Abstract: Processes for quantifying an amount of functional groups immobilized on a solid support are described herein. The processes allow for determining whether sufficient functional groups are provided on a solid support for the attachment of a first binding pair member for the detection of a target analyte.

Abstract: A human insulin-like growth factor (IGF) binding protein stock solution and method of making the same include a non-recombinant human IGF binding protein-3 (nr-IGFBP-3) in an aqueous buffered medium. The concentration of the nr-IGFBP-3 in the stock solution ranges from about 16 micrograms per milliliter (?g/ml) to about 40 ?g/ml. A kit includes a set of calibrators for nr-IGFBP-3. The set of calibrators includes the nr-IGFBP-3 in different concentrations.

Abstract: Embodiments of the present disclosure include an electrical receptacle, comprising a base formed of electrically insulating material and arranged to hold at least one pair of electrically conductive terminals, and a cover formed of electrically insulating material and configured to be joinable with the base. The cover can comprise a top portion having a bottom surface, and at least one separating tab attached to the bottom surface at an angle of ˜90 degrees. Each separating tab can be arranged to separate opposite terminals, of a terminal pair, only when the cover is at least partially joined with the base. Base and cover can include, respectively, locking tabs and receptacles configured to engage when base and cover are fully joined. Embodiments also include power supply circuits comprising a DC-AC inverter, a load protection circuit, and embodiments of the electrical receptacle. Embodiments also include methods for protecting a power supply circuit.
