摘要:
A method for obtaining an actual linear standard curve in a sandwich type of immunoassay where a first antibody bound to an insoluble support and a second unbound labelled antibody complex with the antigen contained in a test sample to form an insoluble antibody:antigen:labelled antibody complex which is then detected. Unbound unlabelled first antibody and/or unbound unlabelled second antibody are added to the reaction mixture to divert excess antigen away from the desired end-product complex, thus rendering the antigen of interest the rate-limiting factor in the overall immunoreaction. This results in a pseudo first-order reaction which produces an actual linear standard curve.

A docking device comprises a body, a stand two fixing members and two connecting members wherein the body includes an expansion portion with multiple I/O ports and a connecting portion. With the connecting member crossing through the connecting portion of the body the fixing member and the stand, the body can be rotated relative to the stand, which makes it convenient for a user to insert or pullout the electronic wire—cords cable or lines into or from the docking device.

An image snapping device includes a body, a support rod, an image-snapping module and an outer hollow cylinder. The support rod is pivotally connected to the body. The image-snapping module is pivotally connected to the support rod and has a camera rotatable relative to the support rod. The outer hollow cylinder houses the image snapping module and is rotatably connected with the image snapping module, wherein the outer hollow cylinder has multiple lenses, one of which the camera is selectively aligned with.

A keyboard for storing a remote controller, including a pusher that is slidable within a space underneath the keyboard, an elastomer disposed within the space for pressing against one end of the pusher, a controller shaped to match contours of the space and having a tongue provided thereon, and a hook disposed within the space for detachably connecting to the tongue, whereby the hook is selectively connected to or separated from the tongue via the elastomer and the pusher when the controller is completely inserted into or ejected out of the space.
摘要:
An immunoassay for assaying an antigenic substance (Ag) in a fluid. The immunoassay is the type which comprises contacting the fluid with at least one first entity selected from a group consisting of an antibody (Ab) to the Ag, a soluble, labeled antibody (L-Ab.sub.a) to the Ag, and an antibody (Ab.sub.b) to the Ag bound to a solid support (SC). The immunoassay is characterized in that the fluid is contacted with at least one additional entity selected from a group consisting of at least one different type of soluble, labeled antibody (L-Ab.sub.c) to the Ag, at least one different type of antibody (Ab.sub.d) bound to a solid carrier (SC.sub.1), and at least one different type of antibody (Ab.sub.e) to the Ag. The SC.sub.1 is selected from a group consisting of SC, at least one different solid carrier (SC.sub.2), and mixtures thereof (SC and SC.sub.2). Each type of L-Ab.sub.c, Ab.sub.d -SC.sub.1, and Ab.sub.e has a lower average affinity constant (K) for Ag than each respective K of L-Ab.sub.a, Ab.sub.b -SC and Ab.sub. e ; and the additional entity is present in an amount sufficient to avoid a hook effect.Also, a reagent of the type comprising at least one first entity selected from a group consisting of L-Ab.sub.a, Ab.sub.b -SC, and Ab. The reagent is characterized in that it further comprises at least one additional entity selected from a group consisting of at least one different type of L-Ab.sub.c and at least one different type of Ab.sub.d -SC.sub.1, and at least one different type of Ab.sub.e. Ab, L-Ab.sub.a, Ab.sub.b -SC, L-Ab.sub.c, Ab.sub.d -SC.sub.1, and Ab.sub.e are as defined above.
