- Description of Target:
- Gap junctions were first characterized by electron microscopy as regionally specialized structures on plasma membranes of contacting adherent cells. These structures were shown to consist of cell-to-cell channels. Proteins, called connexins, purified from fractions of enriched gap junctions from different tissues differ. The connexins are designated by their molecular mass. Another system of nomenclature divides gap junction proteins into 2 categories, alpha and beta, according to sequence similarities at the nucleotide and amino acid levels. For example, CX43 (MIM 121014) is designated alpha-1 gap junction protein, whereas CX32 (GJB1; MIM 304040) and CX26 are called beta-1 and beta-2 gap junction proteins, respectively. This nomenclature emphasizes that CX32 and CX26 are more homologous to each other than either of them is to CX43.

|How do Aviva’s reagents play a role in your experimental goals?||Before I receiving Aviva, I even did not know the existence of it. Our lab purchased antibodies from different companies. But after I tried this sample from Aviva, I have to say this antibody is very sensitive.|
|How would you rate this antibody on a scale from 1-5 (5=best) nad why?||4|
|Would you use this antibody in future experiment?||Yes, I will.|

|If the antibody works, do you plan to use it in future experiments or to publish your data? Why or why not?||Yes, for part of my experiment, I will use it to verify my mouse Cx26 from purified insect cell. But for other experiment, especially for cell image, I have to find other good antibody which can specifically recognize human Cx26.|
