WebOne advantage of solid-phase PLA is the elimination of extensive, carefully controlled wash steps, as required for other solid-phase assays such as ELISA. Immobilization of the protein on a solid support can serve to purify … WebThe most commonly-used molecules that will bind to these surfaces are glycans. It is also suggested to use this surface for the immobilization of highly polar molecules or for homogenous assays of hydrophobic analytes which will not adhere to the hydrophobic surface. Binding to the very hydrophilic surface tends to be more pH sensitive. flashcards corps humain maternelle
