I need to have a very high dillution of it 1/3k-1/5k and a very low background on my homemade ELISA. Best I have is 1/1000 but cost a lot because I do a lot. Any suggestion?

ty but not always availlable before you buy and do it yourself.
How do I find out if a Journal I want to publish with is indexed in Scopus, Scimago or Thompson Reuters?
