General-purpose magnetic bead 48 samples( Board packaging ) rapid
virus extraction kit
Intend for Use:
This product does not need the process for sample pretreatment, and
the same reagent can simultaneously meet the extraction and
purification of DNA virus and RNA virus from serum, plasma and
culture medium of cotton swab. The processed products are used for
scientific research and testing.
Main Component:
Component | Specifications |
Preloaded deep hole plate | 12T/ board, 4 boards/box |
Protease K | 1.1mL/ tube, 1 tube/box |
Magnetic sleeve rod | 12 magnetic rod sleeve |
Storage Conditions and Expiry date:
Dry at room temperature (20 ~ 25℃), this product is valid for 12
months. Please refer to the product packaging label for the
production batch number.
Sample requirements:
1. Sample type: 200 μL of human whole blood or acellular body fluid (such as
serum, plasma, cerebrospinal fluid, nasal/pharyngeal swab, alveolar
lavage fluid, etc.)
2. Specimen Collection:
2.1 Anticoagulant whole blood: 2ml of venous blood was drawn with a disposable sterile syringe and
injected into the anticoagulant tube EDTA or sodium citrate.
Immediately, the glass tube was gently reversed and mixed for 5 to
10 times, so that the anticoagulant and venous blood were fully
mixed.
2.2 Serum: 2ml of venous blood was drawn with a disposable sterile syringe and
injected into a sterile dry glass tube. When the blood samples were
placed at room temperature (15-30 ℃) for 30-60 minutes or 4 ℃ for 2
hours, the serum could be completely agglutinated spontaneously, or
centrifuged at 1500 RPM for 5 minutes directly using a horizontal
centrifuge. The upper serum was absorbed and transferred to a 1.5ml
centrifuge tube for use.
2.3 Plasma: 2ml of venous blood was drawn with a disposable sterile
syringe and injected into an EDTA or sodium citrate anticoagulant
tube. Immediately, the glass tube was gently reversed and mixed for
5 to 10 times, so that the anticoagulant and venous blood were
fully mixed. After 5-10 minutes, the upper plasma could be
separated and transferred to a 1.5 mL centrifuge tube for reserve.
2.4 CEREBRO spinal fluid (CSF) : CSF is collected by lumbar
puncture, and can be obtained from cerebellar medulla cisterna or
lateral ventricle if necessary. Pressure measurement should be
performed by a physician after puncture. Cerebrospinal fluid
pressure can increase when any lesion increases the volume of brain
tissue or cerebrospinal fluid. Cerebrospinal fluid was collected in
sterile test tubes after pressure measurement.
2.5 Pharyngeal swab: Swab both pharyngeal tonsils and posterior
pharyngeal wall with two plastic rods with polypropylene fiber
heads. Dip the swab head into a tube containing 3ml sampling
solution, discard the tail, and tighten the tube cap. For highly
pathogenic respiratory tract infections, it is recommended to
inactivate them with water bath at 56 ℃ for 30min.
2.6 Nasal swab: Gently insert a plastic rod with a polypropylene
fiber head into the nasal canal at the nose and palate, stay for a
while, and then slowly rotate out. A plastic rod swab from another
polypropylene fiber head was taken from the other nostril in the
same manner. Dip the two swabs into the same tube containing 3ml
sample solution, discard the tail and tighten the tube cap. For
highly pathogenic respiratory tract infections, water bath at 56 ℃
for 30min is recommended for inactivation.
2.7 Alveolar irrigation fluid: after local anesthesia, insert the
bronchoscope through the mouth or nose through the pharynx into the
branch of the middle lobe of the right lung or the tongue segment
of the left lung, insert the top of the bronchial branch into the
opening, slowly add sterilized normal saline through the trachea
biopsy hole, 30~50 ml each time, the total amount is 100~250 ml,
should not exceed 300 mL. For highly pathogenic respiratory tract
infections, it is recommended to inactivate them with water bath at
56 ℃ for 30min.
3. Specimen storage and transportation: Specimens can be immediately used for testing, or stored in -70 ℃
or lower temperature for testing, storage period of 6 months,
should avoid repeated freezing and thawing. Specimens are
transported by cold chain.
4. Freezing and thawing requirements: quick freezing and thawing, avoid repeated freezing and thawing.
Extraction method:
1 Take out the reagent strip adaptor (K12), and insert the reagent
strip into the adaptor (the a-end of the reagent strip (the Angle
missing end) is in the same direction as the A-end of the adaptor).
2 Add 200 µL sample and 20μ L protease K to the first well at the A
end of the reagent strip.
3 Put the adapter into the base clip of the nucleic acid extraction
instrument, insert 12 magnetic rod sleeve into the clip slot of the
magnetic rod sleeve, open file management on the touch screen,
select "BMVF-K" program, and click Load - Run. Note: Place the
adapter in the base clamp with "H" on the left and "A" on the
right. If it is incorrectly placed, virus nucleic acid cannot be
obtained.
4 The extracted viral nucleic acid is stored in the "H" row. If it
is not used immediately, please transfer it to a 1.5ml sterile
nuclease free centrifuge tube and store it at -15~-25 ℃ or lower
temperature. Please store it at -70 ℃ for long-term storage.
