PATENT CLAIMS Method of purifying CFTR protein having complex-type glyco
sylation from a mammalian cell
- Providing mammalian cell membrane fraction with which
said complex-type glycosylated CFTR is an integral mem
brane protein
- Alkali-stripping > 60% of peripherally bound membrane
protein from fraction
- Contact. stripped fraction with buffered soln contg alpha lyso
phosphatidylcholine detergent to solubilize > 80% of CFTR
from membrane fractions without solubilizing > 50% of non-
CFTR protein
- Contact. solubilized CFTR with anti-CFTR MAb in presence
of concn of alpha lysophosphatidylcholine detergent that
permits specific interaction of CFTR to Ab
- Dissociating Ab-CFTR complex in presence of cholate de
tergent
