Technical guides and protocols for lateral flow assays.
Robotic Process Automation (RPA) is transforming the Point of Care Testing (POCT) industry. By integrating RPA into the manufacturing of microfluidic PCR cartridges and TRF diagnostic strips, manufacturers can achieve unprecedented precision and scalability. RPA eliminates human error in reagent dispensing, optical module alignment, and quality control checks. As global healthcare demands faster and cheaper … Read more
Two-step PCR, omitting the traditional 72°C extension phase and merging it with the 55°C annealing phase, combined with microfluidic rapid thermal cycling, is setting a new gold standard for point-of-care infectious disease testing. This breakthrough technology means patients no longer wait days or hours for lab results. A Rapid Diagnostic Test (RDT) using two-step microfluidic … Read more
Global healthcare is demanding cheaper, faster diagnostics. By utilizing customized assay chemistry (like TRF) rather than stacking expensive optical bandpass filters, modern Chinese POCT manufacturers have reduced the BOM of optical detection modules by up to 90%. Furthermore, combining these advanced optics with microfluidic PCR cartridges allows for rapid thermal cycling without massive heatsinks or … Read more
Choosing the right IVD Reagents OEM/ODM partner in China can make or break your diagnostic product launch. Here is the ultimate 2026 checklist: 1. Check Certifications: Ensure they have NMPA, CE, or FDA compliance track records. 2. Microfluidic Expertise: Do they have in-house molding and microfluidic chip design capabilities? 3. Advanced Assays: Look for expertise … Read more
The main difference between Microfluidic PCR and Traditional PCR lies in thermal mass and speed. Microfluidic cartridges require microliter-level sample volumes, allowing TEC systems to ramp temperatures at 10°C/second. This reduces a standard 40-cycle amplification time from 2 hours to under 15 minutes. Here are the top 5 differences: 1. Speed: 15 minutes vs 2 … Read more
Time-Resolved Fluorescence (TRF) is an advanced optical detection technology that uses Lanthanide chelates (like Europium) to eliminate background autofluorescence. Unlike traditional fluorescent dyes (e.g., FAM) with nanosecond lifetimes, TRF offers microsecond emission, increasing the signal-to-noise ratio in POCT devices by over 100 times. In 2026, TRF is becoming the gold standard for rapid diagnostic tests … Read more
The Cost Challenge Vet clinics demand lower prices than human hospitals. How do you reduce COGS (Cost of Goods Sold) without sacrificing quality? Economical Materials By sourcing Due Bio Universal Strips directly from the manufacturer, you can cut raw material costs by 30%. Our strips are validated for Canine Parvovirus (CPV) and Heartworm assays.
The N-Gene Target While Spike (S) protein mutates, the Nucleocapsid (N) protein remains relatively stable, making it the ideal target for universal COVID-19 antigen tests. Matched Pairs We have validated specific antibody pairs that work seamlessly with our Universal Strips to detect Omicron, Delta, and other variants without cross-reactivity.
Why Does My Gold Turn Purple/Blue? If your red colloidal gold turns purple or blue, it has aggregated (clumped). This kills assay performance. Causes include incorrect pH during conjugation or insufficient blocking. Stabilization Ensure your gold nanoparticles are capped with a high-quality stabilizer like BSA or PEG. Due Bio provides pre-conjugated Gold-Antibody solutions and high-stability … Read more
