Fig. 4. SDSPAGE of the acetylcholine receptor purified from the numb fish
N. tasmaniensis on the TDAC affinity column. Fractions 3, 5 and 7,
correlating to the peak absorbance in Fig.
3A, were run on a 412% Bis-Tris NuPAGE gel and stained with
Coomassie. The protein bands corresponding to the four subunits comprising the
acetylcholine receptor are indicated on the right. The protein running between
the
and ß subunits is mostly likely the
subunit, which is
known to run as a doublet.
