Is everyone using the complement control cells:

TRM.40210 DAT Phase II

When performing an antiglobulin test with anti-C3 antiglobulin reagents, C3-coated red blood

cells are used as a control in all negative antiglobulin tests.

and where are you getting them from? I'm not happy with my current vendor (they don't come on a predictable standing order) and I just saw that Hemobioscience has them. Any experience with that vendor?

Thanks!

I use Immucor's product - significantly less expensive than HemoBioscience (due to purchasing programs). I receive them regularly with no problem. Using them in tube is arduous in that you really have to try to get a decent 1+ reaction. I use them in buffered gel with anti-C3b,-C3d - they are always 3-4+. I have heard that Quotient is working on a kit to allow you to make your own Complement + check cells.

We use Immucor and have not had any problems with our standing order. It does help if you let the check cells sit a few minutes before you read them. They tend to be stronger.

We switched to Bioscience from Immucore because of price

We do the same as David. Beautiful reactions in gel.

We use the Immucor cells. No shipping problems and we always see nice reactions in tube. (We do have a contract that gives us good pricing.)
