Hi Yall, For perhaps the first time ever, the internet has failed me: I cannot seem to find a definition of "immunoreactive ceruloplasmin" anywhere. Possibly we don't actually know what it is for? This is the article in which I first saw it mentioned. I find elsewhere that it may not contain copper. Is it the same as apoceruloplasmin? Does it have a physiological role that we know of? I rarely ask for help like this, but after three pages of google searches with no definition I think it is time to see if any of the smart people over here already know! Thank you.
