title: Keratan sulfate proteoglycan isolated from the estrogen-induced medullary bone in Japanese quail.
abstract: 1. Two proteoglycans isolated from the femurs of quail actively producing medullary bone were separated using DEAE Bio-Gel A. 2. The first to elute in the gradient was a keratan sulfate proteoglycan with an average buoyant density of 1.53 g/ml and a Kav = 0.57 on Sepharose CL-4B. 3. The second proteoglycan to elute contained chondroitin 4-sulfate. 4. Apparently only the keratan sulfate proteoglycan is associated with the new medullary bone matrix.
