Southern Blot

Southern Blot

Agarose gel electrophoresis is very useful in separating DNA fragments by size. Running a DNA ladder containing fragments of the known length alongside the sample helps determine the approximate length of the sample DNA fragments. However, additional steps are needed to verify the sequence identity of the sample DNA fragments.
Denatured DNA fragments must be transferred onto a carrier membrane from the gel to make it accessible to a probe - a small ssDNA fragment complementary to the target DNA...

Labeling DNA Probes

Labeling DNA Probes

DNA probes are fragments of DNA labeled with a reporter tag to enable their detection or purification. The resulting labeled DNA probes can then hybridize to target nucleic acid sequences through complementary base-pairing, and may be used to recover or identify these regions.
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...

Blood Typing

Blood Typing

Understanding an individual's blood group is a critical component of transfusion medicine. It ensures compatibility in blood transfusions, organ transplants, and even during pregnancy. Determining these blood groups involves the ABO and Rh blood typing systems, utilizing specific antigens and corresponding anti-sera to identify an individual's blood type.
Antigens are protein molecules that reside on the surface of red blood cells (RBCs). The ABO and Rh blood typing systems target antigens A,...

Western Blotting

Western Blotting

Western blotting is an analytical technique for protein identification. It has various applications in immunology and medicine, including detecting diseases like bovine spongiform encephalopathy, mad cow disease, and human and feline immunodeficiency virus from biological samples.
The technique begins with separating proteins from the sample using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), followed by protein transfer, immunoblotting, and finally, protein detection.

Sports Science
Biochemistry
Genetics

Background:

Homologous blood doping enhances oxygen-carrying capacity but poses health risks.
Despite the rise of rhEPO, athletes may still use blood transfusions for performance enhancement.
Current detection methods, like flow cytometry, identify mixed red blood cell populations.

Purpose of the Study:

To propose and validate a novel qPCR genotyping assay for detecting homologous blood doping.
To assess the feasibility of detecting donor cells even when leukocyte DNA is significantly depleted.

Main Methods:

Development of high-resolution qPCR-based genotyping assays.
Testing the sensitivity of assays to detect low levels of donor DNA in recipient blood.
Analysis of test specificity and potential ethical considerations.

Main Results:

Demonstrated that qPCR genotyping assays can detect second cell populations indicative of homologous blood doping.
Showed assay effectiveness even when donor leukocytes were depleted by 99% of their DNA.
Discussed the implications for test sensitivity and specificity.

Conclusions:

qPCR genotyping offers a promising alternative or complementary method for detecting homologous blood doping.
This approach could enhance anti-doping efforts by identifying blood transfusions even with minimal DNA evidence.
Ethical considerations regarding athlete genotype usage in anti-doping require careful deliberation.
