Abstract: The present disclosure describes the identification and use of aptamers and photoaptamers having slower dissociation rate constants than those obtained using previously described methods. Specifically, the present disclosure describes methods for the identification and use of aptamers to one or more targets within a histological or cytological sample, which have slow rates of dissociation. The aptamers may be used to assess localization, relative density, and presence or absence of one or more targets in cytological and histological samples. Targets may be selected that are specific and diagnostic of a given disease state for which the sample was collected. The aptamers may also be used to introduce target specific signal moieties. In addition to target identification, the aptamers may be used to amplify signal generation through a variety of methods.

Abstract: Embodiments provide a slide assembly device having a static tooling base which is statically and solidly affixed to a base such as a table and a moveable tooling arm that is rotatable about a hinge connected to the static tooling base, so that moveable tooling arm rotates about the hinge in a manner similar to a book cover opening and closing. The embodiments further provide an upper slide chuck that is removably attachable to the moveable tooling arm and a lower slide receiver that is removably attachable to the static tooling base. The upper slide chuck is configured to hold an experimental slide via a vacuum mechanism to engagedly hold the experimental slide to the upper slide chuck while the moveable tooling arm is rotated about the hinge from an open-book position to a closed-book position.

Abstract: The present invention provides aptamers that specifically bind to the EGF receptor in a sample, and diagnostic and analytical methods using those aptamers. In some embodiments, the aptamers include a 3? cap. In some embodiments, the 3? cap is an inverted deoxythymidine. In some embodiments the aptamers include a spacer and at least one moiety selected from the group consisting of binding pair member and a detectable label, wherein the spacer is attached to the 5?-end of the aptamer and the moiety is attached the 5? end of the spacer. In some embodiments the spacer is hexaethylene glycol. In some embodiments, the binding pair member biotin. In some embodiments the detectable label is a fluorophore.
