Assay principle
The kit is based on allele-specific real-time PCR using hydrolysis probe technology. Detection is performed in a duplex format, allowing simultaneous monitoring of the target signal and an internal control. HLA-B27 detection is based on two independent HLA-B27-specific target regions within the HLA-B gene (Exon 2 and Exon 3). By targeting both regions in parallel, assay robustness is increased and the risk of false-negative results caused by rare sequence variants is reduced. The HLA-B27 signal is detected in the FAM channel. The internal control is detected in the ROX channel and ensures reliable identification of PCR inhibition or insufficient DNA release. Direct PCR from whole blood (no DNA extraction required) The kit is optimized for direct use of EDTA whole blood, enabling a simplified workflow without mandatory DNA extraction. A simple dilution of the blood sample is required. Optional is a short heat pre-treatment step (e.g., 95 °C for 10 minutes) to lyse leukocytes and release DNA. Alternatively, purified genomic DNA can be used as PCR input material.
Workflow (overview)
1. Dilute EDTA whole blood
2. Heat pre-treatment (recommended)
3. Set up the qPCR reaction
4. Run real-time PCR
5. Qualitative analysis based on amplification curves
Result interpretation
Positive: Amplification in the FAM channel (HLA-B27) with a valid internal control signal in the ROX channel.
Negative: No FAM signal, but clear amplification of the internal control in the ROX channel.
Invalid: No internal control signal (indicating PCR inhibition or incorrect sample preparation).
Cycler compatibility
A real-time PCR instrument with at least two detection channels is required: FAM and ROX.
The assay is compatible with common qPCR platforms supporting these channels.
Note
This kit is intended for screening applications. In rare cases, sequence variations of specific HLA-B27 subtypes may affect amplification performance. In case of discrepant results or specific populations, confirmatory subtyping may be recommended.
