I looked up some papers and found MANY Materials and Methods sections describing antibodies that have been discontinued or that were made by a company that doesn't exist anymore (even when restricting my search to the last two years or so), but found nothing currently useful. I wrote to the tech support people at the company that acquired one of the now-defunct companies and they recommended one of their products (AbD Serotec AHP1292), but I can't find any papers that have used it. Also contacted the PI of a lab that gave us the idea to find this antibody originally (his protocol refers to one that no longer exists) and haven't heard back.
Help?
