Influenza, commonly known as the flu, is a respiratory illness that is caused by influenza viruses. Influenza A and B viruses are among the most common causes of seasonal flu outbreaks worldwide, leading to significant health burdens every year. According to WHO, the annual epidemics result in several million cases of severe illnesses and approximately 250,000 to 500,000 deaths per year worldwide. Rapid and accurate detection is crucial for timely treatment, outbreak control, and public health response.
Diagnostic testing for influenza spans a range of technologies-from viral isolation to immunodiagnostic and molecular diagnostic methods. Immunodiagnostic tests, especially rapid influenza diagnostic tests (RIDTs), remain a preferred choice due to their ease of use, cost-effectiveness, and fast turnaround. However, test sensitivity can vary widely depending on the antibodies used. Hytest Influenza A and B antibody products are designed to meet the demand for high-sensitivity and high-specificity assay development.
1. Diverse Origins & Versatile Production
Our antibodies are derived from a range of animal sources and produced using various methods, ensuring broad platform compatibility and flexibility for your assay development needs.
2. Proven High Sensitivity
All antibodies are developed to deliver exceptional sensitivity. A standout example is our top-performing pair – FA32 (capture) and FA17 (detection) from Cat. # 3IN5 – which has achieved a sensitivity level of 0.5 ng/ml against recombinant Influenza A nucleoprotein (NP) antigen on a lateral flow (LF) platform.
Notably, FA17 offers superior detector performance, combining high sensitivity with no non-specific binding - making it a reliable choice for detection.
3. Broad Strain Recognition
Hytest Influenza A antibodies demonstrate broad specificity, allowing for effective detection across multiple Influenza A virus strains.
4. Exceptional Specificity
No cross-reactivity with Influenza B virus (≤ 0.1%)
No cross-reactivity with SARS-CoV-2-NP (<0.05%)
