Connexin 26/GJB2 Antibody - BSA Free

Western Blot: Connexin 26/GJB2 Antibody [NBP2-41304] - Western blotting analysis detects Cx26 using R(alpha)Cx26-Ct or R(alpha)Cx26-cl antibodies. (a) R(alpha)Cx26-Ct (A) and R(alpha)Cx26-cl (B) antibodies detected a specific 26kDa band on pig heart tissue lysates (lanes A and B are cropped blots obtained from the same gel). R(alpha)Cx26-cl recognized the 26kDa band on human and rat heart (H) lysates and on rat liver (L) sample (positive control) although two unspecific bands at molecular weights lower than 26kDa were detected. No bands were detected on smooth muscle (SM) tissue lysates (negative control) by R(alpha)Cx26-cl. R(alpha)GAPDH was used as protein loading control for rat tissue samples run on the same gel.

Immunocytochemistry/Immunofluorescence: Connexin 26/GJB2 Antibody [NBP2-41304] - Cx26 distribution at level of the cardiomyocyte cytoplasm. Confocal laser scanning microscopy: representative images of rat and pig heart sections. Double immunofluorescence analysis for Cx26 (red) and Cx43 (green) show a distinct cell localization of the two Cxs. (a) Three dimensional picture of the maximum intensity projection of the raw images of longitudinal rat heart section treated with R(alpha)Cx26-cl and M(alpha)Cx43. Scale bar: 20um.

Representative images of immunohistochemical analysis for Cx26 by R(alpha)Cx26-Ct or R(alpha)Cx26-cl antibodies. Longitudinal (c and d) sections showing positivity in cardiomyocytes and in smooth muscle cells of vessel (arrow); Rat (d) immunoperoxidase shows brown immunoreaction in the cell cytoplasm of working cardiomyocytes and in smooth muscle cells of vessels (arrows); positivity of cardiomyocytes and smooth muscle cells has shown, at higher magnification, in longitudinal (d) and cross sections (c); Negative controls are shown in the squares. Scale bars: 50um. Image collected and cropped by CiteAb from the following publication (nature.com/articles/s41598-018-32405-2), licensed under a CC-BY license.

Background

Connexin-26 / GJB2 is a gap junction consists of a cluster of closely packed pairs of transmembrane channels, the connexins, through which materials of low molecular weight diffuse from one cell to a neighboring cell. Each connexin is composed of a hexamer of connexin proteins. Connexins are a multi-gene family of highly related proteins. At least a dozen distinct connexin genes have been identified and many are expressed in a tissue-specific manner. Two distinct lineages, class I (beta) and class II (alpha), have been identified in mammals. Connexin-26 belongs to the class 1 (beta) group of connexins. Mutations in Connexin-26 are associated with genetically derived hearing impairments, including autosomal recessive non syndromic deafness.
