant. The pellet was resuspended with 1 ml of pre-cooled PBS. Centrifuge again at 1000 rpm for 5 minutes and discard the supernatant. Suspended cells: The cell suspension was collected, centrifuged at 1000 rpm for 5 minutes, and the supernatant was discarded. The pellet was resuspended with 1 ml of pre-cooled PBS. Centrifuge again at 1000 rpm for 5 minutes and discard the supernatant. Histiocytes: After cutting the tissue pieces into the smallest possible pieces with scissors, digested with 0.25% trypsin for 0.5-1 hour. Filtering through a 200-400 mesh screen to obtain a single cell suspension. Centrifuge at 1000 rpm for 5 minutes, discard the supernatant, and resuspend the pellet with 1 ml of pre-cooled PBS. Centrifuge again at 1000 rpm for 5 minutes and discard the supernatant. Note that for the last centrifugation, discard the supernatant and leave 50 μl of the supernatant, vortex and mix well.\u003cbr\u003e2. Cell fixation The cell pellet is gently mixed with 1 ml-20 °C pre-cooled 75% ethanol, and fixed at 4 °C for more than 2 hours or overnight. Then, centrifuge at 1000 rpm for 5 minutes, gently discard the supernatant, resuspend the pellet with 1 ml of pre-cooled PBS, centrifuge at 1000 rpm for 5 minutes, discard the supernatant.\u003cbr\u003e3. Staining PI staining working solution configuration: Add 25μl PI staining solution (solution A) and 10μl RNase A (solution B) to 0.5 ml staining buffer solution (solution C), mix well and set aside. Add 0.5 ml of the prepared PI staining working solution to each cell sample, and gently mix and resuspend the cells. Incubate at 37 ℃ for 30 minutes in the dark from light, and detect directly by flow cytometry (it is preferable to complete within 5 hours). The excitation wavelength was 488 nm and red fluorescence was detected. Note: Not more than 1 × 10 cells per test\u003csup\u003e6\u003c\/sup\u003eOne.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBeilstein\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSynonym\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCell cycle and apoptosis detection kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDescription\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003eThis product is based on Propidium iodide (PI) staining method to analyze cell cycle and apoptosis. Propidium iodide is a double-stranded DNA dye. Its intercalation in double-stranded DNA can produce fluorescence. The intensity of fluorescence is directly proportional to the amount of double-stranded DNA.\u003cbr\u003eIn the normal cell cycle, there is one set of chromosomes in G0 and G1 phases, two sets of chromosomes in G2 and M phases cells, and the S phase is in between. After PI staining, the fluorescence intensity of cells in different cell cycles is different. Assuming that the fluorescence intensity of cells in G0 and G1 phases is 1, then the fluorescence intensity of cells in G2 and M phases is 2, and the cells in S phase are between 1 and 2.\u003cbr\u003eDuring apoptosis, due to nucleus shrinkage and DNA fragmentation, DNA fragments will be lost from the perforated cell membrane during staining. When detected by flow cytometry, the fluorescence intensity is less than 1, that is, Sub-G1 peak or apoptotic cell peak.\u003cbr\u003eApoptosis can also be detected by observing changes in cell light scattering by flow cytometry. In the early stage of apoptosis, chromatin shrinks, cell density increases, and forward angle light dispersion decreases significantly. In the later stage of apoptosis, cells produce apoptotic bodies, and both forward angular light scattering and lateral angular light scattering are significantly reduced.\u003cbr\u003e\u003cbr\u003eProduct Components:\u003c\/p\u003e\n\u003ctable style=\"border-collapse: collapse; width: 47.6576%;\" border=\"1\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 10.7955%; text-align: center;\"\u003eserial number\u003c\/td\u003e\n\u003ctd style=\"width: 19.0183%; text-align: center;\"\u003eName\u003c\/td\u003e\n\u003ctd style=\"width: 11.0599%; text-align: center;\"\u003e50T\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 10.7955%; text-align: center;\"\u003eA\u003c\/td\u003e\n\u003ctd style=\"width: 19.0183%; text-align: center;\"\u003ePropidium Iodide (20 ×)\u003c\/td\u003e\n\u003ctd style=\"width: 11.0599%; text-align: center;\"\u003e1.25 ml\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 10.7955%; text-align: center;\"\u003eB\u003c\/td\u003e\n\u003ctd style=\"width: 19.0183%; text-align: center;\"\u003eRNase A (50 ×)\u003c\/td\u003e\n\u003ctd style=\"width: 11.0599%; text-align: center;\"\u003e500 μl\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 10.7955%; text-align: center;\"\u003eC\u003c\/td\u003e\n\u003ctd style=\"width: 19.0183%; text-align: center;\"\u003eStaining Buffer\u003c\/td\u003e\n\u003ctd style=\"width: 11.0599%; text-align: center;\"\u003e25ml\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePubChem CID\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eGeneral Notes\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.
