Are Russian Blue mixes as hypoallergenic as pure breeds?

My husband is a huge cat lover, but I'm allergic! (not severely, but enough to be uncomfortable if living with a cat) I did some research and I found that Russian Blues are hypoallergenic. They look like beautiful cats with a temperament that's perfect for our quiet house, but every pure Russian Blue I've found is so expensive! The cheapest I can find is $900.
I was wondering if anyone knew if a Russian Blue mix would be as hypoallergenic (or close enough) as a pure breed.
Thanks in advance!
I find that I'm not bothered by my in-law's cat when its just been bathed, but I do react more after its licked itself-which makes me think that I'm allergic to the saliva. Well I did some research and it's not the saliva that people are allergic to. It's a protein called fla-d or something. It's found in saliva and when a cat licks itself, the protein dries on the fur and skin and creates dander. I read that this is what most people are allergic to. I read that Russian Blues create very little of this protein, which is what makes them hypoallergenic. But of course, this only applies to people who are allergic only to this particular protein. I plan to spend some time with the cats to see how I react, but I thought that they are pretty much my only possibility-but I didn't want to waste time with mixes if they don't have this quality. So basically that's what I'm wondering.

I have 2 Russian Blue cats, and a friend who is allergic to cats. She finds she reacts more to one but still develops an allergy to both so I really have doubts about them being hypoallergenic. But they do have a very quiet, loving disposition.
