Reconstitute in 100 µL of sterile water. Centrifuge to remove any insoluble material. After reconstitution keep aliquots at -20 °C for a higher stability, and at 4 °C with an appropriate antibacterial agent. Glycerol (1:1) may be added for an additional stability. Avoid repetitive freeze/thaw cycles.
Connexin 40 (Cx40), belongs to the connexin family of gap junction proteins, which are expressed in pancreas, kidney, skeletal muscle, liver, placenta and heart. Connexin 40 is highly expressed in vascular endothelial cells, and the mammalian heart (specifically in the atrial myocardium, and the His-Purkinje conduction system). At least three other connexins are expressed in the heart, including Cx37 (endocardium), Cx43 (atrial and ventricular myocardium, and distal parts of the conduction system) and Cx45 (throughout the heart). Cx40 and Cx43 frequently co-localize in cells of the cardiovascular system and participate in the formation of heterotypic gap junction channels.
