Studies from University of California Have Provided New Data on Bone Research (Ultrafiltration for asphalt removal from bone collagen for radiocarbon dating and isotopic analysis of Pleistocene fauna at the tar pits of Rancho La Brea, Los ...)

By a News Reporter-Staff News Editor at Science Letter -- Data detailed on Bone Research have been presented. According to news reporting out of Los Angeles, California, by NewsRx editors, research stated, "A novel protocol to purify bone collagen for radiocarbon dating and stable isotope ratio analysis from asphalt-impregnated skeletal remains stored in the George C. Page Museum of La Brea Discoveries (Los Angeles, California) is presented. This simple technique requires that bones be crushed (1-2 mm), sonicated in a 2:1 toluene/methanol solution, and gelatinized at 75 C overnight to break down collagen strands for ultrafiltration."

Our news journalists obtained a quote from the research from the University of California, "However, here the traditional protocol of ultrafiltration is reversed, and the high molecular weight fraction (>30 kDa) contains mainly the asphalt (too big to pass through the filter), while the lower molecular weight fraction (3 kDa) is then performed on the Rancho La Brea site are presented. Finally, while this protocol was specifically designed to extract collagen from samples at the Rancho La Brea site, it is likely that it can be applied to other localities (e.g."

According to the news editors, the research concluded: "Cuba, Ecuador, Peru, Venezuela, etc.) where bones have been impregnated with petroleum."
