<p>The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Pig PYD. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Pig PYD. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Pig PYD, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Pig PYD in the samples is then determined by comparing the OD of the samples to the standard curve.</p>

<p>Applications Xylan is a major constituent of the secondary cell wall and plant cell-wall polysaccharides. Xylan is also used in the studies involving structural properties, foaming as a new means for food structuring in plants. Xylanases an enzymatic form of xylan is used in several biotechnological processes, primarily for biopulping and biobleaching in the paper industry and as accessory enzymes for bioethanol production.<br>References Yuan, Y., et al.: Plant and Cell Physiol., 57, 35 (2016); Kuang, B., et al.: Mol.

<p>Applications Cetyl Stearate is a wax ester of stearic acid. Wax esters are esters between long chained fatty alcohols and fatty acids. Wax esters have significance in pharmaceutical and cosmetics applications and occur naturally in plants and animals. Stearate esters are used most frequently in the formulation of eye makeup, skin makeup, lipstick and skin care products.<br>References Wheatley, V., et al.: Biochem.
