一種新型測(cè)試設(shè)計(jì)用于法醫(yī)市場(chǎng)進(jìn)行鑒別個(gè)人基因組成的比例。

這種測(cè)試叫做DNAWitness，是根據(jù)DNAPrint基因組公司(Sarasota, FL, USA)開發(fā)的技術(shù)為基礎(chǔ)的，該公司聲稱這種檢測(cè)是唯一具有預(yù)測(cè)功能的方法。DNAWitness法醫(yī)技術(shù)分析在犯罪現(xiàn)場(chǎng)發(fā)現(xiàn)的DNA，并在四個(gè)可能的法醫(yī)組織中提供生物地理組成的比例：撒哈拉沙漠以南的非洲、美洲本土、東亞、印歐大陸，從而縮小調(diào)查人員正在追蹤與犯罪有聯(lián)系的潛在疑犯名單。

試劑盒包括所有世界范圍內(nèi)法醫(yī)實(shí)驗(yàn)室進(jìn)行自己家系分析所需的試劑和方案。DNAPrint公司提供的保護(hù)的在線軟件被用于允許調(diào)查人員解釋他們的結(jié)果，將可能的疑犯DNA樣本人體測(cè)量（身體的）特征與DNAPrint公司的家系數(shù)據(jù)庫(kù)進(jìn)行比較。這個(gè)試劑盒能夠在法醫(yī)實(shí)驗(yàn)室和大學(xué)實(shí)驗(yàn)室中常見的毛細(xì)管電泳設(shè)備上使用。

DNAPrint公司法醫(yī)學(xué)技術(shù)協(xié)調(diào)員Zach Gaskin說：“這個(gè)試劑盒將DNAPrint公司強(qiáng)大的法醫(yī)學(xué)檢測(cè)能力直接放到了當(dāng)?shù)胤缸铿F(xiàn)場(chǎng)調(diào)查人員的手中。同時(shí)這還是研究人員有價(jià)值的可以節(jié)約時(shí)間節(jié)約成本的工具，因?yàn)樗鼫p少了調(diào)查人員通常在追蹤過程中所犯的錯(cuò)誤。”

Testing Kit for Forensic Market
 
A new test designed for the forensic market can identify the percentage of an individual’s genetic makeup.

Called DNAWitness, the test is based on proprietary technology developed by DNAPrint Genomics, Inc. (Sarasota, FL, USA), which states it is the only testing method available with this predictive capability. DNAWitness forensic technology analyzes DNA recovered at a crime scene and provides the percentage of bio-geographical (BGA) makeup among four possible genetic groups: Sub-Saharan Africa, Native-American, East Asian, and Indo-European, thereby narrowing the list of potential suspects that investigators are seeking in connection with a crime.

The kit contains all of the reagents and protocols required for forensic laboratories around the world to perform their own ancestry analysis. Proprietary online software provided by DNAPrint is expected to enable investigators to interpret their results and relate them to the likely anthropometric (physical) features of a would-be suspect by referencing DNA samples to DNAPrint’s ancestry databases. The kit can be utilized on capillary eletrophoresis (CE) instruments commonly found in forensic and university laboratories.

“This kit puts the power of DNAPrnt’s forensic technology directly into the hands of local crime-scene investigators,” stated Zach Gaskin, technical coordinator of forensics at DNAPrint. “It is also a valuable time- and cost-saving investigative tool because it reduces the number of false leads that detectives normally would have to chase.”
