NEW - Estimation of Transgene Copy Number – Predicting Expression Level

This pioneering technology allows investigators to predict expression levels of transgenes in young founder animals and prior to actual expression and/or phenotyping. Projected non-expressing founders can then be culled prior to breeding, substantially reducing breeding costs and work load.

Can You Believe? Even Ripley’s Believe It or Not®!?

Therion was contacted by Ripley’s Believe It or Not® to conduct DNA testing on a two-trunked elephant that was discovered. Through Therion’s DNA analysis it was determined that the two trunks contained identical DNA patterns and that the trunks were indeed from the same animal and had not been grafted on.

BELIEVE IT OR NOT: Ripley's expanding empire of the bizarre
The first thing you'll probably notice is the shark. At 17 feet long, it's the biggest ever caught on rod and reel. What's left of its two terrifying tons now hangs preserved above a dull warehouse floor.

Wildlife Forensics

Therion International recently worked with the Pennsylvania State Police in a murder investigation. In 1999, at the request of the Pennsylvania State Police, Therion conducted DNA testing to identify numerous deer tissues, bloodstains and meat samples found around the crime scene and in the suspects home. Entrails from the field and crime scene area, as well as blood samples on the victim were positively matched with those samples found at the suspect’s home. These DNA results and other evidence led to the murder conviction of the suspect on December 9, 2005. Articles are linked below:

Suspect arrested in death of hunter
In 1997, state troopers investigating the shooting death of a hunter in the woods of Fayette County seized animal blood, meat, tissue and "gut piles" at the scene as evidence. Four months later, search warrant in hand, they went to the Uniontown home of a suspect and confiscated deer steak and chops from his freezer. Recently, a DNA analysis confirmed a match between the deer meat at the scene and in Lawrence Cseripko's freezer.
