ELISA and Immunoassays

Enzyme-linked immunosorbent assay (ELISA) is a biochemical technique to detect the presence of an antibody or an antigen in a sample. Whereas an indirect ELISA is used to determine the amount of antibodies to a specific antigen in a sample, a Sandwich ELISA is used to determine the concentration of the analyte by use of antibodies that bind to the analyte (and a standard). A different way of determining the analyte concentration is a competitive ELISA, often called EIA. This technique is preferred for small analytes.

Interleukin-6 (human) ELISA Kit
Interleukin-6 (human) ELISA Kit

Item number: Cay501030-96

Interleukin-6 (IL-6) is produced by multiple cell types, including monocytes, macrophages, and T cells and is involved in many defense mechanisms including the immune response, hematopoiesis, bone metabolism, and acute phase reactions. IL-6 promotes the proliferation of activated B-cells, acts as a B-cell...

Aldosterone ELISA Kit
Aldosterone ELISA Kit

Item number: Cay501090-96

Aldosterone, a steroid hormone secreted by the adrenal cortex, is the principle mineralocorticoid controlling sodium and potassium balance. Serum aldosterone levels in normal upright adult individuals are generally less than 300 pg/ml. Only a fraction of urinary aldosterone is excreted intact, thus urinary excretion...
