BioTX’s patent pending TED evidence collection system is designed to support a variety of evidence collection requirements from Touch DNA to dried blood, liquids, powders, and fibers.  The TED system incorporates a hand held vacuum device with different end attachments specifically designed for the appropriate evidence to be collected.  The evidence is collected in vials ready for lab processing to minimize manual handling.  Touch DNA samples are captured from different surfaces using a Nylon tip attachment. The evidence surface is wetted with buffer.  Cells are collected on the surface of the Nylon tip, while solubilized DNA is collected inside the tip.  When the sample has been collected the tip is replaced into the provided DataMatrix labeled vial. Once the tip and vial are received at the lab they are processed using standard laboratory procedures. The tip requires no cutting and is inert to all extraction buffers.

該系統(tǒng)旨在支持從Touch DNA到干血，液體，粉末和纖維的各種證據(jù)收集要求。TED系統(tǒng)集成了一個(gè)手持式真空設(shè)備，該設(shè)備帶有專門設(shè)計(jì)用于收集適當(dāng)證據(jù)的不同末端附件。證據(jù)收集在小瓶中，準(zhǔn)備用于實(shí)驗(yàn)室處理，以最大程度地減少人工操作。使用尼龍尖端附件從不同的表面捕獲觸摸式DNA樣品。證據(jù)表面被緩沖液弄濕。細(xì)胞被收集在尼龍尖端的表面，而溶解的DNA則被收集在尖端內(nèi)部。收集樣品后，將尖端替換為提供的帶標(biāo)簽的DataMatrix小瓶。在實(shí)驗(yàn)室收到吸頭和小瓶后，將使用標(biāo)準(zhǔn)實(shí)驗(yàn)室程序?qū)ζ溥M(jìn)行處理。尖端無需切割，并且對(duì)所有提取緩沖液均呈惰性。
