For this, in the gel cell, separate fractions are used.
- Example 2 Gel-forming mixture, at 37 ° ⁇ and containing
- Bacterial cultures isolated from patients are primarily grown on a solid medium. All the interested parts remove the lugs and insert them into the separate parts with the gel-forming solution, carefully suspend.
- the automatic microprocessor selects 0.1–0.2 microns from each appliance and, in a separate order, is applied to the appliance, it is free of charge. They are used in parishes ⁇ a (see Example 1).
- the number of manufactured products is determined by the number of antibiotics, the sensitivity to inadvertent process and the inability to process it.
- Each microscope uses a droplet (which covers all the elements) of the liquid medium containing a separate concentration of antigens.
- the cameras are placed in a humid chamber and incubated for 3-4 hours at 37 ° ⁇ .
- the recording of the results is carried out as follows. Cleaners wash the water, place a microcircuit (400 x ) and evaluate the presence of seeds in each microcircuit cell (Fig. 5 ⁇ ). The absence of cells in the cell (Fig. 5B) indicates that this antibiotic is effective in this culture.
