Connexin 31 Antibody (LL8) is a mouse monoclonal IgG1 kappa light chain antibody that detects connexin 31 protein of human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). Anti-connexin 31 antibody (LL8) is available as a non-conjugated format. Connexin 31, also known as GJB3, plays a crucial role in cell communication by forming gap junctions that allow the passage of ions and small molecules between adjacent cells, which is essential for maintaining tissue homeostasis and coordinating cellular responses. Connexin 31 is primarily located in the plasma membrane of various tissues, including skin, testis, placenta, cochlea, and developing hindbrain, and in mice, connexin 31 is also found in peripheral auditory nerves. Proper localization of connexin 31 is vital for function, as disruptions in expression or localization can lead to severe consequences, such as non-syndromic sensorineural deafness autosomal dominant type 2 (DFNA2) and erythrokeratodermia variabilis (EVK). These conditions highlight connexin 31′s importance in auditory and skin health, making connexin 31 a significant target for research in understanding gap junction-related pathologies.

I am using connexin 31 (LL8): sc-81803 for immunofluorescence, what dilution of this antibody should I use?

Asked by: Trav11
Thank you for your question. We recommend a starting dilution of 1:50. However, optimal antibody concentration should be determined by titration. Please find our full immunofluorescence protocol here: https://www.scbt.com/scbt/resources/protocols/immunofluorescence-cell-staining
