🔍 Unlocking the Power of Forensic DNA Analysis with STRs 🔍 Short Tandem Repeats (STRs) are the backbone of forensic DNA analysis, providing unmatched precision in criminal investigations. Here's why they are indispensable: 1. Unique Genetic Markers: STRs are highly polymorphic, making each individual's DNA profile unique. 2. High Discriminatory Power: Utilizing multiple STR loci drastically reduces the chance of a coincidental match. 3. Amplification Efficiency: Even trace or degraded samples can be amplified through PCR. 4. Standardization: Panels like CODIS ensure consistency and compatibility across forensic labs. 5. Statistical Rigor: Statistical analysis supports the reliability of matches in court. 6. Stability: STRs' non-coding nature ensures they remain stable genetic markers over generations. STRs are essential for generating highly discriminative DNA profiles, aiding in the swift and accurate identification of individuals, and bolstering the justice system. #ForensicScience #DNAAnalysis #CriminalInvestigation #Biotechnology

#DidYouKnow the continuous progress of forensic investigation technologies requires the development of less invasive procedures for collecting, screening and sampling small volumes of biological samples? Dried Blood Spot (#DBS) technology has become the preferred method for DNA sample collection for human genetics and forensic DNA identification. The reduced size of DBS allows easy storage of biological samples at ambient temperature, a key factor for forensic laboratories, which typically handle a significant number of samples simultaneously.   📍🌎 Join us at the upcoming Annual Conference of the American Academy of Forensic Sciences, Denver, CO, February 19-24, #Booth103, to learn more about our innovative range of specimen collection cards!   These products find key applications in the forensics field, allowing simple methods for biosample collection, on and off the crime scene, convenient ambient-temperature transportation and storage in laboratories and reliable results.   #forensics #AAFS #WePurifyandProtect #healthandsafety #medical #healthcareindustry #healthcareprofessionals #healthcareinnovation #science #innovation

In a recent email entitled “65% of 5 person DNA profiles incorrect”, Helen Roebuck (Roebuck Forensics) states:  “This substantial 2018 scientific study tested 31 labs worldwide and found that 64% of 5 contributor DNA profiles, and 24% of 4 contributor profiles were incorrectly assigned.” and: “The study also found that 100% of 6 contributor profiles were incorrect.” and: “The DNA likelihood ratio is critically reliant upon the correct assignment of contributors. An “interpretable” profile may become “uninterpretable” with correction to the number of contributors. Correction in the number of contributors may lead to exclusion. 5 or more contributor DNA profiles are “uninterpretable” to all Australian labs, except South Australia. We currently see systemic under assignment of contributors, given that 5 or more profiles are widely uninterpretable.” We are coauthors of this paper [1]. Roebuck’s comments are a misrepresentation of the study although we can see that the relevant figure within the paper could be misunderstood. We have made this information publicly available previously (see link below) and it is a disappointment that Ms Roebuck has not connected with this. https://lnkd.in/gFqdKd2i The situation regarding the Number of contributors (NoC) is not as represented by Ms Roebuck. Underrepresentation leads to false exclusions not false inclusions. This behaviour is well known and not affected by the figure in the paper that Ms Roebuck alludes to. Additionally, you cannot “correct” the NoC in casework since the true NoC (tNoC) cannot be known. If the validation is undertaken on apparent NoC then tNoC is irrelevant.
