靶向卵巢癌的納米脂質(zhì)微泡造影劑的制備及體外尋靶研究
[Abstract]:Purpose: preparing a novel nano lipid micro-bubble contrast agent for targeting ovarian cancer, identifying physicochemical properties and targeting of ovarian cancer cells, The foundation. Method: 1. A certain proportion of dipalmitate, choline (DPPC), streptavidin (DSPE-NHS-Bioin) and glycerol, PBS, etc. were mixed evenly, and the non-target was prepared by freeze drying and mechanical oscillation. The dispersion, homogeneity and Zeta of microvesicle were observed under light microscope. The size range of the particle size is detected by a detector. 3. A certain proportion of the dipalmitate, the phospholipid, the choline (DPPC), the Biotin dipalmitate and the ethanolamine (DSPE-NHS-Bioin) and the glycerol, the PBS and the like are uniformly mixed, the freeze drying method and the mechanical oscillation method are adopted, biotin-avidin-biotin bridging method is used to prepare non-targeted nano-lipid micro-bubble contrast agent, and biotin-induced luteinizing hormone releasing hormone (LAMP) antibody is connected with non-targeting nano lipid micro-bubble contrast agent to prepare egg The morphology, homogeneity and concentration of microvesicles and preservation time at room temperature were observed under light microscope. Zet a Detector detects particle size range, surface potential. 5. Flow cytometry respectively detects the non-targeted nano-lipid micro-bubble building Contrast ratio of contrast agent and nano-lipid micro-bubble contrast agent to two anti-binding agents: 6. Under light microscope, it is observed to target nano-lipid. Microbubble contrast agent binding to human ovarian cancer OVCAR-3 cells. 7. Pre-use the biotin-labeled antibody to bind to human ovarian cancer OVCAR-3 cells, and then observe the target again. rice lipoid Results: 1. Non-targeting lipid micro-bubble contrast agent is a milky white suspension liquid, 400 times light microscope observation and Zeta detector detect mechanical oscillation 60s, 90s, 120s, micro bubble distribution is uniform, no agglomeration, the appearance of single micro bubble is round, the particle size range is 329-1008, respectively. nm, 295 ~ 468nm, 369 ~ 618nm, 157 ~ 268nm, 400 times light microscope and observation of Zeta detector to detect mechanical oscillation 150s, micro bubble The distribution is uneven, no agglomeration, the appearance of a single micro bubble is round, the particle size range is 60-896nm. The shadow agent and the target nano lipid micro-bubble contrast agent microvesicle are successfully prepared, the appearance of the two micro bubbles is round, the distribution is uniform, and the detection particle size range of the Zeta detector is 295-468nm and 369-618nm, respectively, It is focused on the size of 360nm and 508nm. The difference in economics (P <0.05). Under light microscope, the micro-bubble shape was dispersed uniformly and the preservation time of room temperature was long. The two micro-bubble potentials were-14. 6mV. 7d, there was no statistical difference between the physical and chemical properties of the targeting Naomi microvesicles (P> 0.05). The combination rate of non-targeted nano-lipid micro-bubble contrast agent and target nano-lipid micro-bubble contrast agent was 0. 83%, 75.6%, respectively. 5. There is a rosette-like structure around OVCAR-3 cells under light microscope. 6 Under light microscope, the avidin preblocking OVCAR-3 cells could not be combined with the targeted nano-lipid micro-bubble contrast agent. Conclusion: 1 mechanical oscillation 90s is the best time for the preparation of non-target lipid micro-bubble contrast agent, that is, to prepare the non-targeting nano-lipid micro-bubble mechanical oscillation time. The targeted ovaries can be successfully prepared by freeze drying, mechanical oscillation and biotin-avidin bridging. The nano-lipid micro-bubble contrast agent of the cancer is small in particle size and high in stability. 3. Targeted nano-lipid micro-bubble contrast agent can target people in vitro Ovarian cancer OVCAR-3 cells. 4. Saturated ovaries blocked by Biotin Antibody
