Abstract: A reagent kit used for detecting lipoprotein-associated phospholipase A2, and a preparation method for the reagent kit. The reagent kit comprises one or a plurality of first anti-lipoprotein-associated phospholipase A2 antibodies used for binding lipoprotein-associated phospholipase A2 to be measured, and one or a plurality of second anti-lipoprotein-associated phospholipase A2 antibodies marked with a trace marker and binding with the lipoprotein-associated phospholipase A2 to be measured at another site, different from the binding site of the lipoprotein-associated phospholipase A2 to be measured and the first anti-lipoprotein-associated phospholipase A2 antibodies. The reagent kit also comprises a displacing agent, so as to further increase the detection accuracy of the reagent kit.

Abstract: Provided are a detection agent for detecting hydroxy vitamin D, preparation method thereof, and use thereof in 25-hydroxy vitamin D immunological detection. The detection agent comprises a conjugate formed by a 25-hydroxy vitamin D antigen derivative and protein carrier, and magnetic spheres coated by the conjugate. Also provided is a 25-hydroxy vitamin D detection kit comprising the detection agent.

Abstract: A crucible for melting metals includes a main body, a bottom portion, and a strengthening annular portion. The bottom portion is sealed to a first end of the main body. The strengthening annular portion is disposed on a second end of the main body. The main body, which is also thicker towards the bottom portion for additional strength, and the bottom portion are composed primarily of graphite, and the strengthening annular portion is composed of a ceramic material or fireproof material or both.

Abstract: A processing room includes a processing chamber, a discharge chamber, a sealing member, a blocking member, and a reclaiming member. The discharge chamber includes a main body communicating with the processing chamber, and a receiving portion and a discharge portion communicating with the main body. The receiving portion is aligned to the discharge portion. The sealing member includes a sealing portion and a sealing valve mounted on the sealing portion. The sealing portion is partially and moveably received in the receiving portion and resists against a sidewall of the receiving portion. The blocking member is detachably mounted on an end of the discharge portion and seals the discharge portion. The reclaiming member is partially received in the main body.

Abstract: An amorphous alloy housing includes an amorphous alloy substrate and a wear-resistant protective layer formed on the amorphous alloy substrate by vacuum deposition technology. A method for making the amorphous alloy housing is also provided.

Abstract: The present invention provides a chemical-mechanical polishing (CMP) composition suitable for polishing a substrate comprising a phase change material (PCM), such as a germanium-antimony-tellurium (GST) alloy. The composition comprises a particulate abrasive material in combination with lysine, an optional oxidizing agent, and an aqueous carrier therefor. CMP methods for polishing a phase change material-containing substrate utilizing the composition are also disclosed.
