“MOLgen DNA Borrelia burgdorferi s.l. S1 Kit” is an assay kit for the detection of DNA of Borrelia burgdorferi sensu lato complex by Real-Time PCR.
“MOLgen DNA Borrelia burgdorferi s.l. S1 Kit” is intended for the detection of DNA of pathogenic to human Borrelia species of Borrelia burgdorferi sensu lato complex (B. afzelii, B. garinii, B. burgdorferi sensu stricto) using the method of real-time polymerase chain reaction (PCR) with fluorescence detection of amplified product.
The assay kit can be used in clinical practice for testing clinical material (cerebrospinal fluid, whole blood, blood serum, plasma, leukocyte blood fraction, biopsy material, tick suspensions). The results of PCR analysis are taken into account in complex diagnostics of disease.
The extraction of DNA can be performed using the “Molgen Universal Extraction Kit”.
When using NA extraction kits of other manufacturers it is highly recommended to use Internal Control sample (IC) manufactured by Adaltis.

Set 1 is validated for use with block-type PCR cyclers: iQ5 iCycler, CFX96, iQ iCycler (Bio-Rad, USA) and DT-96 (DNA-Technology, Russia).
Set 1 contains reagents requiredfor 48 tests, including control samples.
Real-time PCR is based on the detection of the fluorescence produced by a reporter molecule, which increases as the reaction proceeds. Reporter molecule is a dual-labeled DNA-probe that specifically binds to the target region of pathogens DNA. Fluorescence signal increases due to the separation of fluorescence dye and quencher by Taq DNA-polymerase exonuclease activity during amplification. PCR consists of repeated cycles: temperature denaturation of DNA, primer annealing and complementary chain synthesis.
Threshold cycle value (Ct) is a cycle number at which the fluorescence generated within a reaction crosses the threshold and the fluorescence signal rises significantly above the background. Increased signal is due to the use of a DNA hybridization probe that is specific for the given DNA sequence: it binds to one of the DNA strands in the course of reaction and provides additional specificity of the method. A DNA probe consists of a fluorescence dye at the 5’-end and a fluorescence quencher at the 3’-end that significantly reduces the fluorescence intensity. During the polymerase synthesis of the complementary strand, the probe is cleaved from the 5’-end due to the 5’-3’ nuclease activity of Taq DNA polymerase, the quencher and the dye become separated, thus increasing the fluorescence signal due to accumulation of the reaction product. The detected fluorescence intensity depends on initial quantity of pathogens DNA template in the sample.
The use of Internal Control sample (IC) prevents generation of false negative results associated with possible loss of DNA template during specimen preparation. IC indicates if PCR inhibitors occur in the reaction mixture. IC should be added to each sample (including control samples) prior to the DNA extraction procedure. Amplification and detection of IC influence neither sensitivity nor specificity of the target DNA PCR.
Note: Internal Control sample is added to the specimen during NA extraction step and is used throughout the whole process of NA extraction, amplification, detection.
