10. A lid assembly according to claim 1, further comprising:
a stop flange extending circumferentially around and protruding radially outward from the closure section, the perimeter of the closure section defining a circle; and
a catch flange extending along at least one edge of the cover section and protruding radially outward therefrom, the catch flange and stop flange configured and positioned to overlie one another and retain the cover section attached to the closure section in both the open and closed positions.
11. A lid assembly according to claim 10, wherein the cover section is mounted on top of the closure section and the stop flange is positioned directly above the catch flange.
12. A lid assembly according to claim 11, wherein the cover section can drop down and register with part of the closure section in the closed position with a gap between the stop flange and the catch flange.
13. A lid assembly according to claim 11, wherein the cover section can drop down and register with part of the closure section in the open position with a gap between the stop flange and the catch flange.
14. A lid assembly according to claim 11, further comprising a gap between the stop flange and the catch flange in the open and closed positions, whereby the cover section, while being rotated about the hub between the open and closed positions, can rise until the catch flange contacts the stop flange.
15. A lid assembly according to claim 1, wherein the hub defines a generally vertical axis about which the cover section can rotate between the closed and open positions.
16. A lid assembly according to claim 1, further comprising:
a bumped up region protruding upward on the closure section; and
a corresponding depression formed upward on an underside of the cover section, wherein the bumped up region registers and nests with the corresponding depression with the cover section in the open position.
17. A lid assembly according to claim 16, further comprising a ramped surface between the bumped up region on the closure section and the access opening.
18. A lid assembly according to claim 17, wherein an edge of the cover section lies at a base of the ramped surface in the closed position.
19. A lid assembly according to claim 1, wherein the cover section and the access opening each have a generally semi-circular shape.
20. A storage container comprising:
a base with a bottom, a side wall, an interior storage space, and an open top end; and
a lid assembly removably attached to the open top end of the base, the lid assembly having
a closure section positioned over the open top end and having a top panel, an access opening through the top panel, and a lid skirt coupled to the base and extending around the closure section;
a hub;
a cover section mounted on the closure section and rotatable about the hub between a closed position covering the access opening and an open position exposing the access opening;
an annular stop flange protruding outward from and extending around the perimeter of the lid skirt; and
an annular catch flange protruding outward from an outer edge of the cover section,
wherein the catch flange is spaced directly below the stop flange in the open and closed positions to retain the cover section connected to the closure section.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.

12: A method for identifying an agonist of polypeptide, which comprises:
(a) contacting a cell expressing the polypeptide with a candidate compound; and
(b) determining whether or not the candidate compound induces the generation of a signal that can be used as an indicator for the activation of the polypeptide, wherein the polypeptide is expressed by one of the following polynucleotides
(a) a polynucleotide which encodes a polypeptide comprising the amino acid sequence of SEQ ID NO: 2 or 20;
(b) a polynucleotide which comprises a coding region of the nucleotide sequence of SEQ ID NO: 1 or 19;
(c) a polynucleotide which encodes a polypeptide comprising the amino acid sequence of SEQ ID NO: 2 or 20 wherein one or more amino acids are substituted, deleted, added, andor inserted; and
(d) a polynucleotide which hybridizes to a DNA comprising the nucleotide sequence of SEQ ID NO: 1 or 19 under a stringent condition.
13: A method for identifying an antagonist of a polypeptide, which comprises:
