The methods can be used to detect a single starting nucleic acid target molecule.

Abstract: A coating formulation for making a porous coating on a laboratory apparatus is provided. The formulation comprises 100 parts by weight hardenable resinous material, and from about 0.1 to about 50 parts by weight blowing agent based on the 100 parts by weight resinous material. The resinous material has a hardening time which is sufficiently short such that gas generated by the blowing agent is entrapped within the resinous material. The coating formulation is hardenable upon application to a surface of a laboratory apparatus to form a porous coating which is used for marking purposes or for the retention of biological samples. Methods of retaining a biological sample on a coated laboratory apparatus having a surface made of the coating formulation are also provided.

Abstract: A microbiological assembly is provided having a resealable seal between a support and a cover. The support has a surface which includes a patterned layer and defines at least one sample retention well. The cover has a surface which contacts a sealant and the sealant is disposed on at least one of the support and the cover. The sealant is adapted to releasably bond and resealably seal the cover to the support. The sealed assembly minimizes contamination and drying of liquid sample retained by the sample retention well. A method of examining a biological culture is also provided and includes the steps of retaining a biological sample within the sample retention well of the assembly, sealing the cover to the support with the sealant between the sealing surface and the support surface, physically separating the cover from the support surface, and then either resealing the cover or sealing a second cover to the support using the same sealant.
