HIV Stripassay Kit

Short description

The Viennalab HIV Strip Assay is an innovative diagnostic tool that uses the principle of reverse-hybridization to detect and differentiate between HIV-1 and HIV-2 subtypes. It involves two key steps: the amplification of targeted viral RNA regions via reverse transcription PCR, and a hybridization process where the amplified DNA is hybridized with specific oligonucleotide probes on a strip.

This assay is crucial for both patient care and epidemiological research, as it informs personalized therapeutic strategies and provides insights into the prevalence and spread of different HIV subtypes.

Product highlights

  • Significantly improved treatment and reduced AIDS-related mortality
  • Allelic variants gives better outcomes of HAART.
  • Better guidance of HIV therapy.
  • The PGX-HIV StripAssay® can identify genetic variants

Specifications of the HIV Stripassay Kit

Like other strip assays from Viennalab, the HIV Strip Assay is grounded in the principle of reverse-hybridization. It focuses on detecting HIV-1 and HIV-2 genotypes, leveraging the amplification of targeted genetic sequences through Polymerase Chain Reaction (PCR), followed by a hybridization process.

The first stage involves the amplification of the relevant viral RNA region via reverse transcription PCR. This process produces multiple copies of the DNA, enhancing the signal for subsequent detection. The second stage is hybridization, where the amplified DNA is denatured into single strands. These single strands are then hybridized with specific oligonucleotide probes that are immobilized on a strip.

The Viennalab HIV Strip Assay is designed to accurately identify multiple subtypes of HIV-1 and HIV-2, which can provide a comprehensive profile of the infecting viral strain. Detecting the subtype of HIV infection is critical for both patient care and epidemiological research. In a clinical setting, this assay can help healthcare professionals devise personalized therapeutic strategies, considering the different subtypes’ varying responses to antiretroviral therapies.

Furthermore, in an epidemiological context, the assay can deliver valuable insights into the prevalence and spread of different HIV subtypes, which can inform public health interventions and research into new treatment options.

The Viennalab HIV Strip Assay stands as a groundbreaking development in the sphere of infectious disease diagnostics. By enabling swift, cost-effective, and highly accurate determination of HIV subtypes, it provides a foundation for more personalized medical interventions and is a crucial tool for understanding the disease’s epidemiology. For lab technicians and scientists, the use of such advanced technologies is essential for maintaining the quality and accuracy of diagnostic testing, underscoring the value of their work, and driving progress in disease management.

Components of the HIV Stripassay Kit
  1. StripAssay: A test strip containing immobilized antigens from HIV-1 and HIV-2, including gp41, gp36, gp120, and gp36/41 for the detection of HIV-specific antibodies.
  2. Conjugate: A solution containing anti-human IgG antibodies conjugated to horseradish peroxidase (HRP) that bind to the HIV-specific antibodies on the StripAssay.
  3. Substrate: A solution containing a chromogenic substrate for HRP that produces a color reaction upon cleavage by the enzyme.
  4. Stop Solution: A solution used to stop the enzymatic reaction and stabilize the color reaction.
  5. Positive Control Serum: A serum containing known amounts of HIV-specific antibodies that is included as a positive control for the assay.
  6. Negative Control Serum: A serum from an HIV-negative individual that is included as a negative control for the assay.
  7. Sample Diluent: A solution used to dilute the patient’s serum or plasma sample before testing.
  8. Wash Buffer: A solution used to wash the test strip to remove any unbound conjugate or sample components.

The kit also includes instructions for use, as well as a protocol for the detection of HIV-specific antibodies using the StripAssay format.
