This section instead of the date of implementation of the GB/T 18448.2-2001. This part of the main technical differences compared with the GB/T 18448.2-2001 as follows. a) increase Toxoplasma enzyme linked immunosorbent assay (ELISA) and immunohistochemical staining test (IEA), the PCR detection methods listed in Appendix Content, retaining indirect hemagglutination test (IHA) as one of the recommended methods; b) the required detection method, "Materials and Reagents" and "detection step" described separately. Appendix A of this section is normative appendix. This part of the National Standardization Technical Committee of experimental animals and focal points. This section drafted by.

1 Scope

GB/T 18448 provisions of this part of the experimental animals Toxoplasma gondii detection methods and reagents. This section applies to mice, rats, hamsters, guinea pigs, rabbits, dogs and monkeys and other animals Toxoplasma gondii detection. Principle 2 According to the principles of immunology, Toxoplasma antigen detection using animal serum antibody detection of Toxoplasma gondii.

3 Reagents and equipment

3.1 Reagents 3.1.1 ELISA antigen 3.1.1.1 Specific Antigen Toxoplasma gondii (RH strain) tachyzoites inoculated intraperitoneally cleaning stage above mice (KM, ICR, BALB/c, etc. can be), after the 3d ~ 5d, to Sterile saline lavage of the abdominal cavity of mice vaccinated, mouse peritoneal fluid was collected containing the worm, 3000r/min centrifugal 10min, the precipitate, PBS three times. Add appropriate amount of distilled water to precipitate five times repeated freezing and thawing, or ultrasonic treatment, 10000r/min centrifugal 30min, take on Serum. Supernatant Sephadex G200 gel (column diameter × column height. 1.5cm × 60cm), a flow rate of 0.2mL/min. each Collection tube about 2mL. We collected a total of 60 or more. Each collection tube protein absorbance values \u200b\u200bwere measured at 280nm under. Isolation of pure After technology, the emergence of two protein peaks; the first peak of the tubes were combined, namely Toxoplasma-specific antigen (also known as Toxoplasma gondii soluble antigen). 3.1.1.2 normal antigen Sterile saline injection cleaning stage above mice (mice with an antigen preparation of the same species or strain) intraperitoneal, after 3d ~ 5d, to Sterile saline is injected in murine peritoneal lavage collected mouse peritoneal fluid, 3000r/min centrifugal 10min, the precipitate, PBS washed 3 times. Add appropriate amount of distilled water to precipitate five times repeated freezing and thawing, or ultrasonic treatment, 10000r/min centrifugal 30min, the supernatant is normal antigen. 3.1.2 antigen sheet Toxoplasma gondii RH tachyzoites inoculated intraperitoneally cleaning stage above mice (KM, ICR, BALB/c, etc. can be), 3d ~ 5d at the rear Dead, collect worms, trypsin, to a certain concentration smear, fully dry after cold acetone fixed, -20 ℃ preservation. 3.1.3 Toxoplasma antigen-sensitized sheep red blood cells The tannic acid was reacted with a certain concentration of sheep red blood cells, red blood cells formed tanning, then, with Toxoplasma gondii soluble antigen in a suitable strip Member under tanning sensitized red blood cells, made of Toxoplasma antigen-sensitized sheep red blood cells. 3.1.4 normal sheep red blood cells. 3.1.5 positive control serum Naturally infected with Toxoplasma corresponding animal antibody positive serum or serum Toxoplasma gondii. 3.1.6 negative control serum No confirmed toxoplasmosis animal serum. 3.1.7 conjugate Horseradish peroxidase-labeled anti-mouse, rat, hamster, guinea pigs, rabbits, dogs and monkeys IgG antibody; or horseradish peroxidase-labeled Portugal Aureus protein A (SPA). 3.1.8 fluorescein conjugates Isothiocyanate hydrogen acid fluorescein-labeled anti-mouse, rat, hamster, guinea pigs, rabbits, dogs and monkeys IgG antibodies.
