Cadherins are a family of transmembrane glycoproteins involved in Ca2+-dependent cell to cell interactions. The members of the family are differentially expressed in various tissues and function in the maintenance of tissue integrity, morphogenesis, and migration. Cadherins are divided into type I and type II subgroups. Type I cadherins include epithelial cadherin (E-cadherin), neural cadherin (N-cadherin), placental cadherin (P-cadherin) and retinal cadherin (R-cadherin). Type II include kidney cadherin (K-cadherin) and osteoblast cadherin (OB-cadherin). One of the best characterized cadherins is E-cadherin (epithelial cadherin or cadherin-1). It consists of calcium binding extracellular domains responsible for interactions with other E-cadherin molecules on neighboring cells and interaction with integrin alphaEbeta7. The cytoplasmic domain of E-cadherin is linked to the actin cytoskeleton through cytoplasmic catenin proteins, thus establishing a complex localized to adherens junctions. In carcinomas E-cadherin is frequently downregulated, which is consistent with its function of an invasion suppressor in normal epithelia.

Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
