    • Degradation of Beta-Actin in aging blood and semen stains 

      Beaton, Elizabeth; Allen, Robert; Fu, Jun (Oklahoma State University Center for Health Sciences, 2022-02-18)
      Piecing together a crime scene is one of the most significant components of any forensic investigation and estimating the age of biological stains at a scene can be crucial to the case. Several studies have demonstrated a ...

    • Detection of RNA methylation patterns of forensically relevant transcripts in dried bloodstains 

      Lohr, Chaelynne; Fu, Jun; Allen, Robert (Oklahoma State University Center for Health Sciences, 2022-02-18)
      RNA degradation kinetics can be used to estimate the age of a biological sample found at a crime scene. RNA sequencing of transcripts from various tissue types shows that degradation occurs faster at the 5’ end than the ...

    • Single nucleotide polymorphisms in touch DNA 

      Riet-Kerk, Gentry; Allen, Robert; Pritchard, Jane (Oklahoma State University Center for Health Services, 2020-02-28)
      It is widely known that DNA can be recovered from body fluids such as blood, semen, and saliva. All of which are commonly encountered at crime scenes. In fact, it is often this type of evidence that leads to the perpetrator ...

    • Study of time dependent degradation of mRNA encoding the SPRR3 and S100A9 gene markers in saliva stains 

      Woodson, Kayla; Fu, Jun; Allen, Robert (Oklahoma State University Center for Health Sciences, 2022-02-18)
      When a body fluid stain is found at a crime scene, it may be beneficial to use the RNA found within to approximate the age of the stain. This is important in cases where a person of interest has been known to be in a ...
