I am looking for a dominant negative Wiskott Aldrich Syndrome Protein Mutant. I would prefer if it has an mCherry tag. Our lab would pay for shipping and acknowledge your contributions to any future paper that would result from this mutant.
Just a generic question, what is the average half-life of a typical membrane protein? If you have a review off hand that could be sent to me, that would be greatly appreciated.
