The present invention provides an anti-human hemoglobin monoclonal antibody or an antibody kit for specifically detecting and measuring a hemoglobin-haptoglobin complex in a sample with ease, and an insoluble carrier particle to which the monoclonal antibody is immobilized, and a measurement reagent and a measurement method for specifically detecting and measuring a hemoglobin-haptoglobin complex in a sample using the same. The anti-human hemoglobin monoclonal antibody of the present invention does not react to free hemoglobin or free haptoglobin which is not formed in a complex, but specifically reacts to a hemoglobin-haptoglobin complex when the antibody is immobilized to an insoluble carrier particle and used.

The invention relates to an immobilized protein material comprising a protein that is immobilized on a glass material or organic polymer through affinity tag binding. The glass material may be a porous glass material such as (hybrid) controlled porosity glass. The invention also relates to the use of an immobilized enzyme material as a heterogeneous biocatalyst in chemical synthesis. The invention further relates to a method for the immobilization of affinity tagged proteins on a glass material or organic polymer, and to a method for the purification and isolation of affinity tagged proteins by the immobilization of such proteins on a glass material or organic polymer.

Embodiments of templated polymeric materials capable of binding lysophosphatidic acids (LPAs) are disclosed. Methods of making and using the templated polymeric materials also are disclosed. The disclosed templated polymeric materials are molecularly imprinted polymers that bind LPAs and facilitate the production of lysophosphatidic acid-enriched samples, for instance through extraction of lysophosphatidic acids from biological samples, such as plasma or serum samples.

Fluidic connectors, methods, and devices for performing analyses (e.g., immunoassays) in microfluidic systems are provided. In some embodiments, a fluidic connector having a fluid path is used to connect two independent channels formed in a substrate so as to allow fluid communication between the two independent channels. One or both of the independent channels may be pre-filled with reagents (e.g., antibody solutions, washing buffers and amplification reagents), which can be used to perform the analysis. These reagents may be stored in the channels of the substrate for long periods amounts of time (e.g., 1 year) prior to use.

A method for measuring TAT complexes in a sample separated from a living body includes measuring TAT by performing latex immunoagglutination reaction under a condition of pH 5.8 to 6.6 using a TAT assay reagent. The TAT assay reagent includes a first antibody bound to a first latex particle, which binds to the antithrombin part of the TAT complex and recognizes the complex, and a second antibody bound to a second latex particle, which binds to the thrombin part of the TAT complex and recognizes the complex.

A method of determining a macromolecular analyte in a sample suspected of containing the macromolecular analyte is disclosed. The sample and a conjugate reagent comprising a small molecule and a binding partner for the macromolecular analyte are combined in a medium. The conjugate reagent and a labeled binding partner for the small molecule are combined. The conjugate reagent or the medium is examined for an amount of labeled binding partner for the small molecule that is bound to the small molecule, which is related to the amount of the macromolecular analyte in the sample.
