I am curious if anyone knows of a cell line that endogenously expresses Cx26 or Cx32. I would prefer a line that only expresses these connexins and does not express Cx43.
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.
