The antibody specifically recognizes and reacts with a common determinant of the CD44 class of glycoproteins. This antibody has been reported to block the interaction between hyaluronan and CD44 (see application references). Variables associated with assay conditions will dictate the proper working dilution.

Advanced tissue engineered heart valves must be constructed from multiple materials to better mimic the heterogeneity found in the native valve. The trilayered structure of aortic valves provides the ability to open and close consistently over a full human lifetime

The differentiation of osteoclasts, cells specialized for bone resorption, is governed by two key factors, macrophage colony stimulating factor (M-CSF) and receptor activator of nuclear factor kappaB ligand (RANKL). The extracellular matrix (ECM) is an important factor influencing cell fate.

HA activates CD44 to stimulate RANKL expression in bone marrow stromal cells. HA stimulation of RANKL is blocked by anti-CD44 antibody and is absent in cells from CD44(-/-) mice. CD44(-/-) mice exhibit thicker cortical bone and a smaller medullary cavity

Hyaluronan is enriched in many types of human cancers, and manipulations of hyaluronan expression or interactions have a major influence on tumor progression in animal models. Increased ErbB2 activity is characteristic of several cancers and is responsible for many aspects

Chronic neurodegeneration and acute injuries lead to neuron losses via diverse processes. We compared retinal ganglion cell (RGC) responses between chronic glaucomatous conditions and the acute injury model. Among major RGC subclasses, αRGCs and intrinsically photosensitive RGCs (ipRGCs) preferentially survive
