Streck Cell-Free RNA BCT® 血漿游離RNA保存管
產品英文名稱：Streck Cell-Free RNA BCT® BLOOD COLLECTION TUBE
產品中文名稱：Streck 游離RNA保存管，血漿血清
產品概述 Streck Cell-Free RNA BCT®游離RNA保存管含有一種防腐劑，它能穩定有核血細胞，防止細胞RNA的釋放，是保護游離循環RNA的一種血液收集管，用于采集、運輸和穩定血液游離RNA。
參數
采血量 10mL
游離RNA穩定性 18-25℃，7天
保質期 24個月
穩定性
游離RNA室溫下zui高能穩定7天
沒裝樣本的采血管保質期有24個月
應用
回復高質量的游離RNA適用于臨床研究、藥物開發和診斷分析發展中的靶向PCR。
概要和原理
1樣本處理、運輸和后期處理導致有核血細胞的細胞溶解和RNA的釋放會影響cf-RNA的準確分析。此外，由于核酸酶造成RNA降解也會造成影響。
2 Streck 游離RNA保存管中的防腐劑能穩定有核血細胞,防止細胞RNA的釋放和抑制核酸酶造成cf-RNA的降解，從而有利于cf-RNA和細胞RNA的穩定。
3 Streck 游離RNA保存管加強對cf-RNA和細胞RNA的純化、檢測和分析。管中的樣本在18 °C - 25 °C能穩定在7天，以便于樣本收集、傳輸和存儲。
成份
包含抗凝劑K3EDTA，核酶抑制劑，代謝抑制劑和細胞防腐劑。試劑呈現紅色是正常現象。
注意事項
1采集樣本后不能冷凍，否則可能破裂。
2超過效期請不要使用。
3不要將注射進病人體內。
4試劑成份是固定的，不要稀釋或者添加其他成份。
5樣本過少或者過多都可能對zui后的分析結果造成不好的影響。
注意 a.玻璃有破碎的可能性;在處理過程中應采取預防措施。
b.所有與它們接觸的所有生物標本和材料都被認為是生物危害，按照生物安全法規處理，避免與皮膚和粘膜接觸。
c.產品應與傳染性醫療廢物一起處置。
d.要么通過輕輕的搖擺瓶塞或者邊扭動邊拉拽的方式打開瓶塞。用于瓶塞拆卸的“拇指滾動”程序不推薦，可能導致管破裂和損傷。
INSTRUCTIONS FOR USE
Cell-Free RNA BCT® is a direct-draw whole blood collection tube intended for collection, stabilization and transportation of cell-free plasma RNA. Cell-Free RNA BCT also stabilizes and preserves cellular RNA in white blood cells. This product has not been cleared by the U.S. Food and Drug Administration for In Vitro Diagnostic Use. The product is For Research Use Only. Not for use in diagnostic procedures.
SUMMARY AND PRINCIPLES
Accurate analysis of cf-RNA can be compromised by sample handling, shipping and processing, causing lysis of nucleated blood cells and subsequent release of cellular RNA. Additionally, degradation of cf-RNA due to nuclease activity can be problematic.
The preservative reagent contained in Streck’s Cell-Free RNA BCT stabilizes nucleated blood cells, preventing the release of cellular RNA, and inhibits nuclease mediated degradation of cf-RNA, contributing to the overall stabilization of both cfRNA1,2,3 and cellular RNA.4
Cell-Free RNA BCT enhances purification, detection and analysis of cf-RNA and cellular RNA. Samples collected in Cell-Free RNA BCT are stable for up to 7 days at temperatures between 18 °C to 25 °C, allowing convenient sample collection, transport and storage.
REAGENTS
Cell-Free RNA BCT contains the anticoagulant K3 EDTA, nuclease inhibitors, metabolic inhibitors and a cell preservative in a liquid medium.
Note: It is normal for the reagent in Cell-Free RNA BCT to have a reddish appearance.
STORAGE AND STABILITY
1. When stored at 18 °C to 30 °C, empty Cell-Free RNA BCT is stable through expiration date.
2. Short-term storage from 2 °C to 40 °C is acceptable for empty Cell-Free RNA BCT for up to 14 days.
3. Do not freeze unfilled Cell-Free RNA BCT. Proper insulation may be required for shipment during extreme temperature conditions.
4. Blood samples collected in Cell-Free RNA BCT are stable for up to 7 days when stored between 18 °C to 25 °。
INSTRUCTIONS FOR USE使用說明
1. Collect specimen by venipuncture according to CLSI GP41-A65.
Prevention of Backflow - Since Cell-Free RNA BCT contains chemical additives, it is important to avoid possible backflow from the tube.
To guard against backflow, observe the following precautions:
a. Keep patient’s arm in the downward position during the collection procedure.
b. Hold the tube with the stopper in the uppermost position so that the tube contents do not touch the stopper or the end of the needle during sample collection.
c. Release tourniquet once blood starts to flow in the tube, or within 2 minutes of application.
2. Follow recommendations for order of draw outlined in CLSI GP41-A65. Cell-Free RNA BCT can be drawn after the EDTA tube and before the fluoride oxalate (glycolytic inhibitor) tube. If a Cell-Free RNA BCT tube immediay follows a heparin tube in the draw order, Streck recommends collecting a non-additive or EDTA tube as a waste tube prior to collection in the Cell-Free RNA BCT.
采血管使用順序
3. Fill tube compley.
4. Remove tube from adapter and immediay mix by gentle inversion 8 to 10 times. Inadequate or delayed mixing may result in incorrect analytical results or poor product performance. One inversion is a complete turn of the wrist, 180 degrees, and back.
5. After collection, transport and store tubes within the recommended temperature range.
Note:
1. For best results, a 21G or 22G needle is advised. Slower fill times may be observed when using a smaller gauge needle.
2. When using a winged (butterfly) collection set for venipuncture and the Streck Cell-Free RNA BCT is the first tube drawn, a non-additive or EDTA discard tube should be partially drawn first in order to eliminate air or “dead space” from the tubing.
