Concerning the half life of the GUS protein in plant cells, Jefferson et al.,
reported it to be approximately 50 hours in living mesophyll protoplasts

Jefferson, R.A., Kavanagh, T.A. and Bevan, M.W. (1987). GUS fusions:
B-glucuronidase as a sensitive and versatile gene fusion marker in higher
plants. EMBO J. (6). pp3901-3907.

Hope this helps,
