Application DetailsImmunohistochemistry (IHC) and Western Blotting (WB). A concentration of 0.1-0.5 µg/mL is recommended for WB. The predicted length of human Connexin-43 is 382 residues and MW of 43 kDa. A concentration of 0.5-1.0 µg/mL is recommended to detect Connexin-43 in formalin fixed and paraffin embedded tissues. Heat mediated antigen retrieval is required. Biosensis recommends optimal dilutions/concentrations should be determined by the end user.
SpecificityHuman Cxn 43, no cross reactivity to other family members is expected
Target Host SpeciesHuman
Species ReactivityHuman, Mouse, Rat
Immunogen DescriptionA synthetic peptide corresponding to the amino acids 366-382 from the C-terminus of human Connexin-43.
Purity DescriptionAffinity purified on antigen column
Reconstitution InstructionsSpin vial briefly before opening. Reconstitute in 100 µL sterile-filtered, ultrapure water to achieve an antibody concentration of 1 mg/mL. Centrifuge to remove any insoluble material.
Storage InstructionsAfter reconstitution, aliquot and store at -20°C for a higher stability. Avoid freeze-thaw cycles.
Batch NumberPlease see item label.
Expiration Date12 months after date of receipt (unopened vial).

Scientific BackgroundA 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 neighbouring 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-43, also known as Gap junction alpha-1 (GJA1), belongs to the class II (alpha) group of connexins and is expressed in the heart and foetal cochlea.
