![Immunohistochemistry: Lubricin/PRG4 Antibody [NBP1-19048] - Sections of the tibial articular cartilage of 12-week-old normal Mig-6-flox (C) and Mig-6-flox; Prx1Cre conditional knockout (Mig-6-cko) knees (D) immunostained with antibodies against superficial zone protein (SZP, C, D). In normal articular cartilage, immunostaining is localized to cells mainly in the superficial zone (arrows in C) while in Mig-6-cko articular cartilage, immunostaining is dramatically increased and positive cells are located not only in the superficial zone but also in deeper zones (arrows in D). Scale Bar = 50 um.

![Immunohistochemistry: Lubricin/PRG4 Antibody [NBP1-19048] - Sections of six-week old tibial articular cartilage of normal Mig-6-flox (M) and Mig-6-cko (N) joints immunostained with antibodies against superficial zone protein (SZP, M, N). Enhanced marker expression by cells in the superficial and middle zones is evident in the six-week-old Mig-6-cko articular cartilage compared to control Mig-6-flox articular cartilage (arrows). Scale bar = 100 nm.
