The Human PLAP/ALPP (Placental Alkaline Phosphatase) ELISA quantitates PLAP/ALPP in serum and plasma.
原理方法
The Human Placental Alkaline Phosphatase (PLAP/ALPP) solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the concentration of Placental Alkaline Phosphatase (PLAP/ALPP) in biological samples. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples, standards, or controls are added into these wells and bind to the immobilized (capture) antibody.
The sandwich complex is formed by the addition of a second (HRP-linked) detection antibody specific to Placental Alkaline Phosphatase (PLAP/ALPP). Excess reagents are washed from the plate.
A substrate solution is added that reacts with the enzyme-antibody-target complex to produce a measurable signal. The enzyme-substrate reaction is terminated by the addition of stop solution. The intensity of the signal, measured spectrophotometrically at 450 ± 2 nm, is directly proportional to the concentration of Placental Alkaline Phosphatase (PLAP/ALPP) present in the original specimen.
Rigorous validation:
Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.

Placental Alkaline Phosphatase plays an important role in the regulation of specific inflammatory disease processes. There are at least four distinct but related alkaline phosphatases: intestinal, placental, placental-like, and liver/bone/kidney for this form of alkaline phosphatase have been well characterized. Placental Alkaline Phosphatase reacts with a membrane-bound isoenzyme (Regan and Nagao type) of Placental Alkaline Phosphatase (PLAP) occurring in the placenta during the 3rd trimester of gestation. Placental Alkaline Phosphatase is useful in the identification of testicular germ cell tumors. Unlike germ cell tumors, PLAP-positive somatic cell tumors uniformly express epithelial membrane antigen (EMA). A proposed function of Placental Alkaline Phosphatase is matrix mineralization; however, mice that lack a functional form of this enzyme show normal skeletal development. Placental Alkaline Phosphatase has been linked directly to hypophosphatasia, a disorder that is characterized by hypercalcemia and includes skeletal defects. The character of hypophosphatasia can vary, however, depending on the specific mutation since this determines age of onset and severity of symptoms.
