• Part 2: Solving Mysteries with Trypsin and Proteinase K 2018-11-05 17:17:39 In Part 1, we discussed using trypsin on bone specimens as a cleaning alternative to sanding in preparation for DNA extraction. In this second part of the series, we cover the details of attaining a higher yield of DNA using proteinase K. Proteinase K for Higher DNA Yield from Bone Specimens DN Proteinase K
  • Part 1: Solving Mysteries with Trypsin and Proteinase K 2018-11-04 23:10:39 Identifying Human Remains Human remains are fascinating. They have many properties that can be used to identify a person: distinct scars, special features, dental x-rays, fingerprint comparisons, or physical facial characteristics. Forensic scientists attempt to identify human skeletal remains in si
  • Attaining High DNA Yield from Sperm Cells using Proteinase K 2018-02-27 12:42:07 There are many techniques that can be used to isolate high quality and high molecular weight DNA from mammalian somatic cells. However, these techniques are ineffective for mammalian sperm. Unlike somatic cells, nearly all histones in sperm cells are replaced by protamines held together by disulfide proteinase k
