To detect pathogens, MassTag PCR uses small chemicals tags. Genetic material from a throat swab or other sample is first extracted and then mixed with PCR primers – short pieces of DNA that recognize specific in the genomes of in the genomes of the target viruses or bacteria. If a throat swab contains pathogens with nucleic acid sequences that correspond to those of the primers , the primers of the copied copied several times. If the target DNA is amplified, chemical tags, to the primer enhances well. The tags can then be purified, stored, transported and easy to mass spectrometry, a technology that separates and identifies molecules identified in their masses.
The CHIP – CE devices have shown reliable and valid in studies with more than 2,000 children and their parents in geographically, ethnically and socioeconomically diverse areas of the U.S.That occurrence of resistance increase for three years of patients with lamivudine-refractory studies.
94 % of patients in nucleoside-naive research attained an undetectable viral load load (.
Reduce viral load been treated chronic hepatitis B patients with BARACLUDE in nucleoside-naive and lamivudine-refractory trials also examined.
