Embodiment 1
[0039] Example 1 Construction of pCMV-MOR1·EF1-copGFP plasmid
[0040] Ligase site EcoR I and not 1, the human mu opioid receptor MOR1 gene is cloned under the CMV promoter of the lentiviral expression vector pCDH-CMV-MCS-EF1-copGFP, and the eukaryotic expression plasmid pCMV-MOR1·EF1-copGFP is constructed (such as figure 1 shown).
Embodiment 2
[0041] Example 2 Establishment of MOR1·copGFP / 293 stable cell line and copGFP / 293 stable cell line
[0042] The pCMV-MOR1·EF1-copGFP plasmid, pH1 plasmid, and pH2 plasmid were co-transfected into lentiviral packaging line cell 293V to prepare CMV-MOR1·EF1-copGFP lentivirus, and transfected into HEK293 cells, and clones were picked under a fluorescent microscope to establish MOR1·copGFP / 293 stably transfected cell line. Specific steps are as follows:
[0043] 1) Preparation of packaging line cells: One day before transfection, use DMEM-H complete culture medium (containing 10% FBS and 100U / ml penicillin, 100μg / ml streptomycin double antibody) to make lentiviral packaging line cells 293V into 1 ×10 6 / ml concentration, and inoculated in a D19cm cell culture dish, 37°C, 5% CO 2 Incubate overnight.
[0044] 2) Transfection: When the cells in the culture dish grow to 70%-80% confluence, use PEI transfection reagent (refer to its standard transfection operation procedure) to inf...
Embodiment 3
[0051] Example 3 Application of Universal Detection Kit for Opioid Active Substances
[0052] The universal detection kit for opioid active substances developed based on the technical solution of the present invention can be applied to the detection of various samples containing opioid active substances. In this embodiment, we take the hair of a person taking morphine as an example. Specific steps are as follows:
[0053] 1) Hair sample processing: Take 5 hair samples of morphine addicts and 5 hair samples of normal people without smoking history, and the numbers are shown in Table 1.
[0054]
[0055] Cut the hair sample within 3cm of the hair root at 20mg / part, cut it into pieces, put it into a 5ml EP tube, add 2ml of HBSS buffer solution (pH7.4) containing 1% keratinase, add a small amount of zirconium beads and quartz sand, and crush it Shake and pulverize for 1 minute to obtain corresponding sample liquids.
[0056] 2) Cell preparation: mix 5×10 cells one day in adv...
