51.   The dried residues were then acetylated as described above and platelet activating factor was assayed.

52.   Monoiodo-glucagon was prepared and purified as described above for PYY.

53.   Supernatants were acidified with trichloroacetic acid and analysed for calcium and phosphate as described above.

54.   At this time the basal and meal stimulated gastrin concentrations were reassessed as described above.

55.   All eluates were assayed with the three assays described above.

56.   Cell surface expression was tested on unfixed cells and was performed according to the method described above.

57.   Having stopped the process, as described above,

58.   If this is successful it may be run as described above.

59.   The module can then be scanned again as described above.
