Introduction

At 2 a.m. in an emergency clinical laboratory, a blood sample is waiting for pathogen identification. At a border inspection site, a batch of imported meat products requires rapid pathogen screening. On a livestock farm, sudden deaths among poultry and animals urgently call for ruling out highly pathogenic infections. Time is the key to diagnosis—and the critical window for prevention and control.

Are you still troubled by cumbersome nucleic acid extraction steps? Still worried that inhibitors in complex samples may compromise your results? Is there a way to bypass time-consuming extraction, directly tackle complex matrices, and significantly improve efficiency? A revolution in the traditional qPCR workflow has arrived—a fully premixed, inhibitor-resistant Direct PCR Master Mix designed for simplicity, speed, and reliability.

Pain Points: Efficiency and Reliability Bottlenecks in Traditional qPCR

1. Sample Loss

Multiple centrifugation and transfer steps during extraction are not only labor-intensive but may also lead to the loss of precious low-abundance samples and increase the risk of cross-contamination.

2. Inhibitor Interference

Complex samples such as blood, sputum, and feces often contain residual inhibitors that interfere with polymerase activity, resulting in reduced amplification efficiency, abnormal curves, or even false-negative results.

3. High Time Cost

The conventional combination of “nucleic acid extraction + PCR amplification” typically takes 1–2 hours. For high-throughput testing or urgent diagnostics, this workflow has become a major bottleneck to speed.

Breaking the Barrier: Inhibitor-Resistant Direct PCR Master Mix for True “One-Step” Detection

To meet the demand for rapid, accurate, and robust on-site testing, Hzymes introduces a new-generation inhibitor-resistant Direct PCR Master Mix. This is not just a reagent upgrade, but a true transformation of the testing workflow. Four core advantages directly address long-standing challenges.

Advantage 1: Extraction-Free Direct Amplification

For a wide range of sample types—including blood, sputum, oral swabs, viral transport media, and feces—no tedious nucleic acid extraction is required. After simple lysis or heat treatment, a small amount of supernatant can be directly added to the PCR reaction. What once took hours for “extraction + amplification” can now be completed in under 30 minutes.

Advantage 2: Exceptional Inhibitor Resistance for Complex Matrices

Through targeted enzyme engineering and an optimized inhibitor-resistant buffer system, the Master Mix effectively overcomes common inhibitors found in complex samples, maintaining high amplification efficiency and sensitivity to ensure accurate and reproducible results.

Advantage 3: Fully Premixed Primers and Probes for Ultra-Simple Operation

The product supports advance premixing of primers and probes with the Master Mix. Users only need to add the processed sample template to start the reaction. This streamlined workflow allows even non-specialists to perform testing with ease, enabling standardized detection and making it ideal for high-throughput screening, routine monitoring, and rapid diagnostics.

Advantage 4: Fast Cycling Programs with Results in 30 Minutes

While traditional qPCR assays often require 1–2 hours, the inhibitor-resistant Direct PCR Master Mix—enabled by engineered enzymes and optimized reaction systems—can complete amplification within 30 minutes, dramatically improving turnaround time.

Performance Evaluation Data

01. Direct Amplification Performance

Direct amplification of whole blood and fecal samples shows that Hzymes reagents outperform competing products from Supplier A and Supplier B.

A. Whole blood samples diluted 10× with TE buffer; 5 μL used as template for PCR.
B. Fecal samples pretreated with lysis buffer; 5 μL of supernatant used as template for PCR.

02. Inhibitor Resistance Performance

Compared with Supplier A and Supplier B, Hzymes demonstrates stronger resistance to humic acid and heme.

C. Extracted nucleic acids diluted with 100 ng/μL humic acid solution; 5 μL used as template for PCR.
D. Extracted nucleic acids diluted with 500 μM heme solution; 5 μL used as template for PCR.

03. Stability of Premixed Primers and Probes

After premixing with primers and probes and incubating at 37 °C for 10 days, amplification performance remains stable compared with non-incubated controls.
