Water is very effective in leaching the collagen proteins out of the bone, leaving only bone carbonate.Thus, it’s possible that the bones have very limited collagen.Bones that have been drilled or powdered prior to submission to the laboratory may not lend themselves to a robust pretreatment that can ensure the accuracy of the results.We DO NOT recommend that bones be drilled or powdered prior to sending to our laboratory.Any rootlets present will be removed when replenishing the acid solutions.At this stage, the lab will perform a thorough visual inspection of the collagen quality.

Antlers – Chunks, chips, and shavings are best for radiocarbon dating.However, the material will be listed as “organics” in the final report instead of “bone collagen.” This is due to the requirement by our ISO/IEC 17005 accreditation that if we did not perform the chemical pretreatments and/or extractions, we cannot specifically testify as to the material that was dated because certain steps affecting the sample quality have been outside of our control and scope of our accreditation.Do not place extracted collagen directly into Ziplock bags.VERY IMPORTANT: It is well known that collagen preservation is not homogenous throughout bone fragments.It is possible the small sub-sample taken for the % collagen yield test is not representative of the entire bone.
