The Free Testosterone AccuBind® ELISA Test System is an Enzyme Immunoassay (EIA) for the quantitative measurement of free testosterone in human serum. Measurement of free testosterone is used in the diagnosis and treatment of disorders involving the male sex hormones (androgens), including primary and secondary hypogonadism, impotence in males and in females; hirsutism (excessive hair) and virilization (masculinization) due to tumors, polycystic ovaries and androgenital syndromes.

The kit consists of seven (7) vials of serum reference calibrators for Free Testosterone with two (2) controls (one low and one high); one (1) vial of Testosterone (Analog)-horseradish peroxidase (HRP) conjugate in a protein stabilizing matrix; one 96-well testosterone antibody-coated microplate; one (1) vial of concentrated wash solution; two (2) vials for tetramethy(benzidine (TMB) substrate solution preparation; and one (1) vial of stop reaction solution.

The Monobind AccuBind Neo-TSH Microwell Elisa Assay is an in vitro diagnostic test system for the quantitative determination of thyroid stimulating hormone (TSH) in human whole blood dried on Whatman 903 filter paper. It is intended to be used to screen newborns for congenital hypothyroidism.

The Monobind AccuBind™ Neonatal TSH Elisa Assay is a solid phase two-site immunoenzymometric assay based on the direct sandwich technique in which two specific antibodies are directed against two separate antigenic determinants on the hTSH molecule. In this method, TSH dried whole blood callbrator, patient specimen or control is first added to a streptavidin coated well. Elution buffer containing biotinylated monoclonal antibodies are added and the reactants mixed. Reaction between the biotinylated Anti-TSH and the TSH in the dried blood spot forms a complex that binds to the streptavidin coated to the inherent affinity of streptavidin and biotin. After the completion of the first incubation period, excess reactants are washed off via a wash step and the enzyme conjugate (another specific anti-TSH antibody linked to an enzyme) is added to the Ag-Ab complex deposited on the plastic surface. The enzyme labeled Anti-TSH antibody binds to the TSH making a sandwich complex with two antibodies bound to the antigen during a second incubation. The microplate is washed to remove unreacted enzyme. Finally, the activity of the enzyme present on the surface of the well is quantitated by reaction with a suitable substrate to produce color.

The test is intended for the quantitative determination of Thyroxine (T4) in blood specimens dried on the filter paper for screening newborns for congenital (neonatal) hypothyroidism.

The Measurement of the Total Amount of Binding Sites Available for the Thyroid Hormones in Human Serum or Plasma by a Microplate Enzyme Immunossay. Measurements obtained from this device are used in the diagnosis and treatment of thyroid diseases.

The Monobind microplate EIA utilizes limited amount of anti-thyroxine antibody coated on the surface of plastic wells of a microtiter plate. Specimens, calibrators or controls are then added followed by the enzyme-T4 conjugate and thyroxine. The amount of enzyme only gets to the specimen increases. After the completion of the incubation period, the enzyme-T4 conjugate on the well is quantitated by reaction with suitable substrate. The activity of the enzyme is inversely proportional to the amount of unsaturated thyroid hormone binding sites in the specimen. The employment of several serum references of known unsaturated thyroid hormone binding capacity permits construction of a graph of absorbance and concentration. From comparison to the dose response curve, an unknown specimen's absorbance can be correlated with thyroid hormone binding capacity.

The quantitative determination of follicle stimulating hormone (FSH) concentration in human serum and plasma by a microplate enzymeimmunoassay.Measurements of follicle-stimulating hormone are used in the diagnosis of pituitary gland and gonadotropin disorders.

Monobind Inc., registration number 2020726, plans to introduce Into commercial distribution an enzymeimmunoassay (ELISA) kit for the determination of folliclestimulating hormone (FSH) in human serum and plasma. The Monobind ELISA method is based on two-site immunoassay (sandwich) technology utilizing the streptavidin-blotin reaction to effect separation. Upon mixing monoclonal blotinylated anti-FSH antibody, the enzyme-labeled anti-FSH antibody and a serum containing the native antigen (FSH), reaction results between the native antigen (FSH) and the antibodies, without competition or steric hindrance, to form a soluble sandwich complex. Simultaneously, the complex is deposited to the well through the high affinity reaction of streptavidin and biotinylated antibody. After incubation is complete, decantation or aspiration separates the bound fraction. The enzyme activity on the well Is directly proportional to the native antigen (FSH) concentration. By utilizing several different serum references of known antigen values, a dose response curve can be generated from which the antigen concentration of an unknown can be ascertained.

The quantitative determination of thyroid peroxidase (TPO) autoantibodies in human serum or plasma by a microplate enzymeimmunoassay. Measurements of TPO autoantibodies may aid in the diagnosis of certain thyroid diseases such as Hashimoto, Graves, and nontoxic goiter.

The Monobind method is based on ELISA technology utilizing the streptavidin-blotin reaction to effect separation. Upon mixing blotinylated thyroid peroxidase antigen, and a serum containing the autoantibody (anti-TPO), reaction results between the biotinylated theroid peroxidase antigen and the antibodies to form an immune complex.
