It forms the organic component of bone and dentine, makes up approx. 20% of these hard tissues and is mainly present as type I collagen.<\/p>\n\n\n\n<p>Carbon and nitrogen are main elements in collagen and usually well preserved even in archaeological contexts. Collagen is therefore the most frequently investigated material of human skeletal remains with regard to&nbsp;<sup>14<\/sup>C dating and stable nitrogen and carbon isotope analyses for diet reconstruction.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Sample properties<\/h2>\n\n\n\n<p>For&nbsp;<sup>14<\/sup>C dating as well as stable carbon and nitrogen isotope analysis, collagen is extracted from bone or dentine by demineralization with weak hydrochloric acid. This usually requires a sample size of at least 1 g to start with.<\/p>\n\n\n\n<p>Collagen extracted in external laboratories can also be examined after consultation. In this case, minimum sample sizes are 3 mg for&nbsp;<sup>14<\/sup>C dating and 3 &#8211; 5 mg for stable C and N isotope analyses (analysis in triplicates).<\/p>\n","protected":false},"template":"","meta":{"editor_notices":[]},"class_list":["post-616","materials","type-materials","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Collagen - CEZA EN<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/ceza.de\/english\/cezapedia\/materials\/collagen\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Collagen - CEZA EN\" \/>\n<meta property=\"og:description\" content=\"Description Collagen is a structural protein and provides elasticity and torsional capacity of biogenic hard tissue.
