Description

Progesterone Saliva ELISA KitThe Progesterone Saliva ELISA kit is a competitive ELISA to measure Progesterone in saliva. Competition occurs between progesterone present in calibrators, controls, specimen samples and an enzyme labelled antigen (HRP conjugate) for a limited number of anti progesterone antibody binding sites on the microplate wells. After a washing step that removes unbound materials, the TMB substrate (enzyme substrate) is added which reacts with HRP to form a blue

The Progesterone Saliva ELISA kit is a competitive ELISA to measure Progesterone in saliva. Competition occurs between progesterone present in calibrators, controls, specimen samples and an enzyme-labelled antigen (HRP conjugate) for a limited number of anti-progesterone antibody binding sites on the microplate wells. After a washing step that removes unbound materials, the TMB substrate (enzyme substrate) is added which reacts with HRP to form a blue-colored product that is inversely proportional to the amount of progesterone present. Following an incubation, the enzymatic reaction is terminated by the addition of the stopping solution, converting the color from blue to yellow. The absorbance is measured on a microplate reader at 450 nm. A set of calibrators is used to plot a calibrator curve from which the amount of progesterone in specimen samples and controls can be directly read.

Super cute and comfortable
Size: 7, Color: Natural Snake
I love these shoes. The heel height is perfect for me, they’re very cute and feel pretty secure on. My first time wearing these I was able to keep them on all night. I took off one star because the little gold circle can cause some pressure/discomfort on the toes
