It seems very odd to me that although the price of the Promega protein G magnetic beads is the same as the competitors their capacity is a least 40 times higher. Have you used it and can help me out?

I was wondering if you went with the promega magne bead option and if you did how you found them as was also thinking of using them due to their high stated binding capacity
