PCR DIRECT Extracting Transport Medium

제품 소개

PCR DIRECT Extracting Transport Medium(ETM)은 면봉 또는 타액 샘플 키트와 함께를 사용하여, 채취시점에 바이러스를 비활성화 하고 숙주 핵산(DNA 및 RNA)의 추출 안정성을 도모하기 위해 사용하는 제품입니다.

이 제품은 낮은 비용으로 증가된 감도를 제공하며, 추출된 핵산은 direct PCR/RT-qPCR 이나 bead/column-based kits를 사용한 후속 작업에 사용할 수 있습니다

Arcis의 PCR DIRECT 시약은 신속한 용해, 핵산 보호 및 잠재적인 PCR inhibitors의 차단을 위해 독점적인 One-Step™ chemistry 을 사용합니다.
면봉 또는 타액 샘플을 초고속으로 처리할 수 있으므로 연구자는 1번의 피펫팅으로도 direct PCR/RT-qPCR에 적합한 높은 감도와 재현성을 가진 결과물을 빠르게 얻을 수 있습니다.

제품특징

• 유해하지 않은 화학 물질로 폐기 비용 없음
• 상온에서 핵산 추출 수행-비용 절감
• 다른 장비나 시약 없이도 충분히 높은 감도 보장
• PCR inhibitors 불활성화
• 실온에서 최대 4 일간 RNA 안정

프로토콜

Swab Protocol

Swabs, immediately after collection, should be placed into sterile collection tubes containing aliquoted PCR DIRECT ETM.
We recommend preparing sample collection tubes ahead with 300 µl of PCR DIRECT ETM per tube.
For maximum sensitivity in direct RT-qPCR PCR, the reaction may be prepared with up to 50% sample by volume (e.g., up to 12.5 µl sample in a 25 µl reaction).
If a bead- or column-based isolation kit will be used, 200-300 µl of sample in PCR DIRECT ETM may be used for subsequent processing.

1. Collect oral or nasal swabs according to laboratory procedure.
2. Place swab head into PCR DIRECT ETM; swirl and rotate swab head against the tube wall 10 times to extract the maximum amount of liquid from the swab head.
3. Begin to remove the swab, press the swab head against the side of the collection tube to maximize the amount of prepared lysate.
4. Shake the tube vigorously at least ten times.
5. A sample is ready for transport and subsequent downstream molecular analysis or processing.

Note: the head of the swab should be fully submerged in a minimal volume of PCR DIRECT ETM. Complete immersion will ensure that the entire collected sample has been lysed. Minimizing the volume of PCR DIRECT ETM ensures the highest concentration of nucleic acids and supports direct PCR testing methods.

Saliva Protocol

For saliva samples, donors should be instructed not to consume food or drink, or use gum, toothpaste for at least 30 minutes prior to sample collection.
Saliva should not be mixed with other transport media or lysis reagents prior to the addition of the PCR DIRECT ETM as this may affect results.
This protocol may be adjusted for larger sample volumes by scaling the volume of PCR DIRECT ETM in proportion to the increase in the sample volume.
If a bead- or column-based isolation kit will be used, 200-400µl of sample in PCR DIRECT ETM may be used for subsequent processing.

1. Add 100 µl of saliva to a 1.5 ml low binding microtube.
2. Add 235 µl of PCR DIRECT ETM to the sample with the same pipette, mix ten (10) times.
3. Sample is ready for transport and subsequent downstream molecular analysis or processing.

Compare PCR DIRECT Extracting Transport Medium

Combines swab or saliva sample transport, viral inactivation without guanidinium, and RNA extraction in transit, while delivering increased sensitivity at a lower cost.
