Definitions
- Figure 1 p.8 shows a schematic representation of the sand wipe hybridization method.
- the capture probe 1 is labeled with biotin 4; binds to magnetic beads 7 coated with streptavidin 7.
- detection is carried out with alkaline phosphatase 6 which is attached to the digoxigenin labeled detection probe 2 binds via Anti DIG Fab fragments.
- the detection of the amplified fluorescence signal can be quantified by a fluorescence reader. Another possibility of detection is the detection of the activity of the alkaline phosphatase by electrochemical sensors.
- the 16S ribosomal DNA was amplified from the total DNA of various Legionella species using the fD1 and rP2 universal primers for the 16SrDNA by means of PCR.
- the promoter region of the T7 polymerase was contained in the fD1.
- 166Sr RNA transcribed in vitro was prepared from the corresponding PCR products from Legionella (16SrDN A) using the DIG RNA LabelingKit (SP6 / T7) (Röche) or the MAXIscript-Kit / Ambion.
