HLA-B27

Product catalog summary
Overview: The ViennaLab HLA-B27 StripAssay® is a diagnostic tool designed to confirm early diagnosis of ankylosing spondylitis and other spondyloarthropathies by detecting HLA-B27 subtypes. It offers a simple protocol that can be performed manually or automatically without the need for expensive lab equipment.
Key Features:
  • CE-labelled complete kit with DNA extraction included.
  • Detects all known HLA-B27 variants except a few rare alleles.
  • Based on reverse-hybridization of biotinylated PCR products.
  • Results are visible to the naked eye through an enzymatic color reaction.
Clinical Relevance: HLA-B27 is a genetic risk factor for diseases like ankylosing spondylitis, reactive arthritis, juvenile rheumatoid arthritis, and anterior uveitis. Ankylosing spondylitis affects 0.1-1% of the population, with a higher prevalence in males. Early diagnosis is crucial as symptoms can be nonspecific and diagnosis may take 5-10 years.
Procedure:
  1. Amplification: Multiplex PCR with biotin-labeling using a thermocycler.
  2. Hybridization: Conducted directly on the StripAssay® test strips using an incubator.
  3. Identification: Labeled products are detected by streptavidin-alkaline phosphatase, visible to the naked eye or via scanner and software.
Requirements: The assay requires a thermocycler, incubator, and optionally, software for result interpretation. It is designed to be easy, reliable, versatile, and affordable.
Conclusion: The ViennaLab HLA-B27 StripAssay® provides a straightforward and efficient method for diagnosing spondyloarthropathies, meeting customer needs with its simplicity and reliability.

u HLA-B27 StripAssayConfirm early diagnosis of ankylosing spondylitis by HLA-B27 genotypingAnkylosing spondylitis, reactive arthritis and HLA-B27 allele The allelic variant HLA-B27 is well known as genetic risk factor for spondyloarthropathies, such as ankylosing spondylitis (AS), reactive arthritis, juvenile rheumatoid arthritis, and anterior uveitis. Ankylosing spondylitis, also known as Morbus Bechterew, is the most prevalent spondyloarthropathy affecting 0.1 - 1% of the general population. Up to 96% of patients with AS and up to 80% of patients with reactive arthritis carry the HLA-B27 allele. Patients suffer from chronic pain and stiffness in the back and pelvis and, with progressing disease, often develop spinal fusion. The disease usually manifests between 15-30 years of age and is three times more prevalent in males than in females. Often a time period of 5-10 years elapses between early, nonspecific symptoms and a definite diagnosis. Differentiating between HLA-B27 positive and negative patients is therefore an important parameter for diagnosing spondyloarthropathies.
