ABfinity™ recombinant antibodies are rabbit monoclonal antibodies, unmatched for producing superior results. ABfinity™ antibodies are developed by immunizing animals, screening for functionality, cloning the immunogen-specific antibody genes into high-level mammalian expression vectors, produced on a large scale and purified with Protein A.
ABfinity™ oligoclonal antibodies comprise a selection of multiple different recombinant monoclonal antibodies, providing the best of both worlds—the sensitivity of a polyclonal antibody with the specificity of a monoclonal, all delivered with the consistency only found in a recombinant antibody. While functionally the same as a polyclonal antibody—recognizing multiple epitope sites on the target and producing higher detection sensitivity for low abundance targets when compared with monoclonal antibodies—an oligoclonal antibody has a known mixture of light and heavy chains. This exact population can be produced in every lot, circumventing the biological variability typically associated with polyclonal antibody production.
Intact IgG appears on a non-reducing gel as ~150 kDa band and upon reduction generating a ~25 kDa light chain band and a ~50 kDa heavy chain.
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.
