ELISA kit User Manual Human Neonatal Thyroid Stimulating Hormone N TSH ELISA Kit Catalog No BMA 3452 96T For Research Use Only Not for In Vitro Diagnostic Use Intended use The ELISA Kit is to be used for quantitative determination of Human Neonatal Thyroid Stimulating Hormone N TSH in serum Plasma and other biological fluids Kit is intended for research use only not for diagnostics 1 Principles of Method The Human N TSH ELISA Kit is an Vitro enzyme linked immunosorbent assay for the quantitative measurement of Human N TSH in serum plasma tissue lysates cell culture supernatants and urine The Human N TSH polyclonal antibodies are pre coated onto 96 well plate Standard and samples are aspirated into the wells and Human N TSH present in a sample is bound to the wells by the immobilized antibody The biotinylated detection antibodies are added to the wells and then followed by washing with PBS or TBS buffer After washing away unbound biotinylated antibody Avidin Biotin Peroxidase Complex is added to the wells The wells are washed again a TMB substrate solution is added to the wells and the color changes after adding acidic stop solution The intensity of the color is proportional to the amount of Human N TSH bound in samples and measured at 450nm 10nm 2 Reagents and Materials Provided Composition Quantity Composition Quantity Pre coated Micro titer plate 96 wells 1 Sample Diluent
