title: Protein and lysozyme content of adult human nucleus pulposus.
abstract: A radiologically normal human nucleus pulposus was extracted with 4 M guanidinium chloride and the non-collagenous proteins separated from the proteoglycans by dissociative density gradient centrifugation. Lysozyme was identified as a matrix constituent of the normal, mature human nucleus pulposus.
