1. An apparatus for growing protein crystals comprising:
- (a) a plurality of equilibrating solution reservoirs each having a bottom wall and an inclosing side wall so fixed in said apparatus as to terminate in a top disposed in a first plane;
(b) a drop supporting means for supporting a protein drop disposed within each of said equilibrating solution reservoirs, each said drop supporting means comprising an upstanding column spaced apart from said side wall and having a protein solution depression disposed on the top thereof, the top of said protein solution depression being located below and parallel said first plane; and
(c) cover means for engagement with said top of said equilibrating solution reservoirs for sealing said reservoirs wherein each of said protein solution depressions is in communication only with said equilibrating reservoir within which it is disposed.

Abstract
An apparatus for growing diffraction quality, protein crystals by vapor diffusion techniques. The apparatus includes a plurality of equilibrating solution reservoirs each having a side wall terminating in a top wall disposed in a first plane; a column disposed within each of the equilibrating solution reservoirs, each column having a protein solution receptacle including a side wall terminating in a top wall disposed in a second plane spaced from the first plane; and a cover having a non-greasy adhesive on one surface therof for sealable engagement with the top walls of the equilibrating solution reservoirs for sealing the reservoirs relative to atmosphere.

7. An apparatus for growing protein crystals, comprising:
-
(a) interconnected side and end walls defining an enclosure, said walls terminating in a top edge disposed within a first plane; (b) a plurality of equilibrating solution reservoirs formed interiorly of said enclosure;
each said reservoir including a bottom wall and an upstanding inclosing side wall terminating in an edge disposed within said first plane;(c) an upstanding column disposed within each of said equilibrating solution reservoirs, each said column having a generally cup shaped protein solution carrying receptacle having a wall terminating in an edge disposed in a second plane, said second plane being spaced below said first plane and parallel to said first plane; and
,(d) a sealable cover for engagement with said edges of said side and end walls and for engagement with said edges of each of said reservoirs wherein each said protein solution carrying receptacle is in communication only with said equilibrating reservoir within which it is disposed. - View Dependent Claims (8, 9, 10, 11, 12)
