Further analyses about collagen present in ductal infiltrating carcinoma of human mammary gland indicate that a large amount of it is represented by type I omotrimer that has been separated from the two other present species, type I eterotrimer and type III, by means of fractionated saline precipitation. Quantitative determinations of the three types, extracted by mild pepsin digestion, are also reported.
对人类乳腺导管浸润癌中存在的胶原蛋白的进一步分析表明，其中大量的胶原蛋白以I型同源三聚体的形式存在，该三聚体已通过分级盐沉淀法与另外两种存在的类型，即I型异源三聚体和III型胶原蛋白分离。还报告了通过温和的胃蛋白酶消化提取的这三种类型的定量测定结果。
