Easy-to-use: the whole extraction process just needs 4 steps
with Viral Nucleic Acid Isolation Kit (Silica-Based Spin Column)
【PRODUCT NAME】
Viral RNA&DNA Extraction Kit
【METHOD】
Spin Column Method
Spin Column Viral DNA/RNA Extraction Kit utilizes a unique lysis buffer to lyse
virus and release DNA / RNA. The released DNA / RNA is effectively purified after
specifically binding to a silica-based spin column. It is suitable for isolating viral
DNA/RNA from up to 200 μl of plasma, serum, whole blood, tissue homogenate,
cell-free body fluid, nasopharyngeal or oropharyngeal aspirate/wash, bronchoalveolar
lavage fluid (BALF), tracheal aspirate, sputum, nasopharyngeal or oropharyngeal swab
and animal cell culture supernatant. The isolated DNA/RNA with high purity can be
applied in PCR, RT-PCR, qPCR, qRT-PCR, etc.
Using classic silica membrane adsorption technology and unique buffer system,
Virus DNA/RNA extraction Kits (spin column) can extract DNA/RNA from blood,
tissue, organs, environmental sample, saliva and nasal sample, and maximum
remove impurities protein and other organic compound impurities. The extracted
virus DNA/RNA can be directly used for downstream applications such as PCR,
RT-PCR, qPCR and qRT-PCR experiment.
Viral Nucleic Acid Isolation Kit (Silica-Based Spin Column) is specially designed for
efficient purification of viral RNA and viral DNA from cell-free samples such as
serum, plasma, urine, body fluids and the supernatant of viral infected cell cultures.
The sample is lysed by incubation with Lysis Solution. The Lysis Solution inactivates
RNases, ensuring protection of viral nucleic acids against degradation. The lysed
sample is transferred to a spin column where released viral nucleic acids immediately
bind to the silica-based filter in the presence of Binding Buffer. The remaining
contaminants are removed during three wash steps using Wash Buffer, whereas
pure nucleic acids remain bound to the membrane. Pure viral nucleic acids are
released from the spin column filter using Elution Buffer. The purified nucleic
acids are ready-for-use in subsequent downstream applications of molecular biology.
【APPLICATIONS】
sample, saliva, nasal liquid and swab sample.
【FEATURES】
Viral RNA&DNA Extraction Kit (Spin column) The kit utilizes a silica-based membrane
technology in the form of a convenient spin column. Viral nucleic acids from lysed
samples bind to the column membrane while impurities are effectively removed
during subsequent washing and centrifugation steps. Ready-to-use nucleic acids
are eluted from the column. The kit allows simplified isolation of viral RNA from
cell-free body fluids with a fast spin-column format. No phenol/chloroform extraction
is required. Viral RNA binds specifically to the silica membrane while contaminants
are removed in the flow-through. PCR inhibitors such as divalent cations and proteins
are completely removed in two efficient wash steps, leaving pure viral RNA to be
eluted in RNase-free water. Purified RNA is ready to use in RT-PCR, Northern
blotting or other downstream applications.
• The operation process is simple, quick, and non-toxic
• High purity DNA/RNA, stable quality

【INTENDED USE】
This kit is used to extract DNA/RNA from plasma, serum, animal tissues, body fluids
and other samples. The sample is processed by the lysis solution to release DNA/RNA.
At the same time, a special polymer membrane material is used to selectively adsorb
viral DNA/RNA, and then after washing and elution operations, high-purity viral
DNA/RNA can be obtained. The nucleic acid extracted by this kit can be used for
Real-time PCR, Nothern Blot, Blotting Hybridization, cDNA Library Construction.
The kit can be used for both research purposes and in vitro diagnosis (IVD) and
is validated for COVID-19 diagnosis.
