Description

PA1-28870 has been successfully used in ELISA, immunohistochemistry (frozen tissue), immunoprecipitation, and Western blot applications. NOTE: The preparation of a specific antibody to Collagen III's uninterrupted "Glycine-X-Y" triplet repeat requires a non-denatured epitope format. Consequently, it is recommended to use this antibody in a Western blot using non-denaturing or "native" conditions. Store as concentrated solution. Centrifuge briefly prior to opening vial.

10.1371/journal.pone.0214072.g005 Fig 5 Changes in superficial layer collagens during early stage TMJ OA. Immunolabeling of fibrillar collagens in the TMJ illustrating changes in the composition of the superficial layer extracellular matrix that accompanies the progression of early stage TMJ-OA. Collagen I (A-C) is immunolabeled using a brown chromogen. Collagen II (D-F) and Collagen III (G-I) are immunolabeled using a pink chromogen. Cell nuclei are labeled in purple with hematoxylin. Tissues from non-surgical controls (A, D, G) are compared with 4 (B, E, H) and 8 (C, F, I) week post-injury tissues. All images are representative of their experimental group (n = 3) and taken from homologous regions of the mandibular condyle. Differences in the shape of the condylar reflect variable amounts of condylar flattening, typical of the surgical model. Medial is to the right in all joints. Scale bars equal 50 mum. Note strong staining for Collagens I/III in the superficial layer in post-injury tissues, with Collagen II restricted to the deeper chondroblastic/hypertrophic layers. Primary and secondary antibody controls were negative.
