Greetings. Welcome to Wikipedia. Thanks for your edit. I made this edit and I think you'd benefit from seeing the WP:Cheatsheet (signatures would go on Talk:G_protein-coupled_receptor but not the article page, for example). Let me know if you have any questions at my talk page or you can ask at the WP:Help desk or WP:Teahouse. Best wishes. Biosthmors (talk) 16:32, 7 February 2013 (UTC)Reply

You're welcome. And how I typically add citations here is by using a PubMed ID number and following the method described at User:Biosthmors/Intro_Neuro#Citations. You might find that helpful. Best. Biosthmors (talk) 17:13, 7 February 2013 (UTC)Reply
