Viral extraction is made efficient and reliable with the TRUPCR® Total Viral Nucleic Acid Extraction Kit, designed for the simultaneous purification of viral DNA and RNA from plasma, serum, and other cell-free fluids. The kit utilizes silica column technology and a proprietary buffer system, including carrier RNA, to improve nucleic acid recovery—especially from low-titer samples. With a four-step workflow (lysis, binding, washing, and elution), it eliminates the need for organic solvents and delivers high-quality, PCR-ready viral nucleic acids in under 45 minutes. The kit is compatible with a wide range of TRUPCR® viral load assays, including HIV, HCV, HBV, and more. This solution is ideal for clinical labs, research facilities, and molecular diagnostics professionals needing consistent results in viral nucleic acid extraction.
Viral extraction is the process of isolating viral nucleic acids—either RNA or DNA—from biological fluids such as plasma, serum, or urine. These purified nucleic acids are essential for accurate detection and quantification of viral infections using PCR or RT-PCR. The TRUPCR® kit simplifies this process into four efficient steps, providing high-quality nucleic acids suitable for downstream applications like qPCR, sequencing, or genotyping.
Viral DNA and RNA serve as the genetic fingerprints of viral pathogens. Extracting them efficiently is crucial for early detection and accurate monitoring of viral infections such as HIV, HBV, HCV, CMV, Dengue, and others. Poor extraction can result in false negatives or weak amplification signals. The TRUPCR® Viral Extraction Kit ensures reproducible results by including carrier RNA to maximize recovery and eliminate common inhibitors such as proteins and salts.
This kit is built around a silica column-based method and is optimized for use with sample volumes ranging from 200 µl to 1 ml. It uses a chaotropic salt-based lysis buffer to inactivate RNases and release viral nucleic acids. Carrier RNA is added to the lysis step to enhance nucleic acid binding, especially in low-titer samples. Ethanol-based wash steps remove contaminants, and a final elution step delivers purified viral RNA or DNA in 40–50 µl. The entire process can be completed in less than 45 minutes.
The TRUPCR® Viral Extraction Kit is compatible with:
TRUPCR® HIV Viral Load Kit
TRUPCR® HBV Viral Load Kit
TRUPCR® HCV Viral Load Kit
TRUPCR® CMV, HSV, Dengue, and Chikungunya Kits
The workflow includes:
Lysis – Viral particles are broken down with BAV1 lysis buffer containing guanidine isothiocyanate
Binding – DNA/RNA binds selectively to the silica membrane in the presence of ethanol
Washing – Two steps with BAW1 and BAW2 buffers remove inhibitors and contaminants
Elution – Nucleic acids are eluted in RNase/DNase-free buffer or water
This streamlined workflow reduces the risk of cross-contamination and is designed for labs without automation infrastructure but needing consistent, reliable extractions.
The Viral Extraction Kit supports a broad range of diagnostic and research use cases:
Viral load monitoring for HIV, HBV, and HCV
Detection of emerging or re-emerging viral infections like CMV or Dengue
Real-time PCR-based identification of viral RNA and DNA in clinical surveillance
Genomic analysis for epidemiological tracking and outbreak response
With its reliable yield, compatibility with leading PCR platforms, and user-friendly format, the TRUPCR® kit is ideal for clinical labs, public health institutions, and academic research settings.
