The unique DNA IQ™ Resin eliminates PCR inhibitors and contaminants frequently encountered in casework (e.g. denim, leather and soil). Even bloodstains as small as 0.1µl can be processed and the DNA amplified to give a complete STR profile. To extract stains, just heat your sample in Lysis Buffer for 30 minutes and centrifuge. DNA IQ™ Resin then is added, and samples are washed using a magnetic stand. Thirty minutes later, you have purified DNA.
Some samples, such as tissue and hair, require pretreatment with Proteinase K. In addition, extracting DNA can be difficult from substrates such as denim, envelopes, carpet, etc.
The Tissue and Hair Extraction Kit increases DNA yield from challenging casework samples and substrates. The kit uses Proteinase K and other reagents to remove proteins and other components from the DNA, helping to ensure maximal yield and recovery of DNA from casework samples. The DNA then can be purified using the DNA IQ™ System.
